Cement Waterproofing
Hey All! Trying to come up with a good way to waterproof between two cement areas. One area is a walk way, and the other is the basement foundation. I'm focusing on increasing the drainage and water flow through this particular area to try and divert it away from the basement.

I'm thinking some self adhesive flashing to form a right angle between the foundation wall and the walk way, but maybe there's a better way out there? Anyone have any ideas? Pics are attached.

I used PL polyurethane sealant (70+ tubes!!) to replace all of the creepy spacer board from the garage slab all around the cement seams along the side of the house, as well as in the sloppy gaps between the house slab and the block walls inside. going on 4 years and no leakage. I also used it under the bottom plates for the stud walls when I gutted and rebuilt the basement. at $5.47 a tube, it's not cheap. but there has been no pullaway.

you also need to check and see if there is any pathways water has cut under the walks headed to the house. I had lots. shot low-expansion foam under there. the old stiff pro at the paint desk steered me right impho.

we'll see what the 10 and 20 year marks bring...

sig: if this is a new economy, how come they still want my old-fashioned money?

Cement waterproofing is very good for those that want to use it on the cement surfaces of their home, but want to maintain the certain color scheme they have chosen.
