Is this to stop water coming up through the floor? If so I've got the same problem in my garage, what have you put down?
See the dark patch across the bottom at the back? My water is coming through the bottom course of bricks and between the floor and the walls.
I've painted a coat of this stuff on it - http://www.screwfix.com/p/sika-5-28kg/83502
Needs a second and maybe third coat though - only problem is, it won't dry out - because of the wet bricks being against the soil out the back.
Hopefully it will dry eventually. Since its pissing it down now, I'm going to nip round after work and see if its a swimming pool or not again.
