Groundwater Cutoff Wall

• Circular-shape frozen soil wall provides very strong shoring without internal bracing.

• Has been used on hundreds of shafts worldwide to depths of 800 feet.

• Completely cuts off ground water to eliminate dewatering.

• Generally costs less than other deep shaft methods (secant concrete piles, jet grouting, etc.).

• A frozen soil seal can be created at sites where no natural groundwater cutoff is present.

• May be used in nearly all soil and groundwater conditions.

• Designed to resist uplift without expensive tie-downs.
