Any quick/easy cure for rising damp caused by flock infill of cavity bridging the DPC?
Proprietary cavity wall insulation materials per se will not cause moisture to cross the cavity and so bridge a dpc. So if the insulation has been installed as a ‘retro-fill’, there should not be a problem on this count provided the cavity is clean and free of mortar droppings. Occasionally isolated damp patches can be caused in new construction if excess bricklaying mortar falls on the ties retaining the insulation panels in the cavity. If it really proves to be a case of rising damp, then a remedial damp proof course installation will solve the problem. So an inspection by a trained and qualified surveyor is recommended.
