Project Description: River diversion to repair a main pipeline.
Creating a dry work site along a riverbank does not always require damming. River diversion using a cofferdam while the project is underway is oftentimes best.
Dam-It Dams cofferdams use on-site water for inflation. As the dam fills, it can be molded to perfectly fit the river bed and riverbank, which provides an excellent seal.
Our cofferdams are readily available in sizes ranging from 1′ to 12′ high and 2′ to 23′ wide. Standard lengths are 50′ and 100′, although any length can be accommodated by connecting multiple cofferdams.
There are as many water-control applications for cofferdams as there are types of cofferdams. Dam-It Dams’ patented, portable, water-filled Cofferdams offer effective and cost-efficient solutions for these major types of situations that are called the 3-Ds of water control:
Dewatering, unwatering and water control are common terms used to describe the removal or drainage of ground or surface water, typically on a construction site. This technique is often required before subsurface excavation for such things as foundations, shoring, cellar space and repairs to existing water structures. As a result, a cost effective solution is necessary to keep the project moving. That’s where we can help.
Diversion is the temporary (or sometimes permanent) re-routing of water. It may be required to initiate a project and/or allow a project to proceed.
Damming is the process of creating a barrier that holds back water. The barrier may be needed to maintain water table levels, collect water for storage and prevent water from crossing established/safety thresholds.
Because Dam-It Dams’ Cofferdams work with Mother Nature, not against her, they create effective water barriers that leave no – or only a minimal – footprint on the environment. Furthermore, our cofferdams are industrial strength and reusable to minimize additional investment costs.
