Damp Proof Course

​

A **Chemical Injection Damp Proof Course (DPC)** is a modern, effective solution for tackling rising damp in buildings. Rising damp occurs when moisture from the ground moves up through the walls of a property via capillary action. This can lead to a range of problems, including damp patches, peeling paint, mold, and even structural damage if left untreated. A chemical injection DPC is designed to create a waterproof barrier in the masonry, stopping the upward movement of moisture.

​

The process involves injecting a specially formulated chemical solution into the masonry of the walls, usually at the base, where the damp is most prevalent. The chemical reacts with the wall’s materials to form a water-repellent barrier. This barrier prevents moisture from rising further up the wall, effectively halting the progression of rising damp.

The chemical injection creates a protective barrier at the point where the original DPC should have been, or where an old DPC has failed. This ensures long-term protection against the negative effects of moisture buildup in the walls.

Drilling

Small holes are drilled into the mortar joints of the affected walls, typically around the ground level where moisture is entering.

Fill

A damp-proofing chemical, usually in liquid or gel form, is injected into the holes under pressure. This ensures that the solution penetrates deep into the masonry to form a continuous barrier.

Grind

The affected mortar courses are ground out to removed the sight of the holes that are drilled.

Repoint

After the injection process, the holes are sealed, and any excess chemical solution is left to cure and form the waterproof barrier.

Why Choose Chemical Injection Damp Proofing?

  • Effective for Rising Damp: It is specifically designed to treat rising damp in buildings with solid walls, where traditional damp proofing methods (like installing a physical DPC) may not be feasible.

  • Minimally Invasive: Unlike some other damp proofing methods, chemical injection requires minimal disruption to the property. There’s no need for extensive excavation or major alterations to the structure of the building.

  • Cost-Effective: Chemical injection is often more affordable compared to alternative damp-proofing techniques, such as installing a new physical DPC.

  • Long-Lasting Results: When applied correctly, a chemical injection DPC can provide lasting protection, often for decades, ensuring your home or building remains dry and safe from moisture damage.

Benefits of Chemical Injection DPC

  • Prevents Structural Damage: By stopping moisture from rising, a chemical DPC prevents rot and decay in wooden beams, floorboards, and other structural elements of your home.

  • Health Benefits: Reducing damp conditions helps to prevent the growth of mold and mildew, which can lead to respiratory problems, allergies, and other health issues.

  • Improved Property Value: Damp can significantly reduce the value of a property. Installing a chemical DPC helps protect your investment and maintain the building's value.

Signs You Need a Chemical Injection Damp Proof Course

Look out for the following signs of rising damp:

  • Damp Patches: Dark, wet patches appearing on walls, especially near the floor.

  • Peeling Paint or Wallpaper: Moisture causes paint and wallpaper to peel or bubble.

  • Musty Odors: A persistent damp or musty smell, which can indicate mold or mildew.

  • Mold Growth: Mold often appears on walls or ceilings as a result of high moisture levels.

  • Decaying Woodwork: Timber elements like skirting boards, window frames, or floorboards may start to rot if moisture is present.

​

A Chemical Injection Damp Proof Course (DPC) is a reliable and effective solution for tackling rising damp in properties. By creating a chemical barrier in the masonry, it stops moisture from seeping up through the walls, preventing further damage to the structure and improving the overall health of the building. Whether you are dealing with an older property or need to replace an old or failing DPC, this method offers a cost-effective, long-lasting solution.

If you're experiencing rising damp, it’s essential to act quickly. Contact a qualified professional to assess the situation and recommend the best treatment for your home or building.
