DAMP PROOFING SERVICES: WEATHERSHIELD

Penetrating damp can be a major problem for some buildings where moisture is able to find its way through walls. Although the problem can be sometimes caused by poorly maintained buildings and leaks, it is sometimes related to single skin walls with high moisture absorbency. Buildings which are exposed to harsh weather conditions may also be susceptible to penetrating damp. Moisture getting through the wall can bring the right conditions for condensation to occur and black mould to grow and can affect any part of a building. The effects of this can lead to decorative defects, odour, tide-marks, damp patches and visible patches of black mould. The effects of penetrating damp may be hidden behind wallpaper or cause it to peel away and, in some places, black mould will be noticeable. Most importantly, the spores associated with black mould can affect people’s health causing respiratory problems and, in some rare strains, secrete toxins which can lead to neurological health problems.

HOW THE WEATHER SHIELD PROTECTS

The Weather Shield forms a barrier against rain and moisture keeping walls dry from the outside. We use an industrial, double strength water repellent solution which we spray onto the external walls. As you can see from the image above which was taken around a time when there had been a significant amount of rain. The middle house has been treated with the Weather Shield, an external, breathable sealant which allows the rain to literally run off the external walls. Moisture is simply unable to penetrate and saturate. Aesthetically, when a wall is treated and conditions are dry, the Weather Shield is unnoticeable to the eye. When exposed to wetter conditions, there is a noticeable difference between treated and untreated walls. The Weather Shield repels water which runs off the surface keeping the internal wall dry. On an untreated surface the water penetrates and stays there, causing damp and interior damage.

DRY WALLS, REDUCED HEAT LOSS & LOWER ENERGY BILLS

As the Weather Shield allows the wall to dry out over time, it helps increase the wall’s resistance to heat loss and helps to lower the U value. Official research conducted by the Environmental Study Centre shows that the average house loses 35% of its heat through walls. In one of their studies, they compared a wall which was damp at ground level and drier at the top. The heat loss was 38% greater in the damp area and recorded at 21% in the drier part which is a significant difference. The application of Weather Shield to walls where penetrating damp is a major problem and walls have remained saturated for long periods prevents further saturation and allows the wall to dry out, helping cut energy bills. This is both better for home owners and better for the environment; helping reduce costs and our carbon footprint.
