Damp Proofing Solutions – help and advice
Damp problems such as rising damp, condensation or penetrating damp can cause problems to internal wall finishes and contribute to a damp unhealthy environment within the habitable space. A permanent solution is essential for the prevention of damp floors and walls.
There are many different causes of damp within our homes, not just rising damp, which is the type of damp often associated with damp proofing. The following information should help you identify the types of damp that occur in buildings and the damp treatments that are available.
This is when water from the ground rises through the brickwork, stonework or through the mortar. It is unsightly and unhealthy, usually a problem in houses built pre 1925 when damp proof courses were not commonly installed. It is less common in modern properties, but can occur where the original damp proof course has become damaged or the ground level around the property has been raised with the addition of paths, flower beds or driveways, which have bridged the original damp proof course.
Is the result of water successfully penetrating horizontally from the outside of the building through the fabric of the wall. It can affect all buildings and is most commonly caused by problems with the roof, brickwork or windows – leaky pipes, blocked gutters, defective pointing or poorly maintained brickwork. It can be damaging even if it does not penetrate all the way through a wall, potentially leading to more serious problems such as dry rot, wet rot or structural damage.
This is the most common form of dampness within a building, and can cause unsightly black spot mould patches, peeling paint work and a musty smell. Condensation happens in almost every property as a result of the moisture created by everyday living, from breathing to boiling the kettel, moisture is present in the warm atmosphere of your home and when the structure cools down the moisture condenses and settles on the cold internal surfaces.
Newton System 800 is a range of BBA approved damp proof membranes and ancillaries which are quick and clean to install and offer a permanent solution for treating damp walls.
- 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 damp wall and the new finish
- Significantly prolong the life of the internal finish whilst still allowing for natural evaporation of dampness from the structure
- Highly sympathetic to buildings and are fully reversible; a requirement when treating listed buildings in the United Kingdom.
- Quick and easy to install
- Newton damp proof membranes hold BBA certification, and all our membranes are guaranteed against deterioration for 30 years and have a life expectancy of at least 50 years.
Damp proof membranes
Newton 805 Newlath and Newton 803 Newtonite meshed membranes provide a firm key and impermeable barrier on any damp or deteriorating surface ready for plaster, render or dot and dab plasterboard. The unmeshed Newton 803 is used where insulation requirements dictate the use of a timber or steel frame ready for plasterboard. Newton damp proof membranes are the ideal solution for listed buildings as they are deemed ‘reversible’.
Newton Specialist Basement Contractor Cavity Tech Ltd were contracted by this prestigious private school in Brighton to treat both rising and penetrating damp as part of its refurbishment. THe different construction elements within the structure and the space constraints also needed to be considered when designing the damp proofing solution.
BBA certified Newton 803 Mesh was mechanically fixed to the substrate by Cavity Tech using Newton Mesh Plugs, providing a physical barrier between the damp substrates and the new internal surfaces.
Some examples of Listed and Historical projects where Newton Waterproofing Systems have been used are:-
- British Museum
- Douai Abbey , Berks
- Royal York Hotel, Bath
- St Georges Hall , Liverpool
- Menin gate, Ypres.
- Windsor Palace
- Houses of Parliament
Newton damp proof membranes are ideal for accommodating a number of finishes, as illustrated in the drawings:
- 1. Newton 803 with battens
- 2. Newton 803 with metal frame
- 3. Newton 805 Newlath/803 Newtonite with dot and dab plasterboard
- 4. Newton 805 Newlath/803 Newtonite with plaster/lime plaster/render
The Newton System 800 damp proof membranes offer the potential for a range of finishes
Other Damp Proofing Products
Newton 806 CWC Thermal Paint
A white thermal coating for cold and poorly insulated surfaces. It contains specific mineral powders which, thanks to their insulating features, raise the surface temperature of the treated wall by up to 4°C, and so reduces the incidence of surface condensation.
Newton 807 BKK Water Repellent Treatment for Exposed Walls
A transparent, colourless wall coating, water and siloxane based, ideal to protect porous walls of various substrates from wind-driven rain. After treatment, the wall is deeply impervious to water ingress and therefore better protected against frost damage.
Internal Condensation and Penetrating Damp
Newton System 800 damp proofing products can be utilised in order to prevent the occurrence of penetrating damp, internal condensation and black spot mould in an existing structure.
Newton System 800 membranes, such as 803 Newtonite, provide a complete damp proofing solution when the wall and floor have been diagnosed with rising damp. The meshed surface provides a mechanical key for the direct application of plaster, render or dot and dab plasterboard.
“Newton System 800 was easily installed in a timely manner enabling the project to move forward at a pace without the need for drying out time or suffering delays from adverse weather conditions. We were able to provide the client with an insured backed guarantee for damp proofing this prestigious listed school”
