Wall Dampproofing & Penetrating Damp Treatment in Bloemfontein

Damp coming through exterior walls is either rising (from the ground) or penetrating (from outside through the wall). Each needs a different treatment. We diagnose which type you have, treat the actual cause, and only then restore the wall surface - because painting over active damp always fails.

Frequently Asked Questions

What is the difference between rising damp and penetrating damp?

Rising damp travels upward through masonry from ground moisture and typically shows as a horizontal tide mark on walls. Penetrating damp comes through the wall face or roof and appears as patches at any height, often after or during rain.

Can I just paint over damp walls?

No. Paint applied over active damp fails within months. The moisture pushes it off from behind. The source must be treated first.
