FIELD: technological processes.
SUBSTANCE: group of inventions is related to tiling material hardened in-situ with longitudinal reinforcement and method of its production. Method for production of tiling material hardened in-situ consists in provision of the first tubular element from material impregnated with resin in compressed condition as internal tubular element and impregnation of impregnated material with resin. Then coarse canvas is placed, which is selected from woven or non-woven canvas and having high strength in direction of warp at least on part of one surface of compressed tubular element. Coating made of material that is impermeable for resin is placed on tubular element and coarse canvas, in order to get external impermeable coating. Tiling material hardened in-situ includes the first tubular element of material impregnated with resin, reinforcing canvas selected from woven and nonwoven canvas and having higher strength in direction of warp. AT that canvas location is selected so that not to prevent radial expansion of tiling. Tiling material also contains external coating, which is impermeable to resin and is located around the first tubular element and canvas.
EFFECT: development of improved method to produce longitudinal reinforced tiling material, and also in production of tiling material with higher longitudinal strength.
