Ground improvement is vital for soil layers with insufficient bearing capacity and with a high risk of settlements. At Dieseko Group we offer a wide range of equipment to allow for multiple different ground improvement methods.
We offer an array of ground improvement techniques with the goals of drainage, compaction and replacement.
Drainage
Through the use of vertical drains, pore water can be removed from soft soils with low permeability in order to speed up the soil settling process. These vertical drains can be placed using a winch driven rod, or by using a vibratory hammer in instances of stiffer or denser soil layers.
Compaction
Under influence of induced vibrations, soil particles are rearranged to become more dense and compacted.
Replacement (sand, grout and stone columns)
During replacement, a different kind of soil or gravel sized stone particles are introduced into the ground to increase stability and preformance of soft or loose soils. There are many ways to do this, for example by using the Vibratory Hammer with tubes or a Drilling Rig to create stone columns which increase bearing capacity, reduce foundation settlements, improve slope stability, reduce seismic subsidence, reduce lateral spreading and liquefaction potential, and permit construction on loose soft fills.
Grout, sand- and stone columns can also be created by drilling, driving and vibrating a thick walled steel casing into the soil. After the required depth has been reached by the casing, a geotextile bag is placed inside it and the casing is filled with sand or granular material creating columns. The casiing is then extracted.
