Introduction, Features, and Accessories
• INTRODUCTION
Aqua-Barriers are a water-inflated damming device produced from flexible reinforced PVC membrane material. The Aqua-Barriers are used as a temporary water diversion system in construction projects, flood protection and numerous other applications. Aqua-Barriers are characterized by being light- weight, easily deployed and removed, compact in storage, repairable and reusable.
Stabilization Components
Three components interact together to
stabilize the Aqua-Barrier water-inflated dam.
Internal Baffle System
The internal restraint baffle(s) lock into place when
the barrier is exposed to uneven hydrostatic
pressure on one side.
Freeboard (amount of inflated barrier above
the surrounding water level)
A minimum of at least 25% freeboard is required in all
Aqua-Barrier®installations. Freeboard requirements
may increase if the barrier is exposed or has the potential to being exposed to surface water velocities of 3ft or more per second, slick soil conditions or other relevant hydrostatic conditions.
Surface Friction
The Aqua-Barriers also require surface friction to stabilize when exposed to uneven hydrostatic pressures. Barriers that are exposed to weak soils and/or slick soil conditions may require supplemental support, a wider footprint or additional freeboard, as directed by an engineer.
• PRODUCT FEATURES
Aqua-Barriers are designed with unique accessories to facilitate installation and removal.
Internal Baffle System
Aqua-Barriers®utilize a unique internal baffle for
stability that also allows for single-port inflation.
Floatable Fill and Drain Caps
All fill and drain caps are designed to float,
perfect for easy tracking and recovery if dropped
into the water.
Patented End Pipeloop
Our Patented End Pipeloopallows for a safe
connection point for heavy equipment to utilize
when adjusting or moving a deflated Aqua-Barrier®.
In-Field Repairable
Heavy gauge vinyl patches allow you to repair the Aqua-Barrier®throughout your project duration, wet or dry.
4” PVC Elbows
4” Pipe Elbows are used when filling the AquaBarrier®with water. The adaptable 4” female end, utilizing standard threads, allows for multiple size pumps and\or hose fittings like cam-lock or Baur fittings to suit your needs.

Aqua-Barrier Technical Information
• GENERAL INFORMATION
MAINTENANCE:
To maintain Aqua-Barriers simply repair worn and punctured areas with the available repair material. Repairing is best accomplished when the barrier surface has been cleaned. Follow the repair instructions provided in this manual or on the can of Vinyl adhesive HH66. It is recommended that the Aqua-Barriers® be inflated with air in order to inspect for problem areas and repair as needed. Always allow the barrier surface to dry before tightly rolling up for storage.
STORAGE:
Store Aqua-Barriers in a covered area, away from harmful UV rays. Do not store where barriers will be in contact with solvents, acids or rodents. Do not store in an area that experiences temperatures that fall below 32° F or above 150° F.
DEFINITIONS:
Dynamic Load – Water pressure created by moving water and/or wave action.
Free Board – Part or height of barrier extending above water surface.
Hydrostatic Pressure – Water pressure.
Static Load – Water pressure created by standing or non-moving water.
PVC – Vinyl Coated Polyester. Material used to produce Aqua-Barriers.
SAFETY INSTRUCTIONS –DEFINITION OF TERMS
• AQUA-BARRIER BAFFLE BEHAVIOR
The Aqua-Barrier system gains its stability through the tensioning of the inner
restraint baffle(s). Once the system is inflated, the baffles prevent the barrier from rolling over. As the barrier is exposed to water pressure there is a natural adjustment towards the side of the least hydrostatic (water) pressure.
The maximum length of lateral movement toward the side of least water resistance is 1/2 of the properly inflated barrier height (i.e., 4-ft tall barrier can adjust as much as 2 ft). The adjustment lengths are based upon a barrier being inflated to its recommended height with the baffle being cross-sectional centered. The barrier adjustment length could increase or decrease if not properly inflated and or if slopes or grades are present. These adjustments should be considered when determining the installation location of the barriers.
