FAQ
Cofferdams offer several benefits, such as creating a dry and stable work environment, facilitating safe and efficient construction below the waterline, reducing project timelines by eliminating water-related delays, minimising environmental impact by controlling water flow and sedimentation, and providing cost-effective solutions for water-based construction challenges.
Cofferdams are typically built using steel sheet piles driven into the ground to form a watertight enclosure. The enclosed area is then dewatered to provide a dry workspace. Depending on the project, additional support structures like bracing or struts may be used to ensure stability. You can learn more about that in our blog.
A cofferdam is a temporary structure designed to hold back water to create a dry working area. A retaining wall, on the other hand, is typically a permanent structure used to support soil or rock to prevent erosion or landslides. While both provide support, their functions and longevity differ.
Yes, cofferdams are commonly used in marine construction projects, such as building harbours, piers, or quay walls. They provide a dry work area in water, enabling efficient construction of underwater structures
The cost of a cofferdam depends on factors such as the size of the enclosure, the depth of water, soil conditions, and the materials used. Other cost considerations include the complexity of installation, dewatering systems, and the length of time the cofferdam will be in place.
