Damp garage

Ectophile

My house has a garage in the back garden - it looks like a DIY build by a previous owner.

The trouble is that the garage has incorporated an existing retaining wall that runs across the garden. On two sides, the ground level is about 5 feet above the garage floor level.

Whenever it rains hard, the rainwater seeps through this wall and across the garage floor. As a result, everything metal in the garage goes rusty, and everything else goes moldy

I'm trying to think of the most practical solution to this problem. One would be to just flatten it, and buy a garden shed to sit on what was the garage floor. Another would be to look at some form of tanking, of the sort used in damp basements.

Does anyone have any bright ideas? Thanks.

I have had some good results using Thompson's water seal . Liberally applied it stopped water penetrating my garden store. Possibly worth trying ( £20 ish ) before anything more drastic.

Thanks, I think that may work.

I will have to work out how to strip the existing paintwork enough for the WaterSeal to penetrate.
