Zerophycol has been specifically designed to hinder plants from growing back in areas bearing light traffic (roads for light vehicles, parking lots, cycle paths, pedestrian lanes, paths through cemeteries etc.) without the need for herbicides.
Zerophycol’s structure fosters drainage. It does not retain rainwater and therefore makes it difficult for plants to take root and grow.
Non-bound aggregate on the surface makes it easy to maintain and remove the rare greenery that may appear.

Zerophycol is an eco-responsible solution developed by Colas to reduce the use of phytosanitary products.
Zerophycol therefore provides an alternative solution to phyto-pharmaceutical products, catering for increasingly demanding environment regulations (such as the loi Labbé in France for local administrations, due to be extended to
many private facilities as of 2022).
