All was going well whilst doing the ground works for the upgrade to the members car park until we found that one area of the car park had become locked up and water was not draining away. The mixed material of old hardcore and whin dust mixed with some sandy loam had completed sealed up making water movement through it impossible. We decided to dig a holding sump and back fill it with some larger hardcore then some new/clean hardcore and dust, that should solve that problem,hopefully??
