Is your way of damming up streams complicated, time-consuming, and expensive?
Do all of your supplies take up extremely too much space and weight tons and tons?
Problem #1: Traditional cofferdams require a lot of time and equipment.
- Time to fill and deploy sandbags.
- Manpower or equipment to lift and place sandbags.
- Time to prepare the streambed.
- Time and pumps required to fill water-filled barriers.
- Time to redeploy in case of a “blow out.”
Problem #2: Traditional cofferdams are expensive.
- Shipping costs to get large, bulky sandbags to site.
- Labor costs to fill and deploy sandbags.
- Fuel costs to keep the pumps and equipment running.
- Cost of delaying the job hours or days to set up.
- Cost being “washed out” and needing to be rebuilt.
Building a cofferdam should not be complicated.
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.