Maximum Adjustment per Aqua-BarrierHeight
Baffle Stabilization Process -Dewatering
Baffle Stabilization Process –Flood Protection
• STANDARD HEIGHTS AND DIMENSIONS
This depth of water represents 75% of the height of a fully inflated dam. It is required that a 25% freeboard capacity be maintained in static water environments during all phases of a project.
HSI Services, Inc. is NOT responsible for barrier replacement or repair if static water level exceeds 75% of the barrier inflation height, e.g. 4.5-ft water level on a 6-ft high barrier. In moving water environments, or potentially moving water environments, HSI Services, Inc. will designate a maximum water percentage height on a given barrier height. If water level exceeds either of these limitations, the warranty will be considered null and void.
Excess slope and grade, soil composition, moving water and related hydrological criteria may increase or decrease the ability of the AquaBarrier®to perform as projected.
• STANDARD HEIGHTS AND DIMENSIONS
Pre-Installation Warnings
• WORKSITE SAFETY
When working within the Aqua-Barrier® dewatered area it is required that all federal, state and local safety procedural laws are followed. At a minimum, the company utilizing the Aqua-Barrier®system must comply with OSHA trench and excavation safety procedures. These regulations can be found online at www.osha.gov
A competent person(s) is required onsite at each work shift during the use of the Aqua-Barrier® system when workers are present. The competent site person is required to inspect the barriers if there has been any change in water depth, height of inflated barrier(s) or change in position. The OSHA definition of a competent person is as follows:
COMPETENT PERSON is an individual who is capable of identifying existing and predictable hazards or working conditions that are hazardous, unsanitary or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate or control these hazards and conditions.
• IMPORTANT INFORMATION WHEN USING WATER INFLATED COFFERDAM SYSTEMS
Establishing a temporary cofferdam system and dewatering the enclosed area is a process with inherent problems. These problems arise from the inability to gather exact site conditions because water coverage prevents visibility of the underwater surface conditions. Soil conditions directly under the visible surface may also pose unexpected problems such as objects that could damage the barrier and/or porous soil conditions. Extensive site evaluations can be performed, however, it is impossible to precisely determine all relevant hydrological conditions that could affect the success of the water inflated cofferdam system.
Complete inability to keep a barrier inflated if large punctures occur: Recommended solution to the problem is to remove barrier, perform onsite repair, and remove debris that caused the problem or apply protective membrane. If the damage has rendered the barrier un-repairable, a replacement unit will be needed.
Loss of inflation due to small leaks in the
barrier recommended solutions: 1) Perform
onsite repair using the repair kit provided with
your order. 2) Remove the barrier to allow the
removal of debris that caused a problem or
apply a protective membrane at installation
location prior to re-installing the barrier. 3)
Maintain recommended inflated height of barrier
by adding water as needed.
=
Moving water environments: Bodies of moving water can behave in unusual ways when partially or completely blocked with a temporary damming system. Reducing the normal channel dimensions can cause water depths and velocities to increase. Rain events, channel flows, irregular surface conditions, soil makeup, and other relevant hydrological information may affect the overall effectiveness of the damming system. Due to these unknown behaviours; the original cofferdam design may require alterations.
Slick soil conditions: In environments exhibiting limited surface friction; adjustments to the freeboard (amount of inflated barrier above the surrounding water) and/or a temporary structure may be required for barrier stabilization and must be certified by a licenced professional engineer on a project by project basis. Environments such as lakes, ponds, or other standing water environments are susceptible to long term silt build up. This soft silt media offers very little surface friction. Slopes, grades, and other relevant hydrological data can affect the ability of the inflated barrier to perform successfully in these environments. In the event that not enough soil friction exists to stabilize the system, a structural support such as steel pipes can be used to achieve stability andpreventsliding.
Thorough site preparation is essential to avoiding the problems mentioned above.
• HAZARDS
CONSTRUCTION & DEWATERING APPLICATIONS
• Due to close proximity of water, HSI Services, Inc. recommends the use of a Coastal Guard approved PFD (Personal Floatation Device) during the installation and removal process of an Aqua-Barrier®.
