Groundwater Cutoff Wall

• Can be designed to completely cut off groundwater into the excavation without a natural aquitard.

• Batter freeze pipe can be installed at any angle to accommodate site space constraints.

• Can be modified: vertical pipes on one side and batter pipes on the other side.

• Uplift is controlled by freezing deeper than the excavation depth.

• Very cost-effective shoring method when contaminated groundwater is present.

• Can be effectively used to depths of 40 feet or more.
