Hi wondered if anyone could give some ideas.
Bought a 1960s bungalow, its built on a downward slope, and its had a couple of rooms added at garden level, I understand around 25 years ago, so you walk down to these 2 rooms and the garden.
One of the 2 downstairs rooms just feels a bit damp / musty. Previous owner has left receipts of work done for dampness i.e painting bitumen paint, adding air brick, refurbing the musty room.
It's evident that the big part of the problem is the garden ground level which is at the dpc of the downstairs rooms, and the side wall where neighbour has their garden / hedges (we own a small strip down the side, its 40cm over dpc (neighbours garden is higher)
I've dug a trench down that side below dpc and was going to put some concrete slabs against the neighbours soil / higher ground level, put weed membrane and backfill with large gravel for drainage. However I have read that this will eventually fail? as the gaps get clogged with soil.
Any ideas? theres a lot of clay in the soil I've noticed, Im thinking I need a soak away
