The Instant Cofferdam is designed to be simple, fast and cost-effective.
- Installs in minutes with minimal manpower.
- Flexible material allows it to adapt to most stream and river bottoms.
- No special equipment needed. No filling with water or inflating with air required. Simply unroll the dam, unfold the upstream flap and let the flow of the stream fill it.
- No anchoring needed. Just uses the weight of the water to weigh it down to the stream bottom.
- Multiple units can be attached to make whatever length you need.
- Wash and reuse dozens of times.
