Tangent Pile Wall Construction Solutions
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.
When challenging drilling conditions loom, secant and tangent piles present economical solutions for cutoff wall construction. Schnabel’s expertise extends to secant walls, offering cost-effective alternatives to slurry walls and soil mix walls.

Barnes-Jewish Hospital
Schnabel designed and constructed a secant pile wall for the Barnes-Jewish Hospital Parkview Tower on the Washington University Medical Campus in St. Louis, Missouri. The perimeter secant wall served as both the permanent structural basement wall and the temporary earth-retention system for the new hospital building.
In 31 years of building deep foundation projects for Schnabel, building a 90’ deep reinforced circular shaft was one that was very challenging and deeply rewarding. Looking forward to working on the next one with our client Schiavone.
