Discover the power of secant and tangent pile walls, integral components of Schnabel’s rigid and robust system for earth retention and groundwater cut-off. Our construction process involves drilling alternating primary and secondary overlapping shafts, forming continuous secant walls. Concrete in the shafts can vary in strength, with options for low-strength primary and high-strength secondary shafts, reinforced with steel piles, or reinforcing steel.
Tangent piles offer a touching configuration without overlapping. Experience the impermeability of secant pile walls, controlling groundwater flow and minimizing drawdown outside excavations, while providing exceptional stiffness to protect sensitive structures.
Benefit from Schnabel’s advanced high torque drill rigs, capable of penetrating hard-drilling conditions and casing the drill hole simultaneously. Trust our expertise in navigating obstacles like cobbles, boulders, and reinforced concrete for efficient cutoff wall construction.
