What is Rising Dampness?

Rising dampness occurs when ground moisture seeps up through the walls of a building, causing damp patches and damage to the structure. It’s commonly found in older homes without proper damp-proofing measures in place.

  • Damp-proof membrane sheets
  • Injectable damp-proof course (DPC) cream
  • Masonry drill
  • Damp-proofing injection nozzle
  • Brick pointing trowel
  • Protective gloves and goggles

Step-by-Step Guide to Eliminate Rising Dampness

1. Identify the affected areas: Look for signs of rising dampness such as discolored patches, peeling paint, or wallpaper, and damp musty smells.

2. Prepare the area: Clear the affected walls of any furniture, coverings, or decorations. Remove any loose paint or plaster using a scraper or wire brush.

3. Drill injection holes: Using a masonry drill, create evenly spaced holes along the affected wall at a downward angle. These holes should be at least 10-12mm in diameter and positioned above the skirting board level.

4. Insert the DPC cream: Load the damp-proofing injection nozzle with the required amount of DPC cream and insert it into the first hole. Squeeze the trigger gently, allowing the cream to fill the hole and penetrate the wall. Repeat this process for each hole, working from bottom to top.

5. Seal the injection holes: Once the cream has been injected, use a brick pointing trowel to point the holes with mortar or suitable filler. Smooth the surface for a neat finish.

6. Apply the damp-proof membrane: Cut damp-proof membrane sheets to size and attach them to the affected walls using a suitable adhesive or wall plugs. Ensure the entire affected area is covered for maximum protection.

7. Monitor and maintain: Regularly check the walls for any signs of rising dampness. If necessary, repeat the DPC cream injection process or seek professional assistance.

By following this DIY guide, you can successfully eliminate rising dampness in your home with just a few simple steps. Remember to wear protective gear and exercise caution throughout the process. If you’re unsure or the problem persists, it’s best to consult a professional damp-proofing specialist. Enjoy a dry and healthy living environment!
