How Do I Deal With Penetrating Damp?

Penetrating damp creates damp walls and can cause a number of detrimental affects to internal finishes. It is always imperative to diagnose the cause of the dampness, for instance in a damp cellar it will usually be because the external ground levels are higher which means that earth bearing against the structure makes the wall damp. Above the ground buildings in exposed locations or that have porous building substrate can suffer from moisture penetration.

Rising and penetrating dampness causes staining and discolouration
Newton Damp Proofing Systems are a range of High Density Polyethylene and Polypropylene membranes which are moulded into a stud formation. The membranes prevent any moisture and moisture vapour and associated salts and contaminants within the structure affecting the internal finishes by providing a physical barrier between the old surface and the new finish. Whether installed by a specialist or if you opt for DIY damp proofing this will significantly prolong the longevity of the internal finishes whilst the damp proof membrane still allows for natural evaporation of moisture from the damp walls and unhindered movement of air to take place in the gap provided by the studs of the membranes.
