For any kind of problem-related to rising damp, United Trade for the perfect revamp.


You must have noticed dampness in the lower area of the wall above the skirting. It might be 1-1.5 meters from the floor or in some cases more than that. You might be wondering that there is no source of water near or behind the damp wall but still there is dampness and plaster start eroding over time. The reason for this kind of dampness issue is rising dampness.

The rising dampness problem is due to not having an effective damp proof course (DPC) or having a faulty damp proof course. DPC is installed as a waterproof layer in the wall to protect the wall from the groundwater. Ideally, it is layered about 6 inches from the outside ground on the external as well as the internal wall. At times DPC is working fine but still, you may witness rising dampness problems.

Reasons could be; something attached to the wall that is passing water to enter your wall above DPC level, the area next to the external wall is higher than your DPC level, or there may have debris and waste building materials which is above DPC level and allowing water to travel in the walls. The reason for the damp problem can be other than rising damp such as broken pipe, leakage from the neighbor house, etc.

There are various ways to treat rising damp problems depending on the severity of DPC failures.

  • Water repellent Chemicals – If DPC is severely damaged, water repellent chemicals are injected at the DPC level. A high-grade chemical is poured into the concrete to stop the movement of water.
  • Applying Waterproofing coating – This is one of the widely used treatments since it is economic, easy to apply, and also can protect the wall against water which is due to other sources.

With over 25 years of experience in the installation of damp proof courses, and having eradicated rising damp problems throughout Australia, you can trust United Trade to fix your damp problem permanently.
