Use Roxil Coloured Wood Preserver to pre-treat absorbent hardwoods and softwoods. Eliminate the risk of woodworm, fungi, algae, lichen and mould with his powerful preservative. It penetrates deeply into timber to increase its lifetime. Roxil Coloured Wood Preserver is a primer and should be over-coated for ultimate wood protection. Biological growth takes many forms. The surrounding atmosphere is thick with…

Wet rot poses the biggest threat to unprotected garden wood. For sheds, wooden patio decking and trellis panels, its presence can be a death sentence. The best wood protection strategy is always preventative. Find out what causes wet rot and the best wet wood treatments and wood rot treatments in this article.

The level of protection required is shown on the maps that accompany BR211. Plots located in light grey areas require basic radon protection and plots located in dark grey areas require full radon protection. However it is sometimes possible to adopt a lower level of radon protection than that indicated by the map if a BR211 radon report for the…

Radon is a heavy, radioactive gas that is produced as a decay product of Uranium238, a metal that occurs naturally in certain types of soil and rock. Normally levels of radon in the air are not high enough to cause a significant risk to human health. However high levels of radon can build up when houses and other buildings are…

In some cases, the basement tanking system will provide adequate protection against the radon ingress. However, where a radon measurement reveals levels of radon above the recommended action level, remedial measures will usually be required. The BRE identify six main methods of reducing the amount of radon entering a house with a cellar or basement.

In 2019, the UK government made a commitment to reduce CO2 emissions to net-zero by the year 2050. This policy was a revision of previous commitments to reduce emissions levels to below 20% of the emissions of the year 1990. As part of the effort to meet this more ambitious target, the government has overhauled and stepped-up its approach to…

Depending on the type of piles used, reinforced concrete or sprayed reinforced concrete will need to be applied on top of the piles to consolidate them and provide a suitable surface for the waterproofing system. The waterproofing system used could be a cavity drainage system (Oldroyd Xv 20), a crystalline active water-proofer (Drybase Crystalline Active Tanking Slurry), or preferably a…

Drybase Crystalline Active Slurry powder is sprinkled onto the wet concrete slab after the initial set. It is then power-trowelled into the surface, imparting waterproof properties to the slab. A summary of the dry sprinkle method of application is given below:

Drybase Crystalline Active Slurry offers a solution to this problem. Because it penetrates into the concrete pile head or pile cap rather than forming a waterproof layer on top, the waterproofing material can support the loads from subsequently poured ground beams or foundation slabs. An example of a typical application is shown below, however, because piled foundations vary widely in…

The above design should detail proprietary components for waterproofing complex junctions in basement waterproofing projects. Any basement design should also include the correct method and details to form all joints and junctions when using cavity drainage membranes. This design ensure junctions are correctly lapped and sealed in accordance with the manufacturer’s recommendations. This includes the junctions between:

According to BS 8102:2022, basement waterproofing system materials fall into 3 main categories (referred to as ‘Types’). Safeguard Basement Systems are combination Type A and C waterproofing systems. This means that there are multiple barriers to water ingress. In the unlikely event that one system should fail, there is always a supporting system to prevent water ingress.

The expansion caused by wall tie corrosion can force apart mortar joints – causing cracking of masonry. Other symptoms include bulging of walls and the lifting of roof edges. In severe cases wall collapse has even been reported. Wall tie corrosion is particularly common in buildings in coastal areas (due to salt-laden driving rain) and in masonry that has…
