Drainage geocomposite Slavros Drainage 9

Description

The drainage geo-composite of the Slavros-Drainage brand is a three-layer material with a core of plastic mesh formed by strands superimposed on each other, creating channels for draining liquids and gases providing high and stable water permeability in the plane of the canvas. Geotextile is attached to the grid on both sides as a filter and to protect the channels from clogging with soil. The coating is a synthetic nonwoven material (geotextiles) on both sides with a geomembrane on one side.

Areas of use:
  • drainage of solid waste landfills and PO;
  • mining industry facilities;
  • areas with a large influx of water into the drainage layer (no more than 0.007 m3 / day per 1 m² of area);
  • reconstruction sites with the broadening of the carriageway in conditions of unsecured elevation of the bottom of the pavement above the groundwater level (long standing surface water);
  • areas of reconstruction with widening of the carriageway, when it is technologically difficult or technically impossible (low embankments) to increase the thickness of the sand drainage layer of the pavement widening with the deepening of its base below the surface of the existing pavement;
  • anti-erosion protection of slopes, excavations, trenches;
  • road sections of high technical categories with improved capital types of coatings at 2-3 types of terrain in the II-III roadclimatic zones, if the roadbed is composed of silty soils;
  • Weakened areas prone to frost-heaving sections of roads (creation of transverse overhangs within the curb during repair and maintenance of roads).
  • Highly effective and economical alternative to traditional drainage systems from crushed stone. The drainage composite consists of a volume "Slavros - Drainage" geogrid and a filtering nonwoven fabric attached from 2 sides.

Material advantages:
  • slight deformation of the material. (Large loads arising from the pressure of the soil or work during compaction, slightly reduce the watercarrying capacity of the mats);
  • high chemical resistance. (The grid from polyethylene of low pressure and nonwoven polyester geotextiles has high chemical and biological resistance);
  • cost savings. ("Slavros" drainage mats with a fairly small thickness and good water-carrying capacity, as well as drainage crushed stones, significantly reduce the cost of excavation and laying of crushed stone);
  • high water carrying capacity. (The water-carrying capacity of “Slavros” drainage mats corresponds to a layer of crushed stone 10–15 cm high);
  • low weight (One roll of drainage mat weighs about 45 kg, and replaces up to 25 tons of crushed stone);
  • simplicity of work with mats.
