-High mechanical strength

Used to obtain sprayed waterproofing coatings intended for waterproofing metal, concrete and brick structures — the internal and external surfaces of tanks, tunnels, pools and viaducts, foundations and roofs, both newly built and reconstructed. The coating has high stability of properties and a long service life.
