Instant Underflow and Instant Coffer Dams - How to Join Units Together

Installs in minutes, with only 2 or 3 people.
Flexible material allows it to adapt to most stream and ditch bottoms.
No special equipment is needed. No filling with water or inflating with air is needed. Simply unroll the dam, unfold the upstream flap and let the flow of the stream fill it.
No anchoring is needed. Just use the weight of the water to weigh it down to the stream bottom.
Underflow holes are built into the downstream side so that you can regulate the flow on the upstream side and keep the spill contained.
Multiple units can be attached together to make whatever length you need.
Wash and reuse dozens of times.
