Rising damp is when water from the ground enters the structure by capillary action making its way up the walls and stops at about 3ft (approx. 1m). This is usually controlled by using a physical barrier or damp proof course (DPC) at a minimum of 150mm above ground level; this takes into consideration rain splashing onto the wall above DPC level and also elevated ground levels. If there is no DPC in place, if it has been damaged or has deteriorated then it is possible to install a remedial DPC to control the rising damp. This can be done by installing a chemical DPC which is strategically injected into the masonry.
Once the DPC has been installed the walls will need to dry out. The rate at which the wall will dry is 1 inch per month per thickness of wall, if well ventilated and unrestricted both sides of the wall. So for example a 9 inch thick wall will take 9 months to dry out. Because of this drying out time the damp/water vapour will affect any finishes i.e. plaster, paint. To prevent this from happening you can use our PT slimline or PT Lath membrane. When fixed to the wall it creates a cavity that allows the wall to dry out and breathe. This is then re-plastered and blended into the existing plaster and once dry can be re-decorated as normal.
