Transform Your Approach to Water Management with
Aqua-Barrier®
The ultimate solution for temporary damming and flood protection.

The company also reports that installation can be three to five times faster than traditional damming methods, depending on project conditions.

Aqua-Barriers are reusable and repairable, giving contractors an alternative to temporary systems that require large quantities of imported fill or disposable materials. HSI reports that, with proper care and use, its barriers can typically be reused 15 to 20 times.

Effortlessly streamline installation and positioning: The self-stabilizing Aqua-Barrier® utilizes the water’s weight to securely anchor itself, eliminating the requirement for extra hardware or ground penetration.

The Aqua-Barrier®’s flexible structure significantly lowers the risk of injuries compared to traditional sandbags and concrete barriers. The simple deployment and removal processes reduce exposure to hazardous conditions, guaranteeing a safe and dry environment.

The non-erodible Aqua-Barrier® significantly reduces waste and erosion – compared to single-use sandbags and intrusive sheet piling – contributing to environmental sustainability. Its deployment causes minimal disturbance to the natural landscape, preserving soil integrity and local flora and wildlife while ensuring a safer and eco-friendly solution for controlling water.
How Aqua-Barrier® helps with Water Management
The Aqua-Barrier® is HSI’s patented water-inflated cofferdam system, designed to provide temporary water control without many of the materials and site impacts associated with conventional methods such as sandbags and earthen dams.
At the heart of the Aqua-Barrier is its patented internal restraint system. The baffles help stabilize the water-filled barrier under hydrostatic pressure, allowing the system to create a dependable temporary barrier for a range of water-control applications.
- Construction dewatering: Creating dry work areas for bridge, culvert, shoreline, intake, outfall and other in-water construction and maintenance projects.
- Pipeline and infrastructure work: Temporarily isolating work zones for installation, inspection, maintenance and repair.
- Flood protection: Creating temporary barriers to help protect properties, facilities, infrastructure and other assets from rising water.
- Temporary water control and storage: Managing or containing water when projects require a flexible temporary solution.
Our system heights vary from 2ft up to 8ft and can control up to 6ft of water and sediment depth combined.

Our system heights vary from 2ft up to 8ft and can control up to 6ft of water and sediment depth combined.
Our water-inflated temporary cofferdams consist of the following:
The Aqua-Barrier is a self contained, single tube with an inner restraint baffle(s) stabilization system. The water-inflated dam has the ability to stand alone, without any additional external, mechanical, or gravitational stabilization devices.
The water-inflated dam is produced from a heavy gauge polyvinyl chloride (PVC) reinforced with polyester. The PVC fabric used to create the inflatable dam is in-field repairable utilizing a vinyl adhesive and patch material, the PVC fabric used to create the inflatable dam’s outer membrane is able to be repaired in-field, wet or dry.
The water-inflated dam is equipped with patented pipe-loops on both ends, which allow you to maneuver the system with heavy equipment during installation and removal, ultimately minimizing the manual labor involvement.
The method for connecting individual units together consists of simply overlapping the ends of the barriers, at any angle, which creates a watertight connection. No other devices or methods for connecting the barriers are neccessary.
Our 4in and 8in ports are equipped with floatable caps, ensuring easy retrieval and deployment during water management operations. Additionally, all caps feature female threading with National Pipe Thread (NPT), enhancing convenience during barrier usage.
