What is DPC Injection?

DPC (Damp Proof Course) Injection is a targeted treatment to stop rising damp by creating a water-resistant barrier within the wall structure.

This process involves injecting a specialist chemical solution into drilled holes along the base of affected walls. The solution cures to form a damp-proof layer that stops moisture travelling upwards from the ground. It is highly effective for properties with failed or missing damp-proof courses.

DPC injection is ideal for older homes and provides reliable long-term protection with minimal disruption. It’s a cost-effective solution to preserve your property and prevent damp-related damage and health risks.

Protection of Property Value

Why is DPC Injection Important?

Rising damp can cause significant structural damage and ongoing health concerns if not properly treated.

As moisture travels through porous brickwork, it can damage plaster, create mould, and compromise your property’s foundations. DPC injection is a proven method to stop this process by installing a modern damp barrier without major disruption.

It’s especially vital for properties where the original damp-proof course has failed or was never installed. Our DPC solutions help avoid costly repairs and ensure your home remains healthy and protected for years to come.

Frequently Asked Questions
Learn how Damp Proof Course Injection (DPC) safeguards your property, prevents costly damage, and ensures long-term protection
How long does a DPC injection last?

When professionally applied, a DPC injection can last for decades, often up to 20–30 years. Regular maintenance checks are recommended to ensure its effectiveness over time.

How long does the DPC injection process take?

The time required for DPC injection depends on the size of the property and the extent of the damp problem. However, most DPC injection treatments can be completed within one to two days.

Will damp proof course injection fix my damp problem permanently?

Damp proof course injection is highly effective in preventing rising damp. However, if the damp is caused by other factors like poor drainage or condensation, additional measures may be required. It’s important to identify the root cause of damp to ensure the right treatment is applied.

How do I know if I need a DPC injection?

Common signs of rising damp include damp patches on walls, peeling paint or wallpaper, mould or mildew, a musty smell and crumbling plaster near the base of walls. If you notice any of these issues, it’s worth having a professional assess your property for damp.
