Keller provided a low vibration fully displacement solution for a new single-storey fast food restaurant on a site where there was a danger of forming a pathway to contaminate an aquifer below the surface. The solution also delivered a lower carbon alternative to driven piling.
Challenge
The main challenge was to provide a solution through the very low-strength strata of the Tidal Flat Deposits while avoiding the formation of a pathway for contamination to the aquifer below.
Solution
Rigid inclusions were installed for the foundations to achieve the required bearing capacities of 100kN/m2 for the foundations and 20kN/m2 for the floor slabs.
A fully displacement cast in-situ installation method was employed to minimise the environmental impact of the works and secure the acceptance of the Environment Agency.
Keller's proposals also offered the client significant time-savings over a precast piling option as the foundations could be excavated while the concrete was fresh, and a ground bearing slab could be cast onto the surface of the treated soils.
