With a seasoned team of skilled divers and state-of-the-art equipment, we specialize in providing comprehensive cofferdam solutions for a wide range of underwater projects.

Custom Cofferdam Solutions Built for Safety & Performance

Cofferdams are an essential part of dam construction, and at VTS, we have experience in installing many types and sizes of temporary structures. From robust cellular cofferdams to cost effective Portadam™ systems, we have the expertise to find a solution to fit any project. We have a full service fabrication shop and can create customized cofferdams that will optimize efficiency and safety.

Safety is paramount when working with cofferdams. There are many risks involved in installing and maintaining an effective cofferdam such as ice flows, current, vessel traffic, rock fissures, flood events, soil conditions and more. When working inside, crews are often in confined space conditions, requiring atmospheric monitoring and emergency response plans. At VTS, we are familiar with both large scale cofferdams such as cellular structures as well as small cofferdams such as box-type, and will create an effective safety plan for each individual project.
