Big Bags USA construction barrier systems have unmatched versatility to handle the highest demands at a fraction of the costs compared to other products The One Ton Bag™ is an ideal product to build a cofferdam or temporary enclosure, within a body of water.Once the enclosure is constructed, water can be pumped out, creating a dry work area. The One Ton Bag™ can be submerged around various bridge piers, creating spaces that can be pumped free of water to provide workers with dry areas to carry out masonry repairs below the water line A cofferdam is a temporary dike built across a body of water, and constructed to allow the water to be pumped out of the enclosed area. Cofferdams are used in order to allow for a dry working environment. Once a cofferdam is in place, crews are able to do things like excavation, repairs, and pouring concrete. Jump to For nearly four decades, Portadam has been utilized as an effective temporary cofferdam solution providing contractors a dry work condition while saving both time and money. Traditional cofferdam and water diversion approaches are often specified to allow the work to take place in the dry, but these can be very cumbersome - from a cost. A temporary cofferdam is a modern implementation of a water barrier. Today's temporary water barriers are primarily used to hold back flood waters or to provide a dry environment for construction projects. Examples of temporary water barriers are cofferdams, sandbags, and earthen berms but there are also permanent water barriers that include.

The Need for Water-Filled Cofferdams in Construction. A cofferdam is a structure, usually temporary, used to isolate a submerged work area — either to contain turbidity or allow for dewatering of the underwater construction area.
