My garage wall has a grass bank next to it. In heavy rain the garage gets very damp around the base of this wall and also from a patch in the centre of the floor.
I've dug a small channel into the grass bank next to the wall to try and alleviate this however at one end the bottom of the channel is pretty much level with the damp course.
Is there any cheapish DIY way I can tank the floor and lower part of said wall to stop it getting so mouldy in there? I'm thinking along the lines of some sort of paint on product.