• Aqua-Barriers® can slide into the dewatered worksite in the event that the designated freeboard requirements stated in the Standard Heights and Dimensions charts, page 11, are exceeded. Minimum freeboard requirement is 25%. Aqua-Barriers ® can be pushed or floated downstream/out of place in a moving water environment due to loss of freeboard or high water velocities.
• Aqua-Barriers® can slide into the dewatered area if the surface friction is not stable enough to support the barrier.
• Aqua-Barriers® can lose their stability and slide into the dewatered area if its recommended inflation height is not maintained.
• Aqua-Barriers® can be vandalized by cutting the exterior of the system or removing the drain ports.Aqua-Barriers® can be vandalized by cutting the exterior of the system or removing the drain ports.
• Avoid deploying Aqua-Barriers® near any electrical sources (i.e. ground transformers, power poles and lines, junction boxes, switch gears, etc.). Please inquire and adhere to all Overhead Power Line Safety Laws and OSHA requirements when elevating the Aqua- Barriers®. HSI Services, Inc. cares about the safety of those working near electrical sources. Accidents involving contact with high voltage can result in serious injury or death. When power lines are present on or near the work site, the safety of the equipment operation is the responsibility of the personnel in charge of the work site. Before setting up or operating equipment on any project:EVALUATE THE original installation positions WORK SITE FOR HAZARDS , including both overhead and underground, and if present EXERCISE EXTREME CAUTION .

FLOOD PROTECTION APPLICATIONS
• Aqua-Barrier®.canslideintotheprotected area in the event that the designated freeboard requirements stated in the Standard Heights and Dimensions charts, page 11, are exceeded. Minimum freeboard requirement is 25%. Aqua-Barriers® can be pushed or floated out of place in a moving water environment due to loss of freeboard or high water velocities.
• Aqua-Barriers® can slide into the protected area if the surface friction is not stable enough to support the barrier. Aqua-Barriers® can lose their stability and slide into the protected area if its recommended inflation height is not maintained.
• Aqua-Barriers® can be vandalized by cutting the exterior of the system or removing the drain ports.
• SAFEGUARDS AND PRECAUTIONS
• Each individual involved in the installation of the Aqua-Barrier®system is required to have a cutting tool (i.e. knife, razor blade, box cutter, etc.) readily accessible in the event of being trapped in some manner by an AquaBarrier®. Have an evacuation plan in case the water level exceeds the height capacity of the Aqua-Barriers®.
• Every work site should have a deployment and recovery plan. Assistance can be provided regarding this plan by your local HSI Services, Inc. representative.
• The recommended safety space between workers and the inflated Aqua-Barriers®is 10ft-12ft. A minimum operating distance of 10ft should be maintained between heavy equipment and the inflated Aqua-Barriers®. When work requires excavating near AquaBarriers®and the excavation depth will exceed 1ft, you must allow an additional easement area of 1ft (in addition to the required 10ft) away from the barriers and excavation area for each additional foot excavated. The OSHA trench and excavation guidelines should be followed at all times when working with Aqua-Barriers®. Personnel should avoid walking on the AquaBarriers® unless they are accessing the fill/drain ports or checking the AquaBarrier® inflated height.
• When installing, working around inflated Aqua-Barriers®, or removing Aqua- Barriers®, a minimum crew size of 3 workers is mandatory.
• Do not stack objects (i.e.: sandbags, bricks, or another Aqua-Barrier® unit) on top of the Aqua-Barrier®system to increase height.
• It is recommended that you monitor the inflated Aqua-Barrier(s)®24-hours a day. This will deter any vandalism and be a source of information if any problems occur.
• If Aqua-Barriers®are installed near major roads, overpasses, or recreational boating areas it is recommended a puncture resistant cover be placed over the barriers to protect against floating/thrown objects.
