Is A Damp Proof Course Necessary With Damp Proof Membranes?
Not necessarily. Damp proof course failure is a leading cause of damp problems in properties. Indeed many older properties there was no damp proof course installed so once you have established this then you will know whether you need to install a physical damp proof course, a chemical injection or a dimpled sheet membrane as a choice. DIY damp proofing websites show you all these products above but which one do you chose in which circumstance? Some products just don’t work in certain builds. For instance I have witnessed properties with cavity wall insulation damp and builders installing a cream into the cavity wondering why it wasn’t working! The simplest damp proof membrane application for damp proofing walls is in my opinion a dimpled damp proof membrane. These damp proof membrane products negate the need for a damp injection, are less likely to result in problems like other diy damp attempts (black jack, waterproofing paint) even poor quality damp proofing jobs.
