Technical Details

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 can be used to resist significant compressive, uplift, and lateral loads.  Bored piles can be drilled to depths in excess of 60m and typical diameters range up to 2.4m.
