Service Overview

Professional Damp Proofing
Services in Sri Lanka

Do you have damp patches, peeling paint, or musty odors in your home? We offer expert damp proofing solutions in Sri Lanka to protect your walls and floors from moisture damage, mold and structural decay.

Dampness is deceptive — it often remains hidden behind walls and finishes for months before becoming visible. By the time you see a damp patch, water has already penetrated deeply into the wall structure, causing damage to the substrate, insulation and interior finishes. Left untreated, damp conditions lead to mold growth, which poses serious health risks to occupants.

Our damp proofing solutions target the root cause of moisture ingress — not just the symptoms. We use crystalline and cementitious barrier systems that penetrate deep into masonry and concrete, creating a permanent waterproof barrier that cannot be stripped away by subsequent water pressure.

Signs You Need Damp Proofing

Is Your Building
Affected by Damp?

Damp or wet patches on interior walls — especially at lower levels
Peeling, bubbling or discoloured paint or plaster
Musty, earthy odors inside rooms
Visible mold or mildew growth on walls or ceilings
White salt deposits (efflorescence) on walls
Rust stains tracking down from wall ties or rebar
Condensation inside the building even in dry weather
Wet or damp flooring — especially in ground floor rooms

Types of Damp

Damp Problems We Solve

⬆️

Rising Damp

Ground water wicking upward through walls via capillary action. Common in older buildings without a damp-proof course.

🌧️

Penetrating Damp

Rain or surface water penetrating through external walls, particularly where render or pointing has failed.

🏗️

Basement Moisture

Hydrostatic groundwater pressure pushing moisture through basement walls and floors.

🚰

Lateral Damp

Water passing horizontally through walls from soil contact — common in retaining walls and below-ground structures.

💦

Condensation Damp

Internal moisture condensing on cold surfaces, often linked to inadequate ventilation or insulation.

🔧

Structural Damp

Water ingress through cracks, construction joints and structural movement — requiring combined crack injection and damp proofing.

Our Solutions

Damp Proofing Methods
We Use

Crystalline Waterproofing (Duraseal XP)

Applied to concrete and masonry surfaces, Duraseal XP penetrates deeply and chemically reacts with water to form insoluble crystals that permanently block capillary pathways. Self-healing — crystals re-activate when the structure is re-wetted.

Cementitious Barrier Coating

Rigid or flexible cementitious systems applied as a tanking coat to internal wall faces — ideal for basements, retaining walls and below-ground structures where excavation is not possible.

Render & Coating Systems (DuraCoat Deco)

Water-repellent render applied to external walls — stops lateral and penetrating damp while providing a protective and decorative finish to the facade.

Injection Damp Proofing

Chemical injection into mortar courses to create a horizontal damp proof course — specifically for rising damp in older masonry walls where a physical DPC is absent.

Common Questions

Damp Proofing FAQs

Can damp proofing be applied from inside the building?▼

Yes — this is called negative-side waterproofing. Our cementitious tanking systems and crystalline treatments can be applied to internal wall faces, which is often the only practical option in basements or where external excavation is not possible.

How long before damp proofing is effective?▼

Cementitious systems typically achieve full strength within 7–28 days of curing. Crystalline systems continue to develop over months as crystals grow deeper into the substrate. You should notice a significant reduction in moisture within 2–4 weeks of application.

Do I need to redecorate after damp proofing?▼

In most cases, yes — once the damp proofing is complete and fully cured, we recommend waiting at least 28 days before applying new plaster or paint finishes. This ensures all residual moisture has dried out and the new coating adheres properly.
