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.
The permanent solution to rectify 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 easily attacked by rising damp.
Signs Of Rising Damp
Installing A Physical Damp Proof Course
STEP 1
The surrounding area is covered up with drop sheets protecting the floor and furniture. A horizontal cut is made through the mortar in the first practical course of brickwork above floor level. This process is carried out one metre at a time. Cavity walls are cleaned of rubble and debris to prevent bridging of the damp proof course
STEP 2
The DPC is inserted and overlapped to provide a continuous barrier. Aluminium wedges are inserted between the DPC and the above brick course for extra support. A vertical membrane (heavy duty forticon plastic) is inserted at the DPC level down to between the floor and wall to protect floor boards and skirtings from dry rot.
STEP 3
The brickwork is then re-mortared. The DPC installation will prevent rising damp from reoccurring in the future. However, if the existing wall surface is rendered or plastered, it is advised to strip the wall up to 1 metre in height to expose the brickwork. This procedure will be carried out at the time of DPC installation.
