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. It can only be cured by installing a chemical DPC which we can supply, Koster Crisin.
