Manufacturer Supply Inflatable Rubber Dam to Pakistan

Water Filling Rubber Dam

1. Product Introduction
Rubber dam is long tubular-shaped fabrics placed across channels, streams and weir crest to raise the upstream water level when inflated. The membrane is a multi-layer fabric made of synthetic fibre which may be rubberized on one or both sides, and possibly coated with plastic film. The fabric is quite flexible and yet exhibits very large resistance characteristics. In open channels, they are used to divert water for irrigation, for raising existing dams, for flood control ling. Other applications include remedy measure to prevent dam overtopping and control of chemical spills in streams.
