Our Damp Proof Course Solutions:
Damp proof course in Dorset & Hampshire
If you’ve noticed peeling paint, crumbling plaster or damp patches rising from the ground, your home may be suffering from rising damp. This issue can weaken your property’s structure, cause mould growth and affect indoor air quality. At Bournemouth-based Proofterior, we specialise in damp proof course (DPC) installation and repair in Dorset and Hampshire, ensuring homes stay dry, protected and structurally sound.

What is a damp proof course?
A damp proof course (DPC) is a protective barrier within a building’s walls designed to prevent rising damp from moving upwards through the brickwork. Most modern properties are constructed with a built-in DPC, but over time, this protective layer can weaken or fail due to various factors. In older buildings, natural wear and tear can cause deterioration, while external materials such as soil, paving or render can bridge the DPC, allowing moisture to bypass it. Some period properties may lack a DPC altogether or suffer from poor initial installation, making them more vulnerable to damp issues.
If a compromised or missing DPC is left untreated, moisture can spread throughout the property, leading to damage to walls, floors and interior décor. Addressing the issue promptly is crucial to maintaining a dry, structurally sound and healthy living environment.

How does damp proof course injection work?
At Proofterior, we use damp proof course injection technology to create a new moisture-resistant barrier inside your walls. This is an efficient, cost-effective and minimally invasive method to stop rising damp. The process involves:
- A thorough property assessment by our expert surveyors to diagnose the extent of the damp issue.
- Drilling small holes at precise intervals along the affected walls.
- Injecting a high-performance damp-proofing solution into the walls, forming a water-repellent barrier.
- Allowing the walls to dry naturally before carrying out any necessary replastering or decorative repairs.
This method eliminates rising damp at its source, protecting your home from further damage while preserving its structure.
