I recently moved into a house with a garage at the bottom of the garden which has a damp proof membrane (DPM) that protrudes out at the base of every wall by approx 4 to 5 inches.
Can I safely trim this off without affecting the damp proofing?
I want to fit some interlocking garage floor tiles to make the space less dusty and cleaner but currently can't do this as the DPM will stop me getting the tiles tight to the walls.
Around the single door frame and garage roller door entrance the DPM is already trimmed down to be flush with the ground, so I believe I should be able to trim this off but this is my first time ever having to look into doing this so I want to be sure.