• Aqua-Barriers®are only a surface water treatment. Water can transmit under the barriers depending on soil porosity. Sump pump area(s) are required in all dewatering projects. The size and number of sump pumps will depend upon the porosity of the soil.
• SAFEGUARDS AND PRECAUTIONS FOR FLOOD PROTECTION APPLICATIONS
• Block all ways that flood water can invade
the property being protected (i.e.: plug toilets and other drains). Shut off main water line leading to the protected property.
• The recommended safety space between the protected property and the AquaBarriers®is 10ft to 12ft.
• It is recommended to monitor the inflated Aqua-Barrier(s)®24-hours a day. This will deter any vandalism and be a source of information if any problems occur.
• You must install the Aqua-Barrier®2X the inflated height away from the protected structure (i.e. a 2ft tall Aqua-Barrier®must be installed at least 4ft away from the protected property).
• Do not install an Aqua-Barrier®on surfaces unable to bear the weight load such as decks and balconies.
The following websites offer additional flood safety information:
• EVACUATION PROCEDURE
If, in the event the water depth where the AquaBarriers®are to be installed at is expected to exceed the 25% freeboard or recommended freeboard requirement, the worksite should be evacuated.
The evacuation plan is as follows:
All personnel should be evacuated from the dewatered worksite. The worksite equipment can be evacuated if the competent person believes that it is safe.
The Aqua-Barriers® removal process can begin if it is determined that there is sufficient time for removal of the barriers before the 25% freeboard or recommended freeboard requirement is exceeded. Reference pages 56-60 for removal procedures and additional instructions.
In moving water environments, all personnel involved with the removal process should position themselves on the upstream side of the barrier before the actual removal process begins. Water should then be released from the barrier into the dewatered area to equalize the water pressure on both sides of the Aqua-Barrier®prior to removing the drain ports on the watered side of the barrier.
Each installed Aqua-Barrier®is to be removed from the worksite. An HSI Services, Inc. trained advisor can instruct onsite personnel with regard to the proper removal process during the installation training and removal session which may take place on site or virtually prior to installation.
Preparing Your Worksite
• SITE PREPARATION AND INSTALLATION PRECAUTIONS
• All ground objects that could puncture the Aqua-Barriers®(i.e. sharp rocks, broken glass) should be carefully removed or avoided when deploying. If deploying in a standing or moving water environment, manually walking the site or drag netting will ensure a properly cleared area. When the deployment site cannot be totally cleared of problem objects, it is recommended that a protective material be installed on the site (i.e. non-woven geo textile or other forms of puncture and abrasion resistant plastic sheeting) prior to deployment.
• Before setting up or operating equipment on any project: EVALUATE THE WORK SITE FOR ELECTRICAL HAZARDS,including both overhead and underground,and if present EXERCISE EXTREME CAUTION.
• Identify the water source that will be used to inflate barriers and maintain clear access to it. Using the shortest length of hose to fill the Aqua Barriers® is preferred because less hose transmits more water volume. Reference page 35-36 for instructions on theproperuseofa suctionhose.
• Identify the water source that will be used to inflate barriers and maintain clear access to it. Using the shortest length of hose to fill the Aqua Barriers® is preferred because less hose transmits more water volume. Reference page 35-36 for instructions on theproperuseofa suctionhose.
• Assessment of slopes and land contours is very important when evaluating an optimal area for installing Aqua-Barriers®. If the area needing protection is characterized by hills and valleys, barriers may only be needed in the valleys. A barrier will only fill to its expected inflated height at the lowest point it encounters along its length. It is recommended that you consult your local Aqua-Barrier® representative for assistance prior to deployment if faced with extreme landcontours.
• SITE PREPARATION AND INSTALLATION PRECAUTIONS
• It is required that all of the Safeguards and Precautions and Hazards sections be carefully read prior to installing an Aqua-Barrier® system.
• The inflated height of the Aqua-Barrier® system is measured at the point of lowest elevation where the system is installed. The system must be monitored during the entire inflation process.
• Once the recommended inflation height is achieved, measured from the point of lowest elevation, the inflation process has been completed.
