Our Cofferdam Technology
A portable cofferdam is any pre-fabricated water barrier that can be transported to and installed at a project site, oftentimes in response to an emergency rising water level situation, like a flood or the need for drier work environments. Cofferdams offer a reliable solution to many water damming or diversion necessities in the construction industry, as well as homes and businesses that need flood protection.
What Is a Cofferdam System02
How Our Cofferdams Work
Our water inflated cofferdams use on-site water filled dual inner tubes that allow the dam’s chambers to slowly and evenly inflate, forming a strong, stable cylindrical barrier. As the inner tubes fill and water pressure builds, the dam unrolls in a controlled and steady manner to create the cofferdam and provide an even and gradual build to make it more secure. This method offers a superior barrier as compared to sandbags, which are often ill-equipped to handle large amounts of water or flood walls which create a long-term barrier that alters the aesthetic of a home or business from its original intended appearance.
See How It Works03
Environmentally Superior Water Filled Dams (Cofferdams)
Because our inflatable cofferdams work with the environment, they create effective water barriers that leave minimal or even no footprint on the environment. When the project is completed, the dam is then easily drained and rolled up for return, storage, or transport to another project site. They also don’t require the relocation of earthen-fill from another site or location in order to provide the safe and secure environment you and your crew should absolutely expect of a water barrier. In addition, their ability to be re-used, as well as their durability against oftentimes destructive conditions, means they’re less likely to become a burden that sits in a landfill somewhere instead of the handy and necessary tool and companion it’s intended to be.
