Exterior Foundation Water Protection?


Hi everyone, I'm running a larger pipe/down spout repair job on an old house with a granite stone foundation. The pipe repair work is straight forward and when I've done it in the past we would just cover them back up, pour slabs and be on our way. This time though I thought it might be worthwhile to check out exterior foundation sealant products while everything is exposed for some extra protection.

Given the type of foundation it is what would be a recommended product? Do the rocks have to be power washed in order for the sealant to bond to them? Would applying it make much of a difference in that it's not cinder block? Thanks for reading.

Actually, let me rephrase- is there a heavier duty, tar-based product that will adhere to dirty surfaces? Power washing is not an option.

No the surface must be clean and dry from any foreign objects

Stiff broom and wire brushes perhaps to clean it?

Compressed air can work almost as well as water. Wire brush then air. But it takes A LOT of air

I have never power washed because it creates such a mess in the bottom and takes forever to dry.

We use wire brushes attached to recip saws, then like Dom-mas said, hit it with air and works perfect. Not a clean job for the guys in the hole but better than running a dry grinder!

Or use a larger wire cup brush on a grinder too

I think some sort of rubber that you can roll out and place over the wall would be better then trying to get some gobbly gook to stick.

If the surface has dirt on it, nothing will adhere to it. Once you get it clean, you have some options.

You could use platon also, or any other dimpled membrane

I'M 100 % with dom on that. I have been using Platon since 2005 and have been thoroughly pleased with the results.
