This piece of wall was hollow when I tapped it. It is very near to drain which had a silly waste wipe that was far too high and pointing at the wall! I have fixed that with solvent weld and it now points downwards just above grate level
Are the engineering bricks the DPC? (they were very damp)
I am slightly concerned about the concrete ground level which butts the house, do I need to be ?
TIA
