Rising damp is when moisture from the ground travels up the walls of a building through capillary action. When this happens, you are likely to see signs of rising damp on internal walls like staining and salt deposits. The excess moisture in the wall can cause internal damage to plaster, paint and wallpaper as well as external damage.
Treating Rising Damp
The best way to treat rising damp is by installing a new damp proof course (DPC) through chemical injection. A chemical damp proof injection forms a new DPC that prevents water from rising up from the ground. You inject a specially-formulated chemical into either the brick or mortar joint depending on the product selected. When the chemical injection cures, it creates a water repellent barrier that prevents damp from rising up the wall.
Permagard manufacture and stock several types of rising damp treatment. These include damp proof injection chemicals, ranging from water-based concentrates to ready to use damp proofing creams.
- Kiesol C is the highest strength damp proofing cream on the market providing a permanent horizontal barrier against rising damp. It is approved for use in highly saturated walls and has passed rigorous European testing. It is available in cartridges or 5 litre tubs. Once inserted into the mortar course, the cream slowly reverts to a liquid. This allows it to penetrate deeply into the masonry and be completely absorbed. We also sell a complete DPC injection kit featuring Kiesol C.
- Aida Damp Proof Injection Cream is a highly effective treatment for rising damp. It is easy to install either directly from the cartridge or from a low pressure injection unit into the mortar joint. We also stock complete rising damp solution kits that include everything you need for highly effective chemical injection.
Re-Plastering after a new DPC
Once you have treated the rising damp, it is essential that you re-plaster internally following the correct specification. By using the right spec, you prevent further issues with salt contamination. Permagard stock all the required products (available on this page) for re-plastering - these include Salt Neutraliser to treat any salt contamination before the re-plastering takes place and Permagard Waterproofer for re-rendering. We now offer also offer damp proof membrane kits to speed up the re-plastering process and isolate new finishes from damp, salt contaminated walls.
You can also protect a property from rising damp with a polythene damp proof course. These are best installed during new construction. At Permagard, we stock extremely durable DPC membranes manufactured by Capital Valley Plastics.
