New Treating Damp Guide
John Newton & Company have created the ultimate Guide To Diagnosing And Treating Damp Permanently, yours free when you sign up. This guide is full of information about how to diagnose the three main types of damp: rising damp, penetrating damp and condensation damp, with photos to help you spot the signs. It also includes some DIY tips to help deal with smaller damp problems.
Please also visit our new ‘Solutions‘ page which explains in detail how Newton Damp Proof Membranes can help to permanently solve penetrating damp and condensation damp, and act as a rising damp treatment. Damp proofing problems such as rising damp and penetrating damp lead to damp walls, and can seriously damage your property. Even minimal damp penetration or rising damp will cause discolouration to surface plaster, decorations and can even affect a building’s structural integrity. Damp problems can also be bad for our health, aggravating respiratory problems and encouraging the emergence of mites and mould. In many cases, damp can be made worse due to poor maintenance. Newton Damp Proof Membranes act as a once-and-for-all damp walls treatment.
If you need a good Damp Proofing Specialist, ring us on 0800 068 0122 and we will put you in touch with one of our recommended damp proofing experts, free of charge. We have not just the best damp proofing systems but the best contractors to diagnose your problem, design your system and then install Newton Damp Proof Membranes to the very highest standard. Though our damp proof membranes can be installed by a skilled builder, if you are in any doubt we would recommend one of our professional installers who are highly experienced at fitting the material quickly and thus cost effectively. A damp proofing specialist would also be able to provide you with a guarantee for installing the Newton Damp Proof Membranes.
If you have a below ground damp problem – like a damp basement – we can advise you on the best waterproofing solution. Our Newton System 500 is widely recognised as the premium waterproofing membrane system available and the preferred choice for professional specifiers and waterproofing contractors. For further information please visit www.newton-membranes.co.uk, or ring us for free technical advice. We operate a scheme called Newton Basement Waterproofing Contractors (NSBC), an elite group of professional waterproofing contractors who work in partnership with Newton’s to provide the specifier and their clients with the highest quality products, design and installation available.
John Newton & Company is a market leader in the manufacture of top quality, innovative and highly reliable waterproofing and damp proofing solutions. Whether a damp wall needs treating, or a full basement waterproofing system is needed, we can put you in touch with the best damp proofing or waterproofing company in your area.
Mr Edwards from Hull said “I found the Guide To Diagnosing And Treating Damp Permanently a very informative document. It helped me to identify the type of damp problems in my home, and even suggested some DIY remedies. I would recommend it to anyone who wants to learn more about treating damp”

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.

Newton 503 Mesh Cures Aggressive Damp Penetration Externally In An Exposed Seaside Cottage

Newton 503 Mesh being installed to the walls
Talmine Cottage is located on the edge of the coast of Tongue Bay and the Atlantic coast. The stone structure was suffering from aggressive damp penetration from the elements. The penetrating damp meant that driving rain and salt air was forcing its way through the structure. The client had tried repointing the stonework, using traditional lime mortars, but this did not prevent the ingress of the damp penetration.
Extensive boroscope and infra red surveys of the cottage showed that there
was no infill of the cavity, which was the traditional means of construction at the time of the build. This meant that the driving rain was soaking through the external stone leaf and filtering through to the internal finishes, without impediment, leading to aggressive damp penetration. [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.

How Do I Deal With Penetrating Damp?

Newton 503 Mesh being installed
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.
Newton Damp Proofing Systems are a range of High Density Polyethylene and Polypropylene membranes which are moulded into a stud formation. The damp proof membranes prevent any moisture and moisture vapour

Here Newtonite is being installed to treat a damp wall
Damp walls result in a number of detrimental effects to internal finishes such as staining and discolouration, peeling paintwork/finishes, blown plaster, salt and oil contamination etc. Being a Damp Specialist Company with some 160 years worth of trading, know-how and experience behind us means that Newtons have developed damp treatment products that provide total protection to the internal finishes against these wall damp associated 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.

Can Newton Membranes Be Used Externally?
Used externally Newton Membranes provide a damp proofing solution, a waterproof support for rendered finishes and effective protection to exposed buildings, porous and deteriorated surfaces against wind driven rain, salt laden air, wall damp and general penetrating dampness. By acting as an external wall coating, it can provide as a solution for damp walls internally.

Newton 503 Mesh Used Externally
Once in place the membrane forms an exterior wall coating, which protects the structure against any further penetrating dampness whilst the membrane stud profile maintains an air gap in to which residual moisture can evaporate and where ventilation can take place. [Read more]
