Separation of soil layers is solution for prevention of interpenetrating of coarse fraction and soil, prevention or slowdown of erosional processes of soil, prevention of damages of layers made from other materials (waterproof films).
Filtration is soil particles removal prevention.
Drainage is speeding up of water removing process. Depending on a field of application - improvement of efficiency of drainage layers, acceleration of consolidation of soils with high level of humidity, possibility of interruption of capillary lift of water. The main characteristic (for the drainage) of the geotextile is the filtration coefficient, which is from 20 m/day or more.
Reinforcement is strengthening of building structures by means of redistribution of stresses from vehicles or its own weight. Depending on the area of application, the stiffness of the embankment, the stability of slopes, the bearing capacity of the base increase; unevenness of shrinkage decreases.
Geotextile is multifunctional material with wide range of application in different spheres of road, hydro technical, low-height constructions and land redevelopment on different soils at different natural climatic conditions. We suggest you to familiarize with the basic spheres which non-woven needle-punched geotextiles are used in.
Therefore, you can buy needle-punched geotextile and it will be useful for the following tasks solving:
|Coefficient of permeability, in perpendicular to plane direction, at pressure 2 kPa, m/day, minimum||55|
|Relative elongation at maximum pressure, %, maximum||100|
|Surface density, g/m²||350|
|Tensile strength, kN/m, crosswise||18,00|
|Tensile strength, kN/m, longwise||19,00|
|Thickness at pressure 2 kPa, mm||2,00|
