Hi all, havent been around for ages for all the usual reasons, yawn.
Anyway my Mother in law has bought a bungalow and wants the paving done. They want a level garden and have ramp and level access at the front door. At the rear a small extenstion will be built with a stepped tray dpc etc to allow for level access through sliding doors.
However she wants to raise the whole level around the rear of the house to remove the gradual 8'' slope and also get the garden falling away from the building as the settlement has caused the original 3x2 path to drop maybe 3'' and water which used to fall onto the lawn pools along the path in many areas. The dpc clearance is fine the only issue is the sub floor vents.
The house is however not timber floor but concrete block and beam/ possibly precast slabs and i assume this is because of poor ground and it was probably piled (piling of houses across the road being built currently)
So my query is because the sub floor needs vented but not as well as a timber subfloor could i create a small 4-6''trench all along the back wall to keep the subfloor vents clear and cover it with a grill?
A bit like a tiny lightwell to a basement. Anyone ever done this approach? Comments of wise up, stupid idea etc welcome.
