I’ve had my garage re-roofed but still a problem with damp penetrating the floor.
It’s a large single skin brick built garage with 18mm ply decking and EPDM roof. So the garage is definitely as dry as it will get (post re-roof) but there is still damp patches emerging through the slabs and where the side walls meets the floor.
I’d like to use it as a bit of a utility space so am prepared to put some work into removing as much damp as possible.
It is a slab base and knowing the bloke I bought the house from, almost certainly has no DPM underneath, same with the walls.
One problem is I’ve no access to the sides of the garage as it runs form garden to garden (soil on both sides) So I can’t really do anything in terms of adding any drainage or DPC on the outside.
So, what to do….
I’ve had a few ideas…tank the floor, then put some sort of poly sheet over this and then lay rubber tiles on top…
But I’m not sure what to do about the walls. Take the walls, run some sort of DPM across the floor and up the walls? ID rather not batten the walls in any way as space is at a premium.
To add a little added complexity, the floor is also sloped and could do with levelling. So not sure to do about that either in terms of DPM first, levelling compound after?
Many thanks in advance for any help as its making my brain bleed
