Flood Barriers and Construction Dewatering

boat ramp installationA cofferdam is a temporary structure extensively utilized in construction, primarily for two key purposes: dewatering and flood protection. In construction, cofferdams are deployed to create dry, controlled workspaces within submerged or waterlogged areas. They play a crucial role in projects like bridge construction, pipeline installation, and foundation building by excluding water and enabling safe and efficient work.

Additionally, cofferdams serve as an essential tool for flood protection, effectively stemming the ingress of rising floodwaters to safeguard properties, infrastructure, and communities from potential damage and deluge during flood events.
