Wet vibro stone columns using the support of water to penetrate the soil during penetration to the design depth.
are inclusions of a granular material which are formed in the ground, improving the load bearing capacity and limiting both total and differential settlement.
Stone columns can be installed in groups under isolated loads or directly under linear loads such as strip footings. Columns can also be arranged in a grid pattern to provide support to uniformly loaded structures such as ground ﬂoor slabs and embankments.
Stone columns are suitable for the improvement of both weak natural soils and made ground with typical improved bearing capacities ranging from: 50kN/m2 to 150kN/m2.
