Groundwater Cutoff Wall

• Cuts off groundwater along sides and bottom to eliminate dewatering.

• Provides stable shoring with no internal bracing or struts.

• Batter freeze pipe can be used to allow heavy construction traffic along the top of the wall.

• Bottom concrete seal can usually be eliminated.

• Appropriate for excavations up to about 40 feet deep.

• Cost-competitive compared to conventional shoring (sheet piles, soldier pile walls).
