Ground Stabilisation for a London Developer
The Developer had a requirement to increase the existing buildings height to create an apartment complex, however, due to the underlaying soils ground bearing capacity not being suitable, a geopolymer solution was developed and designed in collaboration with the client’s structural engineer to facilitate the build. The required ground bearing capacity for ground was 100 KN/m2 which required materials to be blended and mixed to meet the required strength.
The works involved driving injection lances 2.5 meters below the perimeter foundations and internal foundations. Once installed, the injection lances were injected with a structural polyurethane ground stabilisation geopolymer resin. During the process the injection lances were extracted at 150mm increments to guarantee continuous placement of the geopolymer.
