Dornit geotextile is a non - woven needle - punched environmentally friendly material.
Possible sizes of geotextile rolls: 3 * 100 meters, 6 * 100 meters.
Possible densities of geotextile fabric: 150, 160, 200, 250, 300, 400.600
Scope of geotextile Dornit:
* landscaping (laying paving slabs, arranging lawns);
* construction of roads and railways, bridges, tunnels, embankment reinforcement;
* construction of pipelines (insulation);
* production of roofing roll bitumen - polymer materials (base);
* construction of hydraulic structures (reservoirs, canals, pools);
* housing and technical construction, roofing;
* Automotive industry (heat, noise insulation);
* manufacturing of filters;
* agriculture (covering materials).
Dornit geotextile is an environmentally friendly nonwoven fabric made of endless fibers (monofilament) by needle - punched method, which ensures its high chemical resistance, resistance to thermal oxidative aging.
The main functions of geotextiles are separation, reinforcement, filtration, drainage.
Working temperature range: - 60C + 100C. The structure of the material provides good strength and filtration properties.
The main advantages of Dornit geotextiles:
* high modulus of elasticity, due to which non - woven geotextiles can take significant loads and perform the function of reinforcement with relatively small deformations;
* high tensile strength (with a material density of 300g / m2 - breaking load along the length of at least 480 N, and at the width of at least 580 N);
* high coefficient of stretching (depending on the type of geotextile - up to 100 - 120% );
* the universal filtering ability of Dornit® geotextiles, due to the specific structure of the nonwoven material, which excludes the introduction of soil particles into the pores and their clogging;
* the material is resistant to ultraviolet radiation, thermal oxidative aging;
* non - woven synthetic fabric is not subject to decay, fungi and mold, rodents and insects, root germination;
* environmentally friendly material.
Dornit geotextile is used to protect butyl rubber foil (epdm membrane) prior to lining the foil. It protects the film from damage from sharp objects, roots located at the bottom of the pit.
