DPC, or Damp Proof Course, installation involves injecting a damp-proofing solution into a wall to prevent rising damp. This is typically done by a specialist.
The DPC Injection Process
The process involves several key steps:
-
Drilling Holes: A technician drills holes in the affected wall, spaced approximately 100-120mm apart. These holes are positioned at least 150mm above ground level. This spacing ensures adequate coverage of the wall with the damp-proofing solution.
-
Injection: A damp-proofing liquid or cream is injected into the drilled holes. This solution is designed to be absorbed into the wall's structure.
-
Barrier Creation: The injected solution creates a horizontal barrier within the wall, preventing further moisture from rising. This newly created barrier effectively stops the capillary action that draws dampness upward.
Important Considerations:
- Professional Installation: DPC injection is best performed by experienced professionals who understand the nuances of damp-proofing techniques and the specific characteristics of different wall types.
- Material Selection: The choice of damp-proofing solution depends on the wall's material and the severity of the damp problem. A professional will assess this and select the appropriate product.
This method offers a non-invasive way to address rising damp problems, significantly improving the condition of the affected wall.