• Caution must be given never to over-inflate an Aqua-Barrier® system. It is recommended that you consult your local Aqua-Barrier® representative for assistance prior to deployment if faced with extreme land contours.
• Personnel involved in the installation and removal process should never position themselves beneath any elevated portion of an Aqua-Barrier® or piece of equipment.
• During all Aqua-Barrier® installations, the barriers can tractor or rotate toward the side which possesses less hydrostatic pressure or water depth. The maximum length of movement toward the side of least water resistance is 1/2 of the properly inflated barrier height (i.e., 4-ft tall barrier can adjust as much as 2 ft). See Baffle Behavior on page 10 to determine the adjustment length for your specific Aqua-Barrier® system. The same adjustment behaviour can occur if a slope or grade exists from one side of a barrier to the other. Aqua-Barrier® units that are not inflated to their proper height can tractor toward the dewatered area more than 1/2 of the recommended inflation height. Never over inflate an Aqua-Barrier® system. Reference page 28 for additional information on overinf lation.
• SITE PREPARATION AND INSTALLATION PRECAUTIONS
• For Flood Protection Applications Only:
Locate overflow fittings along the top prior to inflating the system. Screw on the provided stand pipe into the overflow fitting. Once water begins to flow out of the top of the stand pipe, the system has been completely inflated. Immediately stop the inflation process once this happens. If you continue to inflate your barrier after water has begun escaping from the stand pipe, you could cause the system to rupture. It’s imperative that you don’t over inflate your AquaBarrier® system.
• Apply 100% silicone caulk to all cracks, crevices, etc. to prevent water from seeping under the barrier via those cracks and crevices.
Installing your Aqua-Barrier®
• INSTALLATION PROCEDURE
There are three primary types of Aqua Barrier® installations. The following descriptions of the various types of installations are simplified and are only meant to give a general overview of the installation process. Assistance on proper installation procedures can be provided by a trained Aqua-Barrier® representative.
Drysurfaceinstallation: The location where the barriers are to be installed has no water present. The barriers are simply unrolled and inflated. This style of installation is generally used in anticipation of flood waters.
Staticwaterinstallation: Non-moving water is present at installation location. The barriers are buoyant and float on the waters surface when empty. The barriers are placed at the waters edge, unrolled on the water’s surface and floated into position.
Dynamic waterinstallations: Dynamic or moving water is present at installation location. Barriers are positioned properly by controlling the ends of the unit with hydraulic equipment (i.e. 200 series or larger track hoe, crane) in junction with the patented end pipe loops and/or anchoring at least one end of the barrier at the shoreline.
• CORRECT INFLATION
Note: The example illustrations above are using 8ft tall Aqua-Barriers®
• OVER-INFLATION AND PREVENTION
Note: The example illustrations above are using 8ft tall Aqua-Barriers®
• OVERLAP METHOD
Aqua-Barriers®are joined together by an overlapping technique. Once the initial Aqua-Barrier®has been inflated, the adjoining barrier is positioned and pulled up onto the end of the inflated barrier. The chart on page 30 illustrates the required barrier overlap lengths for each type of connection.
The barrier positioned on top of the inflated barrier is then inflated. The weight of the second barrier will provide downward force to seal the connection joint. Barriers can be joined end to end or at various other angles as Aqua-Barriers®are joined together by an overlapping technique. Once the initial Aqua-Barrier®has been inflated, the adjoining barrier is positioned and pulled up onto the end of the inflated barrier. The chart on page 30 illustrates the required barrier overlap lengths for each type of connection. depicted on page 30.
Note: The example illustrations above are using 8ft tall Aqua-Barriers®
• OVERLAP REQUIREMENTS
All 90 degree overlaps must be created with the required linear footage stated on the chart above. All other overlaps, unless specified by your Aqua-Barrier®representative, must be created with the standard overlap length stated above.

• PROPER USE OF A SUCTION HOSE
Proper Use: Option 1
(Bucket Method)
Submerge suction hose intake within an appropriately sized bucket to avoid sediment from being siphoned into the barrier during inflation.
