Damp proofing is the technical process of preventing moisture from entering a building's structure.
At Barrier Property Care, we combine 30 years of experience with advanced diagnostic tools to identify and eliminate the root cause of damp, including rising damp, penetrating damp, and condensation.
Damp is often a hidden issue until it causes visible damage. If you notice any of the following, your property likely requires a specialist survey.
| DAMP TYPE | PRIMARY CAUSE | COMMON SIGNS | THE "BARRIER" CURE |
|---|---|---|---|
| Rising Damp | Capillary action drawing ground water up through porous masonry due to a failed or missing DPC. | Tide marks (usually up to 1m high), salt-damaged plaster, rotting skirting boards, and peeling wallpaper. | We install a new Chemical Damp Proof Course (DPC) and replace contaminated plaster with specialist salt-retardant rendering. |
| Penetrating Damp | Water "soaking" through the external envelope of the building, often due to structural defects. | Isolated damp patches that worsen after rain, blown external render, crumbling mortar, or water-stained ceilings. | We identify external faults like blocked gutters or cracked bricks and apply Silane-based water repellents to the external masonry. |
| Condensation | Warm, moist air hitting cold surfaces (like walls or windows), common in modern living with poor airflow. | Black spot mould in corners or behind furniture, "streaming" windows, and a persistent musty smell. | We install Positive Input Ventilation (PIV) systems and specialized extractor fans to permanently regulate humidity and airflow. |
| Lateral Damp | Occurs when the external ground level is higher than the internal floor, allowing water to bridge into the wall. | Dampness on the lower part of walls, specifically in basements, cellars, or properties built on a slope. | We utilize Structural Waterproofing (Tanking) and "dry-lining" membranes to create a physical barrier between the earth and your home. |
