Atmospheric pollution

Atmospheric pollution & general grime is a particular problem in built up areas, such as city centres, where there is a high volume of traffic. This is because vehicle exhausts emit sulphur dioxide which reacts with stone, forming calcium sulphate crystals on the surface. These crystals trap pollution creating a black crust - the dark staining so often seen on buildings. Not only is this unsightly, it also clogs up the pores and affects the movement of water in and out of the stone which can in turn cause it to further deteriorate.

Atmospheric pollution  Cleaning

Cleaning

The method of cleaning will depend on the substrate to be cleaned. Our equipment has a range of operating modes making it extremely flexible. Being able to adjust both pressure and temperature allows us to deliver the most appropriate cleaning method and achieve the best possible results every time.

Atmospheric pollution  Prevention

Prevention

If you are in a built up area where there is a high volume of traffic atmospheric pollution is a fact of life. Regular cleaning will help protect the substrate and prolong the life of the building.
