Cofferdams-Hero

Revolutionizing Waterfronts with Geodesign's Robust Cofferdams

Cofferdams are temporary structures built around a construction site that is submerged in water, such as in a river or lake. For over two decades, Geodesign Barriers have proven to be an effective solution for building these temporary structures.

Site-Specific Cofferdams: Reliable for Complex Projects

When faced with challenging sites, where pre-made dams just won't cut it, Geodesign Barriers provides the perfect solution with their site-specific cofferdams. These temporary dams are carefully engineered to adapt to the unique conditions of your project and guarantee to keep the area high and dry, while reducing site risk and preventing unforeseen delays. With an overall design that is flexible, Geodesign Barriers can easily be applied to any layout and are impenetrable to even the strongest water flow and tides.

Geodesign Barriers are the perfect environmental solution, as they leave the subsurface undisturbed and minimize the impact on the surrounding environment. So, whether you're dealing with a particularly challenging site or looking for an eco-friendly solution, Geodesign Barriers' cofferdams are the ideal solution.

Step 1. Unfold and place the barrier supports in water.

Installing Geodesign Barriers in water is a straightforward process. First, the metal supports are folded up into a triangular shape on land and fixed into an upright position with the simple snap-lock mounted on the supporting beam. Once in the water, the supports are linked together with link bars. Finally, aluminum sheets or specially designed cofferdam elements are placed on the link bars, depending on the specific needs of the project.

Step 2. Attaching the Membrane in Water

After the metal structure of the Geodesign Barriers is installed, the plastic membrane is laid out on the water and attached at the top edge of the barrier. On land, a chain is rolled into the membrane and attached. When the barrier is placed in the water, the membrane is pressed down against the barrier and bottom. This completes the second step in the installation process and sets the foundation for the next step, which can be started simultaneously.

Step 3. Pumping out water.

Once the plastic membrane is in place on the Geodesign Barriers, it's time to start pumping out the water. As the water level drops, a pressure difference is created between the embankment and the remaining water. This pressure difference causes the membrane to press against the barrier, creating a watertight seal. The water pressure pushing against the barrier also creates an anchoring force, which causes the system to self-anchor. This third and final step in the installation process sets the foundation for a reliable and effective solution that create a dry work area or isolate a water-filled area.
