WATER-INFLATED DAMS
Aqua-Barrier is a water filled dam that utilizes a patented internal baffle for stability.
Barriers come in multiple sizes
Inflated height (m) | Maximum controllable water/sediment depth (m)* | Inflated volume (l) | Inflated width (m) | Connection overlap (m) |
0,9 | 0,69 | 496,5 | 2,1 | 1,35 |
1,2 | 0,9 | 852,8 | 2,7 | 1,8 |
1,5 | 1,14 | 1334 | 3,4 | 2,25 |
1,8 | 1,37 | 1917,7 | 4,1 | 2,7 |
2,4 | 1,8 | 3414,8 | 5,4 | 3,6 |
* – The depth of water represents 75% of the inflated height of a fully inflated Aqua-Barrier. It is required that a minimum 25% freeboard (portion of barrier above water level) inflated capacity be maintained during all phases of a project. Excess slopes and grades, soil composition, moving water, and other related hydrological criteria may increase or decrease the ability of the Aqua-Barrier to perform as projected.
Pipeline installation and repairing
Pipeline repair or replacement projects can be complex particularly when water is present. We understand that pipeline repairs often require completion in a short time frame. Aqua-Barriers provide the fastest cofferdam method available. The next time that you are confronted with a temporary cofferdam need, let us save you time and money.
A complete enclosure formation is beneficial when access to the shoreline is difficult or when a large amount of linear footage is required to reach your work area in the water.
The partial block formations is advantageous when projects are located in moving water, and it is not feasible to use a pipe diversion or a water pump to maintain upstream water levels.
The canal block formation is beneficial when working in narrow channels because the system requires only one installation and removal. Water pumps can be utilized to maintain appropriate upstream water levels.
Boat ramp installation
Boat ramp construction often provides unique challenges, because it is necessary to remove the existing water prior to installing the ramp. Aqua-Barriers provide a cost effective temporary dam for this type of project.
A three sided formation is utilized when the shoreline is straight and ample work area is required.
The tee-pee design is beneficial when the shoreline is curved and a large work area is not necessary.
A straight shoreline formation is preferred when work area is located in a recessed cove.
Bridge construction
When a bridge is needed, water is usually the cause. Our Aqua-Barrier system can be used in a number of ways to facilitate your cofferdam requirements. Whether it is creating a dry working environment by completely diverting the waterway or by diverting water around individual piers, Hydro-Solutions can help you solve your dewatering needs.

A complete enclosure formation is beneficial when access to the shoreline is difficult or when a large amount of linear footage is required to reach the work area in the water.
The canal block formation is useful when working in narrow streams because the system requires only one installation and removal. A diversion pipe can be utilized to maintain appropriate upstream water levels.
Shoreline stabilization
When shoreline restoration projects require dewatering or even turbidity control, the Aqua-Barrier can provide a cost effective alternative to conventional products. The versatility of the Aqua-Barrier affords the option of dewatering the entire shoreline area or moving the system in stages.
The entire shoreline enclosure design is useful when only one installation and removal is required in the work area.
A multiple staging configuration is advantageous when the scope of the work involves a large expanse of shoreline because the barriers can be installed and removed in short order.
Culvert installation and repairing
Culvert construction can be troublesome if water is present in the work area. The Aqua-Barrier will adapt to a variety of different environments, providing the most cost effective solution for your temporary dam requirements.
A three sided formation is utilized when the shoreline is straight and a large work area is required. An inflatable pipe plug is also installed in the opposite end of the culvert to prevent the water from infiltrating the work area.
The canal block formation is beneficial when working in narrow channels because the system requires only one installation and removal. Water pumps can be utilized to maintain appropriate upstream water levels.
Other projects
Dewatering projects come in all shapes and sizes. Aqua-Barriers provide a multi-purpose solution to your temporary dam requirements.
Save time: Aqua-Barriers are installed and removed more rapidly than conventional cofferdam methods saving both time and money. Simply inflate the Aqua-Barrier with any available water source. Upon project completion, drain the barriers for prompt removal.
Environmentally compliant: Aqua-Barriers meet or exceed even the most stringent environmental agency’s water quality restrictions. Unlike conventional cofferdam methods, the environmental impact is greatly reduced. The system uses the existing water for inflation and the barriers are completely removed upon project completion.
Engineered for safety: Extensive engineering went into the design of Aqua-Barriers culminating in our exclusive patented inner baffle system. The result is a water control system that is safe, stable and effective.
