One step includes installing a secant pile wall into the earth. The secant pile wall encloses a portion of the earth. Another step includes excavating the portion of the earth enclosed by the secant pile wall.

And yet another step includes partially or more filling a space located between the inside surface of the secant pile wall and the metal liner with a grout material.