Proper Use: Option 2
(Floatation Device Method)
Submerge suction hose intake with support of a floatation device to keep it off of the floor of your water source to avoid sediment from being siphoned into the barrier during inflation.
• IMPROPER USE OF A SUCTION HOSE
Improper Use
Do not allow suction hose intake to contact water source floor to avoid sediment from being siphoned into the barrier during inflation as shown below
• SEEPAGE DISCLAIMER®
The Aqua-Barrier water inflated dam system when properly installed is a temporary barrier against surface water. HSI Services, Inc. accepts no responsibility for water migrating under the Aqua-Barrier® system. The volume of water migrating under the Aqua-Barrier® is a function of soil porosity. A sump area where water can gather and be evacuated during the life of the project is required. The size and number of sump areas would depend on the size of the area being dewatered and porosity of the soil.
Use a pump on the dry side to control seepage that may occur under the barrier due to weak and porous soil.
You may also lay a sheet of plastic sheeting under the Aqua-Barrier® on the watered side and lay a row of sandbags over it. This can create a “vacuum” and help minimize seepage.
Another option to control seepage is to apply a row of sand bags on the watered side of the barrier.
You may also lay a sheet of plastic sheeting draped atop the AquaBarrier®and tucked underneath the watered side wedged in with sandbags. Be sure to weigh down the sheet on top of the barrier as well as the submerged sheet edge.
• RECOMMENDED LIFTING PIPE INSTALLATION PROCEDURE
The following is subject to change due to site conditions. Reference Equipment Checklist provided by your HSI Services, Inc. representative.
Step 1: Insert steel pipe into pipe loop.
Step 2: Attach (3) 3/4 inch x 15 feet ofrope to the steel pipe at the cut outs. These three ropes should then be attached to the lifting apparatus.
• LIFTING TIMBERS INSTALLATION PROCEDURE
• STATIC WATER MANUAL DEPLOYMENT
Step 1: Unroll and unfold barrier on solid ground near deployment area perpendicular to the deployment area shoreline.
Step 2: Scrunch barrier up to shoreline edge in deployment area, then pull the waterside end of the barrier to extend into the deployment area waters, leaving one end partly on shore
STEP 4: Repeat steps 1-3 until all barriers are in place. The last barrier placed (on top) should then be inflated to its designated full inflation height measured from the lowest point of elevation.
STEP 5: Repeat step 4 with the
remaining barriers in reverse order of
installation.
Drain the remaining water from your work area. Sump pumps are required throughout the duration of the project.Top off all barriers to their fullest height. It is necessary for all Aqua-Barrier® to be fully inflated throughout the duration of the
project.
STEP 3: Inflate deployed barrier to 6 inches above the water level and repeat steps 1 and 2 with the second barrier, treating the first barrier as a shoreline. Make sure to create your overlaps with the required linear footage as shown on page 30. Inflate the second barrier 6 inches above the water level.
• DRY SURFACE AND FLOOD PROTECTION DEPLOYMENT
Step 1: Unroll the Aqua-Barrier®system.
Step 2: Unfold the Aqua-Barrier®system from the center out. Insert the stand pipe into the over-inflation fitting.
Step 3: Connect a hose to the fill port.
Step 4: Once water begins to flow out of the top of the stand pipe, the system has been completely inflated. Immediately stop the inflation process once this happens. If you continue to inflate your barrier after water has begun escaping from the stand pipe, you could cause the system to rupture. It’s imperative that you don’t over inflate your Aqua-Barrier®system.
• DRY SURFACE AND FLOOD PROTECTION OVERLAP DEPLOYMENT
Step 1: Unroll the Aqua-Barrier®system.
Step 2: Unfold the Aqua-Barrier®system from the center out.Insert the stand pipe into the overinflation fitting.
Step 3: Fold the first unit back and place your second unit UNDERthe first one. Then fold the first unit back on top of the second unit. Make sure to create your overlaps with the required linear footage as shown on page 30.
