Efficiency and scope of application

Woven geotextile by Geospan TN is produced on weaving equipment from durable polypropylene fibers, the basis for which is primary high-quality raw materials. Thanks to the proven production technology, raw materials, the materials have high strength, low elongation, which enables the materials to be used as separating-reinforcing layers to increase the bearing capacity of roads, embankments and other structures.

Can be effectively used in acidic or alkaline soils (limestone, alkaline, clayey soils, etc.). Geospan TN reinforcing geotextiles are resistant to ultraviolet radiation, water, fungi, rodents, insects, plant roots, vibration, temperature changes and other external influences.

The use of Geospan TN enables to:

  • extend the service life of pavement, increase overhaul intervals and reduce operating costs;

  • reduce construction time;

  • increase the resistance of coatings to dynamic and static loads, reduce the rate of occurrence of rutting, cracks, potholes, and dents;

  • simplify and speed up work with weak soil;

  • eliminate the risk of uneven subsidence and frost heaving of the soil;

  • reduce the time of consolidation and the value of the settlement of the embankment;

  • carry out construction on soft soils, swamps of any type or in permafrost conditions;

  • enables you to replace the chemical methods of stabilizing bases;

  • reduce transport and storage costs due to the compactness of the material;

  • quickly organize access roads and a working area for heavy equipment.

Application scope of Geospan TN:

  • reinforcement of embankments of roads, railways, airfields;

  • reinforcing of soil foundations for construction;

  • stabilization of soil foundations during the construction of retaining walls.
