cannot do that as the back of the garage has concrete steps upto the garden. a dpc membrane was put against the wall and water sealer used before the steps were built. but it doesnt seem to have made any difference to the moisture coming through.
im New here and need a bit of help.
i have an internal garage wall (solid breeze block) that has a lot of damp coming through it. i have used damp paint on it in the past, and then last year i put kingspan board onto it to hide the damp and green mould on it.
but i am thinking of taking it off...
