Cofferdams are temporary structures built around a construction site that is submerged in water, such as in a river, canal or lake. For over two decades, Geodesign Barriers have proven to be an effective solution for building these temporary structures. Scroll down to discover the benefits and applications of Geodesign Barriers for cofferdams.
When faced with challenging sites, where pre-made and traditional 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 dry, while reducing site risk and preventing unforeseen delays. With their flexible design, Geodesign Barriers can easily be applied to any layout and stand up to even the strongest water flow and tides.
Geodesign Barriers are the perfect environmental solution, as they leave the subsurface undisturbed and minimise 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.
Geodesign Barriers offer a more efficient and cost-effective solution for temporary cofferdam and water diversion needs than sheet piling. Their modular design allows for quick assembly and disassembly without requiring heavy machinery or extensive site preparation.
Geodesign Barriers is a modular flood barrier system that is easy to assemble in the water with minimal manpower and without heavy machinery or extensive groundworks. Its modular design allows for flexibility and adaptability to different project requirements and configurations.
By using a cofferdam system that does not require ground penetration, construction projects can reduce environmental risks and costs while improving efficiency. The Geodesign Barriers solution offers this advantage and more. In addition to eliminating the need for ground penetration, it also minimises the dewatering of excavated material, making the project more sustainable and eco-friendly.
This modular cofferdam system is designed to be easily customised into almost any shape. Its portable and effective design utilises the weight of the water to create a water-tight seal, making it an ideal solution for various cofferdam projects that require flexibility in shape and design. Its versatility and adaptability make it an efficient and cost-effective option.

Installing Geodesign Barriers in water is a straightforward process. First, the metal supports are unfolded into a triangular shape on land and then secured into their upright position, with the simple snap-lock mounted on the supporting beam. Once in the water, the supports are linked together with connection bars. Finally, aluminium sheets or specially designed cofferdam elements are placed on the bars.
On land, a chain is embedded into the outer edge of the plastic membrane and secured. After the metal structure of the Geodesign Barriers has been installed in the water, the membrane is laid out on the water and attached to the top edge of the barrier. With the barrier placed in the water, the membrane is pressing down against the barrier and the river- or lake bed. This completes the second step in the installation process and sets the scene for the next step, which can be started simultaneously.
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 creates a dry work area or isolates a water-filled area.
Geodesign Barriers are modular cofferdam systems that can be quickly assembled and disassembled, providing a flexible and cost-effective solution for a wide range of water-related construction projects. Here are some examples of how Geodesign Barriers could be used in different situations where a cofferdam may be needed:
Geodesign Barriers can be used to create a dry work area around bridge piers or abutments, allowing work to be safely carried out without being hindered by water. The modular design of Geodesign Barriers allows them to be quickly assembled and disassembled, making them an ideal solution for bridge construction projects that require multiple cofferdams to be erected and dismantled quickly.
Cofferdams are often used during the construction of dams to divert water flow and create a dry work area. Geodesign Barriers can be used in place of traditional cofferdams, providing a more flexible and cost-effective solution. The modular design of Geodesign Barriers makes them easy to transport and assemble, allowing for quick deployment and efficient use of resources.
Geodesign Barriers can be used to create a dry work area for welding or installing pipes during pipeline construction in water bodies. The modular design of Geodesign Barriers makes them easy to install and remove, reducing the time and cost required to complete the project.
Geodesign Barriers can be used to isolate and repair water infrastructure such as dams, locks, and water treatment plants. The modular design of Geodesign Barriers allows them to be customized to fit the specific needs of each project, making them an ideal solution for infrastructure repair and maintenance projects.
Geodesign Barriers can be used to create a dry work area around ships, allowing for repair- and maintenance work on the ship's hull to be carried out without the interference of water. The modular design of Geodesign Barriers makes them easy to transport and assemble, making them an ideal solution for ship repair projects that require multiple cofferdams to be erected and dismantled quickly.
Geodesign Barriers can be used to isolate and contain contaminated soil or water during environmental remediation projects, allowing for the safe removal and disposal of hazardous materials. The modular design of Geodesign Barriers allows them to be easily customized to fit the specific needs of each project, providing a flexible and cost-effective solution for environmental remediation projects.
Geodesign Barriers provide a fast and efficient solution for boat ramp maintenance and construction. Their modular design allows for quick assembly and disassembly, reducing time and cost. They create a dry and safe work environment for repairing, expanding, or constructing boat ramps. With Geodesign Barriers, projects can be completed quickly, safely, and effectively.
Use a temporary cofferdam construction to block the water in a canal and extend the retention pond's water fountain. Geodesign Barriers' cofferdams keep workers dry and prevent flooding, protecting personnel and equipment.
Geodesign Barriers provide a flexible and cost-effective solution for shoreline restoration and stabilisation projects. By using cofferdams, Geodesign Barriers can serve as a barrier between the beachfront and water, preventing deterioration and erosion. The modular design of Geodesign Barriers makes them easy to install and remove, reducing time and cost.
