This project involved installation of 3 watertight caisson wall shafts. Two rectangular secant pile wall shaft approx 12m deep and one 6m diameter compression ring shaft approx 7m deep. In order to achieve the tight tolerance needed to ensure the shafts were in fact watertight the use of a guide wall was implemented. The guide wall was installed using Styrofoam form and concrete to allow drill casing to be perfectly centered over the drilled holes.
