Find more details about our solutions to transfer loads down to bearing strata and decrease construction times and residual settlements in compressible soils. Some of these techniques can also be used to mitigate the risk of liquefaction.
Peaty, clayey and sometimes even silty soils are characterized by a high-water content, very low permeability and a low strength. When loads are applied to these soils, excess pore water pressure develops as the soil cannot adjust to the new load due to the very low permeability and slow dissipation of the excess pore water.
When an embankment needs to be constructed with no time available for the dissipation of the excess pore water pressure by means of our consolidation techniques, so called elements are often used as ground improvement solution. All element solutions have their own characteristics, but the main principle is load transfer down to the bearing strata. In case of GEC and CSC technique combined with limiting the development of excess pore pressures and thus also reducing the residual settlements after construction.
Stone columns and GEC’s can also be used to mitigate liquefaction.
