Cofferdam Sizes: 8′ high x 100′ long
Water Depth: 5-6′
Installation Time: 8 hours
Project Description: A Dam-It Dams cofferdam was used to temporarily block water flow in a river to allow installation of a new 36″ gas main.
Spanning a river above or below water often requires a dry work environment. The length of the span, water depth and flow intensity are key determinants of equipment needed. Dam-It Dams cofferdams are designed to fill that equipment need.
Our cofferdams are expandable to 1,000′ feet or more, can hold back water up to 8′ and withstand tremendous flow pressure because they use their water-filled capability to counteract the opposing flow.
