What is rising damp?

Rising damp is caused by moisture containing natural formed salts rising from the ground through a capillary like action. Salts and minerals in the ground are normally harmless. However, when combined with water these salts dissolve and become acidic substances.

Rising Damp is usually evident in the form of stained walls, blistering and peeling paintwork and salt accumulation of up to 1 metre high. Rising damp, if left untreated, can cause serious damage to a building's structural integrity, not to mention damage to timber work i.e. flooring, architraves and skirting boards. As a health issue, Rising Damp can be detrimental to people suffering from asthma or any other breathing disorders.

Detecting rising damp

A qualified DampShield Technician will carry out a thorough inspection using a digital moisture detector. Our Technician will determine by the metre reading if the dampness is caused from rising or penetrating/lateral damp. A detailed quote will then be forwarded to the owner outlining the recommended work/s to be carried out including the specifications and costs involved to rectify the damp problem.

How to fix a damp problem

The permanent solution to remedy your Rising Damp is to install a Traditional Polypropylene Damp Proof course. The Polypropylene is a 2mm thick sheet which is hard and solid, yet flexible. It is resistant to acidic salts and minerals and cannot be torn or ripped during its installation.

Our Damp Proof Course creates a continuous barrier against Rising Damp. Other damp proof courses made from lead, slate, zinc, tar and bitumen, can be attacked by rising damp.
