All our products have been tried and tested and have proven results when applied correctly and in a professional manner. Please do not hesitate to contact us and we will be happy to advise you. Stormdry Water Proofing- Repellent: Stormdry is a colourless, breathable, water-repellent treatment for brick, concrete and stone walls. It is supplied in the form of a deeply penetrating cream that is applied to the wall surface using a roller or brush. Once Stormdry has been applied to the wall surface, it will permeate deeply before curing to form a water-repellent barrier. Typical applications for Stormdry include: •Protecting against penetrating damp (rain penetration) •Improving the thermal resistance of masonry by keeping it dry (energy saving) •Improving the performance of cavity wall insulation by protecting it from moisture •Improving flood resistance of masonry Breathable and Long Lasting Stormdry is based on carefully selected silanes and siloxanes which line the pores of the masonry to form a water-repellent silicone matrix. Because it works by lining the pores rather than blocking them the masonry is allowed to breathe and does not suffer from increased frost damage (spalling). Due to its novel formulation and deep penetration, Stormdry is resistant to UV light and other forms of degradation, resulting in a life expectancy of 20-30 years. Deeply Penetrating Stormdry is able to penetrate more deeply into masonry than traditional liquid-applied masonry water repellents. As well as increasing life expectancy this also improves Stormdry's crack-bridging ability. As the diagram below shows, Stormdry is able to provide water-repellency beyond the depth of small cracks. It should be noted that larger cracks will still need to be filled as part of the Stormdry treatment. Mortar lines may need to be repointed with a sand/cement or sand/lime mix incorporating Stormdry Repointing Additive. Stormdry has been tested to EN ISO 15148:2002 (E), demonstrating its effectiveness on concrete, mortar, brick, and sandstone. The graph below shows that the water uptake for Stormdry treated samples was considerably lower than for untreated samples: As Stormdry is formulated to penetrate deeply into masonry it can take up to two months after application for a noticeable "beading effect" to appear when rainfall strikes the wall. However, Stormdry is resistant to rain after just 12 hours. In common with most other masonry water repellents, Stormdry's beading effect will become less pronounced after two or three years. However Stormdry will continue working for 20-30 years. Improving the thermal resistance of walls through the use of conventional insulation is not always practical - particularly where older buildings are concerned. Many homes and commercial properties in the UK are built using single-skin walls, making them unsuitable for cavity wall insulation. The installation of internal insulation can be disruptive and takes up valuable living space whilst externally applied insulation is often unattractive. Fortunately, Stormdry offers a solution. It is a well-known fact that porous masonry materials such as brick, stone, concrete, and mortar are worse insulators when they are wet. By preventing the absorption of water, Stormdry ensures that the insulation properties of the masonry are maximised throughout the year. Tests carried out using Stormdry at the University of Portsmouth and subsequent SAP analysis showed that energy savings of up to 27% are possible when Stormdry is used on single-skin walls due to reductions in thermal conductivity. This has been verified in an independent report carried out by environmental consultants, Giraffe Innovation. When the effects of reduction in evaporative cooling are taken into account, total energy savings of up to 29% are possible.

Dryzone Damp Proofing Injection Cream

Dryzone When launched in 2000 Dryzone damp proofing cream revolutionised the treatment of rising damp. The patented Dryzone cream is the best-selling rising damp treatment in the UK market and has many advantages over traditional chemical damp-proof methods. Dryzone damp-proofing cream is injected into 12mm holes (drilled and evenly spaced in the mortar course) by means of a simple applicator gun. After the Dryzone cream is installed it diffuses before curing to form a water-repellent barr
