Damp proofing a garage

8 Sep 2008

We wanted to use our garage for storage and also as a workshop, but things stored inside do tend to get a bit damp. We have tanked the walls - up to 1m round the sides and up to the top at the back, but this hasn't made a big improvement.

Can anyone suggest how to do a better job of it?

Bit of info: There is a crack all the way along the concrete floor from front to back. It is one of a row of 6 garages - situated one from the end. There is no soil above the floor level on any sides. There is no visible water or damp on the walls.

Any help much appreciated!
