Location: Hancock , NY
Cofferdam Sizes: Two 4′ high x 100′ long
Water Depth: 3′
Installation Time: 4 hours
Project Description: Install a new 36-inch gas main on a tributary to the Delaware River.
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.
