Resolving Cases of Rising Damp for Customers in Richmond

For the long-term prevention of rising damp and moisture decay, get in touch with the experts at CPM Waterproofing Services Ltd. With many years of experience, our team carry out a damp treatment that protects properties in Richmond from timber decay and structural damage, such as rising damp, dry rot and wet rot. A chemical barrier of DPC (damp proof course) is injected into the walls, preventing moisture from passing into interior spaces. If you think your property may already be suffering from rising damp, you may notice one of the following signs:

• Flaky or Bubbling Plaster
• Rotting Window Frames, Floorboards, or Skirting Boards
• Wallpaper That Lifts
• Damp or Wet Patches Appearing on the Walls
• Rusting Steel and Iron Fasteners
• Crumbling Mortar between Bricks or Stonework on the Exterior of the Building
• Stains or Tidemarks on Walls
• Paint Won't Adhere to the Walls

A Two-Part Treatment

The DPC we inject is a concentrated thixotropic silane/siloxane cream that forms a barrier against rising damp. A silane vapour is released as the cream diffuses. This reacts with the silica in the masonry, forming a water-repellent resin. As there is no liquid or pressure involved in the treatment, the walls will dry quickly and be saved from unnecessary stress.

The DPC injection is just the first part of the treatment. The second involves re-plastering the walls with sand and a cement render that incorporates a waterproofing additive. This reduces the migration of salt from the wall to the surface of the plaster. Thanks to this double protection, you can rest assured that you will no longer suffer from a rising damp problem.

Aftercare and Advice

CPM Waterproofing Services Ltd is committed to helping our customers, and we will never leave a job half done. That is why we make you aware that the walls may still contain a considerable amount of residual water after the insertion of the chemical damp proof course. This will need to dry out naturally. Although the general rule is that one inch of water dries out a month, this will differ for each wall.
