Rock and concrete ageing
The visual impact created by mountain and hill quarries, concrete walls and rock cliffs, which have been built to retain embankments or sloping terrains, are conveniently treated with non-toxic mineral salts in order to precede the slow work of nature. Reacting by oxide reduction with the minerals contained in the rock mineral salts accelerate the ageing process. For treatment to mitigate the visual impact we do not use substances which could be toxic to humans, animals or the environment.
