Can I Use Damp Proof Membranes On My
Damp Cellar?

Newton Specialist Basement Contractors - the most important step towards a dry basement
In a word, no. Damp proofing membrane systems are designed to deal with capillary held moisture only – with smaller damp proofing problems, for example damp walls – and as such are only suitable for above ground application. Where external ground levels are higher than the internal floor levels such as in a damp cellar then there is a risk of hydrostatic water pressure and damp proofing walls only will be a futile exercise if a running water situation occurs Whenever there is a situation where earth is bearing against the structure and making the wall damp a damp proofing membrane solution should not be considered. It would also not conform to BS8102 (British Standard for The Protection of Structures From Water From The Ground).
A Full Waterproofing Membrane System Is Best
The remedial method adopted should be a waterproofing system design and application. John Newton and Company’s website for full details about their Waterproofing Membrane System. Their Newton System 500 is regarded as the premium drained cavity waterproofing system available and the preferred choice for professional specifiers and professional waterproofing contractors alike.

The damp injection method is a common way of dealing with damp problems, but it is not necessarily the best approach. Damp proofing membranes are an alternative for the damp injection method for use on damp walls. They act as a permanent remedial solution for problems such as penetrating damp and rising damp whether it be above the ground or in a damp cellar. Staining and discolouration, peeling paintwork/finishes, blown plaster, salt and oil contamination etc are signs of damp walls and when untreated will continue to make the wall damp. Newton Damp Proofing Membranes have been used for many years as an alternative to the damp injection method, to permanently treat such problems.
When it comes to damp treatment membrane systems, the Damp Proofing Membrane Systems provided by John Newton and Co. are considered to be an effective alternative to most conventional damp proofing methods such as a chemical damp course (DPC), damp injection, cementitious and bitumous paint on coatings and external water repellents. This is because membrane systems generally require minimal preparation and are quick to install. An added advantage is that they are also reversible and can be ventilated. [Read more]

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.
