House walls creating moisture

[ghosthunter]

Sir GH, anong water proofing chemicals for walls? sa slab kasi ung waterproofing membrane ginagamit namin.

Look for "Concrete Sealer".

Use it like paint but it's a clear liquid and also dries clear. It's function is to seal and block all the pores in concrete to prevent water getting through. Downside, if the wall develops a crack later, water will get through that particular crack.

Waterproof membrane is actually the better solution IF you can still access the entire area that needs to be waterproofed. But it also means an extensive amount of work needed to be done to restore and hide the membrane.
