FIELD: manufacture of building materials.
SUBSTANCE: material is made from principal composition containing polyethylene (mixtures of polyethylenes) and rubber crumb and, additionally, ethylene/vinyl acetate copolymer with vinyl acetate content 10-24% and characterized by melt flowability 10-18 g/10 min. Rubber crumb represents vulcanized waste with particle size 1.0-1.4 mm, which allows obtaining rubber-polymer material capable of being processed into granules and designed to be processed via jet molding into building materials such as large-size tile sheets.
EFFECT: enlarged choice of inexpensive building materials.
