Everytime it rains I get a flood in my garage. It's caused by the garage 2 up from mine which has got holes in the roof, so everytime it rains it runs through the floor of the next one, and then into mine.
Is there any stuff, such as paint on tar etc... I can use, to seal the brickwork? Bearin in mind that it's always gonna be wet, I can only dry it out so much with a mop and bucket.
