So I dug out the little trench next to my external wall (cos the driveway was laid too high - up to the air bricks...) and still have some rising damp inside.
Anyone got experience excavating the crap out of their cavity walls (there's no insulation... But I suspect a lot of debris/run-off). Any tips?
what is the ground flooring substructure? my only experience is from doing some prep for new floor boarding to be layed, taking up the old ones up only to find a load of damp soil..
