Geotextile Dornit - characteristics , scope and cost of

Polymer paintings under the title geotextile known not so long ago.But their unusual properties of products have already won a lot of popularity, and it has become widely used in many areas, including in the home.With one of the varieties of synthetic material - "Dornit" - we get acquainted in detail, examined its characteristics and applications.

Edition canvases "Dornit" engaged in several companies on different technologies, so the following characteristics - generalized, since according to the manufacturer may be some variation in the in one direction or another.

Features "Dornit»

There are several technologies of manufacturing of geotextiles."Dornit" - mostly non-woven fabric, which is based on polypropylene.The micropores in the case materials needle-punched method.Woven analogue is less common (on the basis of polyester fiber - a better option) and not much of it (on the main characteristics, the specifics of the application) is different, except manufacturing technology (weave).

main function of material - drainage (filtration) + reinforcement (reinforcement).In

sale "Dornit" comes in rolls, usually a length of 50 to 150, a width of 1.5 - 5.3 (m).The main purpose (as well as any of the polymeric and liquid-permeable fabric) - the creation of the separation barrier between dissimilar environments and materials.

Properties domestic geotextile

main characteristics of the material

1. Density (g / m²) - from 90 to 1200.
2. Thickness (mm): 1.7 - 4.7.
3. filtration rate (m / day): 80 - 140.
4. strength (H): 400 - 1650.
5. maximum elongation depending on the load vector (%): 100 (longitudinal) and 130 (cross).
6. «Dornit" does not change its characteristics in a temperature range from -60 to +100 ° C.
7. minimum operational period - 25 years.

Scope Dornit

recommended density of matter is indicated in parentheses in the "g / m²."

Road construction (300 - 600)

«Dornit" acts as a separating layer between the sand (gravel) and soil.This makes it possible to reduce some consumption bulk materials and increase the longevity of the roadway (excluded the appearance of cracks in the coating).Consequently, the reduced cost of 1 km of motorway.

drainage systems (90 - 150)

pipes wrapped in "Dornit" hardly clogged.This makes it possible to significantly increase the life of the next system maintenance.More improvement of the drainage system is considered here.

soil Strengthening (100 - 400)

material is advisable to lay a tile (paving), on the slopes, in the regeneration of artificial reservoirs and in other similar cases."Dornit" prevents germination of vegetation roots, leaching the soil (it reduces erosion), compensate tensile stresses, redistributing the load on the ground.

«green roof" (100)

Geotextile "Dornit", laid under a layer of fertile soil, while providing effective drainage (excluded water stagnation on the roof) and protects the soil from washing away.An added bonus - you can save on a "lining" materials.As a result - reduced load on the roof.

cost "Dornit»

Pricing depends on many factors (technology, linear parameters and the like), so it suffices to only the minimum cost of material - from 12.2 rubles / m² (at a density of 100 paintings).
