Damp Proofing
Damp proofing tackles moisture problems in walls — distinct from waterproofing which addresses horizontal surfaces. Rising damp wicks up from below the damp-proof course; penetrating damp comes through from outside; lateral damp passes between split levels. Each needs different treatment. Our specialists diagnose the exact pattern, inject a chemical damp-proof course where needed, neutralise built-up salts, and re-render with breathable plaster systems.

How can I tell if I have rising damp?
Rising damp typically shows as a horizontal tide-mark up to about 1m on internal walls, paint blistering, salt crystals on the surface, and a musty smell. The diagnostic gold standard is a moisture-meter survey plus a plaster salt analysis — included free in our inspection.
Is damp proofing the same as waterproofing?
No. Waterproofing keeps water out of horizontal surfaces (roofs, balconies, basements). Damp proofing prevents moisture rising up through walls or penetrating from outside. Many older Durbanville homes need both.
