We are often called out to resolve an issue with cars or people slipping on concrete or natural stone surfaces or paving in damp shadowed areas around the house, or even in commercial settings.

Typically, driveways or outdoor paths and entertaining areas make up the bulk of these call-outs. Often we will provide an economical solution as simple as high pressure removal of the lichen and moss contamination that has built up over time.

After long exposure to moss and lichen, natural stone will also be damaged, these living organisms contribute to mechanical weathering (as well as chemical weathering).

Lichens and mosses grow on essentially bare surfaces and create a more humid chemical micro environment. The attachment of these organisms to the surface enhances a chemical breakdown of the micro layers of the rock and will nearly always create an unsafe and unstable surface. High pressure cleaning will remove this structure.

moss removal3This high pressure cleaning solution involves a water jet pressure around 4000psi (well beyond domestic pressure washers) which actually removes the root structure embedded in the surface, because unless removed completely this remaining structure forms the fertilizer and purchase for subsequent outbreaks. We then treat the surface with a commercial grade Sodium Hypochlorite which will sanitize and inhibit regrowth for months as well as enhancing the natural colors.

Although one High Pressure Cleaning should be sufficient we recommend the re-application of inhibitors particularly through the winter months or on areas that remain in constant shade or remain damp for extended periods.
