Does DIY Damp Proofing Work?
We at John Newton & Company are often asked whether damp proofing can be done as a DIY damp proofing job. There is a wealth of information available and multiple diy damp proofing products are available online which promise and easy fix.
However, unless you are a damp expert diy damp proofing products can cause a minefield of problems. Where DIY damp proofing can seem like a low cost solution, it can result in a far more expensive strategy than planned, and often the damp problems can return. We are often contacted when a DIY damp proofing job goes wrong, with problems like the following:
- “I used DIY damp proofing cream in my damp basement but the water keeps coming in”
DIY damp proofing is never advisable in cellars or basements. Damp proofing below ground spaces needs the advice of a specialist basement waterproofing contractor, as the job is not just about damp proofing walls, it is about ensuring that a waterproofing system is in place which will divert the water out of the property.

Damp Proof Membranes – An Introduction

Detail, Newton 503 Mesh fixed with Newlath Plugs
A damp internal surface can occur from moisture rising from below ground level through old porous brickwork. This may be due to the original damp proof course being damaged, breaking down through age, or displacement due to slight movement of the property over years. Also in my older buildings, the external ground level has over the years risen to above the original slate or felt damp course. Rising and penetrating dampness cause a number of detrimental affects to internal finishes such as staining and discolouration, peeling paintwork/finishes, blown plaster, salt and oil contamination etc. Damp proof membrane solutions would be the recommended solution to these problems.

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.
