Maintain Water Flow with Aqua-Barrier® Using Diversion Pipes

Maintain Water Flow with Aqua-Barrier® Using Diversion Pipes

While a dry worksite is essential for many construction and repair projects, there are many cases where it is not feasible to completely cut off the water flow. In applications that require the water flow of a river or creek to be completely cut off, it may become necessary to maintain water flow using diversion pipes or bypass pumps.

The Water-Inflated Cofferdam: A Dewatering Solution For Many Industries

If you work in an industry where you must do construction or repairs under water, an Aqua-Barrier® water-inflated cofferdam can make a world of difference in your projects.

Sandbags may be your current go-to dewatering solution, but once you’ve tried an Aqua-Barrier® water-inflated cofferdam, you will never go back!

Aqua-Barrier® cofferdams are customizable, repairable, and reusable. You can also feel good knowing that your dewatering solution will leave no environmental footprint – unlike sandbags which require Hazmat procedures for disposal.

What’s more, the Aqua-Barrier® Cofferdam System is easily portable from one worksite to the other, which can reduce valuable time between jobs and allow you to be more competitive in bidding for your next project.

Our water-inflated cofferdam system has been used in many industries all over the world to keep worksites dry. Here are just a few areas that have benefited from its innovative design:

Boat Ramp Using Water-Inflated Cofferdam

Boat Ramp Construction

Contractors love this system for installing boat ramps because it comes in many sizes, can be adjusted to meet your specific needs, and can be installed quickly to give them an edge up on competing bidders.

Bridge and Dam Construction

The Aqua-Barrier® has proven to be a time and cost effective solution for bridge and dam construction. A 100-foot barrier is available for large rivers, oceans, and lakes. Or, we can create a customized package specifically for your project.  

Concrete Repairs

When concrete in a high-water area begins to crack and need repairs, you need a quick and easy solution for drying out the worksite to get the job done. An Aqua-Barrier® cofferdam is a great solution for canals and culverts. They can be effortlessly installed, allowing you to focus your time and energy on the project at hand.

When water surrounds underground pipelines and utility lines, it can be difficult to complete repairs. Our environmentally friendly cofferdam creates a barrier around the pipes so you can fix, install or repair them.

Shoreline Restoration

Shorelines have restoration needs, but it can become troublesome due to its location up against masses of water. Using sandbags become messy and water still seeps through. Using our Aqua-Barrier cofferdams will prevent and maintain seepage so the work site is dry, and you can more effectively restore the shoreline. Because it comes in up to 100 feet in length and 8 feet high, it’s great for large areas needing a dewatering solution.

Hydrological Solutions Success Story: Tri-State Utilities Aqua Barrier Project

Hydrological Solutions Success Story: Tri-State Utilities Aqua Barrier Project

Hydrological Solutions was proud to service Tri State Utilities with our Aqua Barrier Cofferdam.  Tri State Utilities is located in Virginia.  They specialize in commercial trench-less pipe repairs and storm drain cleaning.  Since 1996, Hydrological Solutions has been providing companies the cofferdams they need to keep emergency storm protection systems in order. Our aqua barriers proved to be an important asset in the dewatering of Tri State Utilities work site.

This project specified the need to provide an aqua barrier for water that was six feet in depth. We provided Tri State Utilities with two Aqua-Barriers that inflated to eight feet in height and fifty feet in length. Steven A. McSweeney, President of Tri State Utilities, said he was very pleased with Hydrological Solutions. “Service was flawless and the product worked perfectly,” said McSweeney. The two Aqua-Barriers blocked the water in a stream into which the storm drain fed. By creating a clear, dry work site, the coffer dam allowed Tri State Utilities to repair the storm drains in a timely, safe manner.

Cofferdam AnatomyBased out of Texas, Hydrological Solutions consistently services the entire country and beyond.  The Aqua-Barrier’s innovated internal baffle design continues to be the gold standard in the construction industry for water inflated dams.
