FIELD: process engineering.
SUBSTANCE: invention relates to construction, particularly, to production of finishing materials. Nonwoven geotextile is used as a substrate. Layer of hardened bulk comprises pebble gravel preprocessed by epoxy paint and mixed with polymer binder at 4:1 ratio. Said epoxy paint comprises epoxy resin, thickener and pigment or mineral dyestuff. Polymer binder represents a water-dispersion acryl or polyvinyl acetate or epoxy material. Hardened bulk layer thickness consists of the mix pebble gravel preprocessed by epoxy dye and polymer binder equal 2-7 mm. Hardened bulk layer face surface is coated with polymer binder layer diluted in water at 1÷10 ratio.
EFFECT: high durability, flexibility and vapour permeability, simple composition and production.
