Description

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.

  1. Installs in minutes with minimal manpower.
  2. Flexible material allows it to adapt to most stream and river bottoms.
  3. 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.
  4. No anchoring needed. Just uses the weight of the water to weigh it down to the stream bottom.
  5. Multiple units can be attached to make whatever length you need.
  6. Wash and reuse dozens of times.
