Secant Walls



Secant pile walls are used in situations where a palisade/soldier wall is not sufficient due to ground conditions, and a continuous pile wall is required.

Constructed with a method of using a softer concrete pile overlapped by a reinforced concrete pile leaving a waterproof underground wall that can be excavated against.

The secant pile wall method provides a cost effective solution for the construction of deep excavations to form basements, cut and cover tunnels, tanks, etc.
