How Damp Proofing Is Done

Damp proofing a wall typically involves removing affected plaster, injecting a silicone-based damp-proof cream into the mortar joint, and applying a waterproof protective layer. In most cases, holes are drilled at regular 12 cm intervals before the cream is injected to create a new damp-proof course. The treated area is then sealed, replastered, and finished […]

Treating damp walls starts with identifying the source of moisture. Common causes include rising damp, penetrating damp, or condensation. The correct treatment depends on the cause. 1. Fix the Source of Damp (Critical First Step) Before any internal work, the moisture source must be resolved. This may include: ⚠️ Treating internal walls without fixing the […]

What is Damp Proof Injection?

Damp proof injection is a fast-acting, long-term solution designed to treat rising damp in buildings. This process involves installing a chemical damp proof course (DPC) using a water-based silicone fluid—commonly known as damp proof cream. By forming a protective barrier within the walls, this method effectively prevents moisture from rising through the masonry, thereby protecting […]
