Stoke-on-Trent sits on the North Staffordshire coalfield, and historic mine workings are the defining ground consideration across much of the city. Shallow workings, recorded and unrecorded shafts, and ground affected by past subsidence all occur, and their presence changes foundation design fundamentally.
A coal mining risk assessment is the sensible first step on any site where workings may be present. Where they are confirmed, the structural response ranges from reinforced foundations designed to span local voids through to grouting and stabilisation before anything is built.
