CLL completed Stone Columns for Ryman Healthcare, Petone, Wellington . CLL completed a total of 12,625 stone columns for buildings 01 and 02 in this development. Stone columns work by piercing the weak soils by vibration and jetting, this creates a hole to the designated depth. After being held at the depth for a short amount of time the probe is taken out and a charge of stone is positioned in to the hole. The probe is then put back into the hole, and the stone is forced into the ground and compacted down for strength. By then adding successive charges of stone and compacting, the column of dense compacted stone is built up to ground level.

CLL are completed the sheet piles as well as Stone Columns. CLL completed 1,380 sheets for the sheet piles throughout buildings 01 and 02 for the development. These sheet piles are constructed by driving prefabricated sections into the ground. Soil conditions may allow for the sections to be vibrated into ground instead of them being hammer driven. The full wall is formed by connecting the joints of adjacent sheet pile sections in sequential installation. Sheet pile walls provide structural resistance by utilizing the full section. Steel sheet piles are most commonly used in deep excavations, although reinforced concrete sheet piles have also being used successfully.

CLL has successfully been awarded the next stage of this development.
