Stingray Self-Deploying Water Dam is a flexible yet effective flood dam used to stop and hold back water. As water accumulates inside the dam pocket chambers, it ballasts the bottom of the fabric; combined with the traction strips on the underside, the water dam stays in place.

The Stingray™ Self-Deploying Water Dam is made from flexible PVC material allowing it to conform to nearly any surface, as well as be deployed on varying sub-surfaces within the same area. Stingray is a long term water dam solution that is designed with reusability and ease of deployment as a priority.