Step 4: The last barrier placed (on top) should then be inflated until water begins to flow out of the top of the stand pipe, this means the system has been completely inflated. Immediately stop the inflation process once this happens. If you continue to inflate your barrier after water has begun escaping from the stand pipe, you could cause the system to rupture. It’s imperative that you don’t over inflate your Aqua-Barrier®system. Finish filling the remaining barriers in reverse order of installation.
• DYNAMIC WATER DEPLOYMENT USING 1 TRACK HOE AND SHORELINE ANCHOR
• DYNAMIC WATER DEPLOYMENT USING 2 TRACK HOES
• STEEL PIPE SUPPORT
Use 2” or 3” diameter heavy wall steel pipes to support the barriers on slick surfaces or fast-moving water. Reference page 50 for additional information.
1. The steel pipe support technique may be advised f®or all Aqua-Barrierinstallations dealing with slick surfaces or fast-moving water, when directed by a licensed engineer.
2. When utilized, steel pipes are to be driven into the ground as needed to reach a solid foundation. The steel pipes must extend a minimum of 1ft above the top of the barrier, slightly angled towards the barrier as depicted on the left.
3. Stabilizing steel pipes must be driven on both sides of the barrier with a spacing directed by engineer. You may contact HSI Services, Inc. or your local 4. ®Aqua-Barrierrepresentative for a site evaluation.
• DIVERSION PIPE AND BYPASS PUMP APPLICATIONS
In applications that require continuous water flow to be completely cut off such as a bank to bank block, it may become necessary to maintain water flow using diversion pipes or bypass pumps. Below are examples of this being done.
BYPASS PUMP AROUND
BYPASS PUMP AROUND
• CREATING A SEAL AGAINST DIVERSION PIPES AND VERTICAL WALLS
Lay down your diversion pipe and create a sandbag ramp on both sides to ease the slopes against the pipe. When completed, you may install your Aqua-Barrier®.
Create a sandbag ramp against the vertical wall(s) first. Your ramp should be the half the width of the barrier –centered –and at least 3ft high. When completed, you may install your Aqua-Barrier®.
The number of sandbags needed depends on the barrier size and relevant site conditions. Contact HSI Services, Inc. or your local Aqua-Barrier® representative for assistance.
• INSTALLING IN FREEZING CONDITIONS
In freezing conditions, it is recommended that all ice and snow be removed prior to installation. Failure to do so may affect barrier stability and integrity.
The Aqua-Barrier®material will hold down to -22°F. Anything below -22°F makes the material brittle. Typically, water inside the barrier is 10 degrees warmer than outside temperature.
You can keep the water inside from freezing solid by using products such as glycol tubes. You can also use ground heaters to warm up the barriers from the bottom. Thermal pool blankets to cover the top may also be helpful.
If you think the barriers will freeze you need to leave the fill ports open and release a little water out of the barriers after you’ve inflated them completely. Water expands at a rate of 10% when it freezes so you will want to deflate the barrier to 90% capacity to allow for the water expansion, this may prevent internal rips in the material as water turns to ice.
If the body of water in which the barriers are installed starts to freeze you may risk damage from ice ramming the barriers. To minimize this damage, you can cover the barriers with a geo textile protective membrane or place something in front of them to “catch” chunks of ice. Concrete jersey barriers work well and sometimes PE construction fence has been used. HSI Services, Inc. also offers an additional protective membrane which can be installed over the barriers when working in freezing conditions.
When it comes time to remove the barriers, they must be fully thawed and drained before you begin to pull them out of the water. Do not attempt to remove a barrier with ice inside as it could cause permanent damage.

Removal Procedures
• REMOVAL PROCEDURES
There are three primary types of Aqua-Barrier removal procedures. The following descriptions of the various types of Aqua-Barrier® removal procedures are simplified and are only meant to give a general overview of the removal process. More detailed removal procedure information can be provided by a trained HSI Services, Inc. representative on all Aqua-Barrier® removals.
