GeosyntheticsSeparation and filtration of ground layers

Separation is retention of two different ground layers (with different functions) in a structure, without allowing them to mix or impair their functions. This requirement is frequently applied for the transport infrastructure (roads and railways) or structures under the foundations. A separating layer, in many cases, is used together with reinforcing (when it is needed to increase the holding power of sub-grades) or filtrating (without allowing tiny ground particles migrate to a separate layer) layer.

Usage areas:

  • To separate different ground layers; filtration, mounting road and railway sub-grades and embankment;
  • filters of drainage systems (geotextile protects the entrance of ground particles into drainage systems, but at the same time it remains permeable to water);
  • To solve hydro-technical tasks (protection of particles, available in the slope ground, from the flushing with a water flow);
  • protection of building structures, materials from mechanical or chemical damages.
