Drilled shafts, also known as caissons, are high-capacity, cast-in-place elements constructed using an auger. Whether as isolated columns or a secant/tangent wall, Hayward Baker is ready to provide you with the optimized drilled shaft solution.
- Provide structural support
- Provide earth retention
A hole with the design diameter of the planned shaft is first drilled to the design depth. If the hole requires support to remain open, casing or drilling fluid is used. Full-length reinforcing steel is then lowered into the hole which is then filled with concrete. The finished foundation element resists compressive, uplift, and lateral loads.