Dry Surface Removal
When no water is present on either side of the Aqua-Barrier®: Locate the drain ports along the sides and ends of the barrier and remove the plugs. Once a majority of the water has drained from the barrier, you will be able to force the remaining water out by flipping the barrier over itself. Evacuate all water and get ready for storage/return. Reference Folding Procedures on page 61 for additional information.
Static Water Removal
When standing water is present on one side of the barrier only: First attach one end of the barrier to the hydraulic equipment arm (ie: track hoe, crane). Water must be equalized on both sides of the Aqua-Barrier® prior to removing it from the water. You will first need to pump the water back into the dewatered area to equalize pressure on both sides of the barrier. Failure to do this before removing the caps from the drain ports could flood your work area and potentially damage the barrier(s). Once the water has equalized on both sides of the barrier, you will locate the drain ports on both sides of the barrier and remove the caps. You can now pull one end of the barrier over the top and down the length of the barrier. This process will evacuate the remaining water and prevent cuts and abrasions on the bottom of the unit. Once you’ve evacuated all the water, you will get your barrier(s) ready for storage/return. Reference Folding Procedures on page 61 for additional inf ormation.
Dynamic Water Removal
When moving water is present on one side of the barrier only: First attach both ends of the barrier to the hydraulic equipment arm (ie: track hoe, crane). Water must be equalized on both sides of the Aqua-Barrier® prior to removing it from the water. The pipe loops on both ends of the Aqua- Barrier ® must have pipes inserted and attached to hydraulic equipment (i.e. track hoe, crane, etc.) to provide control of the barrier. Locate the drain ports on the dry side of the barrier only and remove all plugs. Once the majority of the water has drained from the barrier you can remove the plugs on the opposite side of the barrier. You can now pull one end of the barrier over the top and down the length of the barrier. This process will evacuate the remaining water and prevent cuts and abrasions on the bottom of the unit. Once you’ve evacuated all the water, you will get your barrier(s) ready for storage/return. Reference Folding Procedures on page 61 for additional inf ormation.

• REMOVAL USING 1 TRACK HOE
FOLDING PROCEDURE
Barrier must be secured on the pallets they arrived in with NO OVERHANG
STEP ONE:
After all caps are attached to each fill and drain port, lay barrier out flat on dry land.
STEP TWO:
Fold one side to the center. Then fold the other side to the center.
STEP THREE:
Take both sides and fold to center again.
STEP FOUR:
Roll and place on pallet (it is recommended to use a protective covering on the pallet). Secure the barrier to the pallet using rope or plastic banding strap and ensure there is no overhang.
REPAIR INSTRUCTIONS
1.Locate the puncture, cut, tear or abrasion on the barrier’s surface. Locate the patch material and cut a generous sized repair patch. Clean and remove all debris from the damaged area.
2.Apply a generous layer of the HH66 vinyl adhesive on the smoothside of the patch material, make sure to cover the patch entirely with adhesive. Apply a generous layer of the HH66 vinyl adhesive on both the damaged area and the surrounding area. The covered surrounding area should be slightly larger than the repair patch’s size.
3.Allow a few minutes for the adhesive to dry until it exhibits a frosty marble white color and is tacky to the touch. This can take anywhere from 1 minute to 5+ minutes depending on weather and temperature variables.
4.Apply the patch material centered over the damaged area. You will need to firmly press on the center of the patch while working your way around its entirety to prevent water from escaping the damaged area. Apply a good amount of pressure on the entirety of the patch from the center out to bond the patch and barrier surface together securely, be sure to not to trap any air bubbles during this process. You may need to keep pressure on the patch for a few minutes depending on the size of the damaged area; the larger the damaged area, the longer you may want to keep pressure on the patch.
Disclaimer: The HH66 vinyl-coated adhesive loses adhesion properties when applied in temperatures below 40°F. It is recommended that the adhesive be stored in an area where temperatures do not fall below 40°F.
See HH66 MSDS for additional safety precautions and recommendations
