Penetrating & Lateral Damp
Permanent solutions for penetrating and lateral damp — designed to control moisture ingress at source and protect internal finishes long-term.
Why Penetrating/Lateral Damp Is A Problem
Penetrating and lateral damp are caused by external moisture pressure forcing water through walls, joints, and defects — often leading to progressive internal damage if not correctly managed.
Recurring Repairs
Structural & Material Deterioration
Salt Contamination & Finish Failure
Mould Growth & Poor Indoor Air Quality
How We Fix It - Properly
Penetrating and lateral damp requires a system-based internal approach, not surface coatings or cosmetic repairs.
1. Assessment & Ingress Identification
We carry out a detailed inspection to determine how and where moisture is entering the structure. Particular attention is given to floor-to-wall junctions, construction joints, cracks, and service penetrations.
2. Strip Back to a Sound Substrate
All failed plaster, paint, salts, and contaminated finishes are removed to expose a clean, stable substrate. Correct preparation is essential for the performance of any internal waterproofing system.
3. Seal Ingress Points & Junctions
Identified ingress points such as cracks, penetrations, and junctions are repaired and sealed using compatible repair mortars and flexible sealing methods where required. This step controls active moisture paths before tanking is applied.
4. Internal Tanking & Waterproof Plaster System
A cementitious negative pressure tanking system is applied to affected walls (and floors where required) to form a continuous internal barrier against lateral moisture ingress. The system is reinstated with a waterproof plaster build-up, ready for final finishes.
