Abstract

A flexible body in the form of a strip of elastomeric material, has a slit through it thickness reaching from one edge to a predetermined point across its width, and extending lengthways through the strip. The strip can be anchored to a river bed, bank or beach by fastenings which close the split so that the strip can be inflated by injecting fluid to form a dam. The elastomeric material may be reinforced by woven fabric cut on the bias, and one or more auxiliary chambers of smaller dia. than the cavity formed in the strip may be provided inside the inflatable chamber and run along its length. The new design is a marked improvement on dams formed by simply folding over a strip of elastic material, since when the sam is deflated, the folded edge is very easily damaged.
