Groundwater Cutoff Wall

• Allows large, shallow excavations to be accomplished in the "dry" with no dewatering.

• Freeze pipes are installed nearly horizontal using directional drilling methods.

• Completely seals the site from groundwater.

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

• Adapts to sites of variable size and shape with lengths up to 1,000 feet.

• Can also be used to cut off groundwater beneath existing structures.

• Cost effective to depths of 60 feet or more.
