My mother has an insurance claim with FBD for subsidence/settlement. The house was built in the mid 1960's and was fine until last summer when we noticed large cracks appearing inside and outside the house. We have had soil tests carried out and they show that the house is built on filled ground. Our engineer and loss assessor now think it is settlement as opposed to subsidence and have recommended underpinning the gable end of the house and knocking the garage beside the house. Our preference was to have the foundations stabilized with a geopolymer resin by Geobear but the engineer and soil investigation company have recommended against this. The drains also have to be repaired but they are not the main cause of the movement in the house. Costs are now getting more and more. Does anybody have any recommendations or have they ever had their house underpinned and if so how invasive was it?
Many thanks in advance!
