Rising damp treatments
Damp walls will damage plaster, wall paper, paints and skirting boards. The core of the damp problem needs to be rectified before cosmetic repairs are undertaken. The most economical way to treat rising damp and the best way to reduce damp proofing costs is with a damp proofing injection cream.
The cream is injected into the affected walls and once it enters the wall it turns into a liquid. The liquid then penetrates the brickwork pores, cures and hardens. This chemical DPC creates a strong, water-repellent barrier, stopping water from rising up the wall.
A less cost effective rising damp treatment is to install a new damp proof course membrane. This involves removing the bricks around the affected area and replacing the DPC with a new physical membrane.
If you have a bridged damp proof course then you will need to remove or fix the issue that is causing the bridge. For example, if the external ground level is too high then you will need to dig a trench at least 6 inches below the current DPC. But make sure to not let the new trench collect water as this may cause further damp issues.
Carrying out quick-fixes, like painting over damaged decor, or re-pointing brickwork will only lead to bigger damp control problems in the future. You will need to continually re-paint and the damp walls will continue to degrade further.
We always recommend seeking the advice of trusted damp control specialists like APP Protect for an honest evaluation of your damp problems.
