Geotextile "Dortex" (Dornit) manufactured by S.M.F.-System is an environmentally friendly geotextile material, which is a water-permeable polyester fiber fabric produced by needle-punching technology.
Due to this, Dortex geotextiles have high chemical resistance and resistance to thermal oxidative aging. Dornitus is not susceptible to decay, fungi and mold, rodents and insects, root germination. The operating temperature range of "Dortex" is from -60 to +130 degrees Celsius, due to its structure it has good strength and universal filtering properties.
The canvas "Dortex" is structurally dense and has a high modulus of elasticity, which allows it to perceive significant loads and perform the function of reinforcement. Its portable tensile loads are at least 400 N in length and 500 N in width. In addition, elongations at rupture are up to 45%, that is, with local damage, there is no destruction of the material, and it continues to perform its functions.
"Dortex" is an environmentally friendly material, resistant to ultraviolet radiation and does not form any by-products even during a long stay in the ground. Thanks to all of the above, Dortex geotextiles are an ideal material for use in the territory of the Republic of Kazakhstan with its variety of geological and climatic conditions, seasonal fluctuations in temperature and humidity. The technical characteristics of the canvas make it an almost universal material, allowing its use in the widest range of works.
