Damptec worked at a property in Sheffield to treat the ground floor walls for rising damp and penetrating damp. We used Drybase Flex Membrane because of its versatility. It is a felt membrane system and is much thinner than other membranes. This is particularly useful where the depth of the original plaster is thin. It can be installed directly onto damp substrates and does not require plugs. We applied plaster directly on to it so there was no need to dry line with plasterboard.
