geomembrane
material is a smooth sheet of primary high grade high density polyethylene with stabilizing additives and prikatannym from two parties of a non-woven synthetic material based on polypropylene. Must have excellent chemical resistance, flexibility, strength, stretching and bursting. Group on flammability of material must be higher than the G3. Nominal sheet thickness shall be not less than 1.5 mm. Deviation from a thickness should not exceed 10%. Tensile strength, kN/m, not less than 40. Elongation at break,%, not less than 700. Resistance to puncture, n, not less than 480. Loss of strength after 30 cycles of freezing and thawing% from the reference value does not exceed 10. The material must be water vapor. Dimensions should not be more than six metres wide and 100 metres long. Geomembrane He should have on the canvas surface cracks, holes, tears, folds and other defects. Geomembrane shall conform to the technical requirements of GOST r 56586-2015 "waterproofing Geomembrane polyethylene roll. Technical conditions "and (or) tu (HUNDRED) manufacturer.

Geotextile fabric
non-woven needle-punctured Geotextile for construction-this must be a non-waterproof material, with high ability to filter. The cloth should be made of 100% polypropylene or polyester monofilaments snow-white colour without any inclusions. The presence of a large number of pores and the diversity of their size make the canvas a great filter material that is not zailivaetsja. Canvas structure should provide resistance to the introduction of particles of soil pores of the material. The cloth should not be prone to rot, fungi, mould, rodents and insects, germination, roots should be resistant to UV radiation. Technical characteristics of the material requires the following: surface density, GR/m2, at least 300, with deviation from the nominal target no more than ± 15%. Tensile breaking load (50 100 mm), kN/m, longitudinal/transverse direction, no more no less than 9/16, respectively. Elongation at rupture,% cloth, shall be less than: along the 80, across 120. Filtration coefficient, m/day. (Pa not less than 2 kPa), not less than 20. Thickness in mm (when Pa is not less than 2 kPa) of not less than 1.3 and no more than 3. The material should be stable, it must be able to withstand the alkalies, acids not less hydrogen indicator (Ph) than in the range of 5 to 9. Non-woven needle-punctured geotextile on technical requirements must conform to GOST 33068-2014 geosynthetic materials for drainage systems. General technical requirements "and (or) tu (HUNDRED) manufacturer. Collapse
