TSM expertly stabilised ground beneath a Grade II listed Westminster site using polymer injection. This vibration-free, eco-safe method ensured excavation safety near sensitive structures, maintained strict tolerances, and minimized disruption in a high-security, heritage setting.
The conservatory/ extension was suffering from subsidence with a detaching effect away from the main structure of the house.
The concrete bund was deemed an environmental concern as containment could not be assured due to the level of deterioration of the concrete elements of the bund and sealant joints due to chemical exposure and general environmental degradation.
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 client had a requirement to consolidate and fill voids to the ground at the back of the piled wall, which was identified due to the movement of the front façade of the building and the neighbouring 3 party structure. This was assumed to have been caused by the poorly constructed piles, and fines wash out during the excavation process.
The client had just purchased a property which was suffering from subsidence at the rear of the property. The subsidence cause at the rear elevation was due to the property being built on top of a layer of peat which was the primary cause of the subsidence.
