Geosynthetic portable cofferdams for civil construction applications

August 1, 2021  |  Features

Cofferdams are an enclosure built within or across a body of water to allow the enclosed area to be dewatered. This creates a dry working environment so construction can be carried out properly and safely. Typical cofferdams are welded-steel structures consisting of sheet piles, wales or cross brace…
