Description - Subsidence damage repairs

Overall claim Value - £5.7 million

The building comprised a large purpose-built series of terraced mansion flats formed from eight blocks and five storeys with a total of seventy-one apartments. Extensive damage was caused by tree root related subsidence. The proposed repairs were complex due to underpinning being required alongside previously undertaken underpinning and the design parameters to take into account the significant loadings imposed by the five storey building.
