Geocomposites are unique materials, combining different types of geosynthetics. They possess excellent operational and physical characteristics peculiar to those types of raw materials that are available in their composition. The modern market offers several varieties of this material. Each of them has its own characteristics and scope of use.
Main types of geocomposite materials
The specified production is classified as follows:
Geogrids-geotextiles. The material has reinforcing properties. With its help, it is possible to separate fractional types of raw materials. It is an effective filter. In the production of this product, different geogrids are used - woven and extruded. Geotextile often acts as a tool that facilitates easier installation. This property is applicable, as a rule, to composite materials intended for reinforcing layers of asphalt and concrete.
Geotextile geomembrane. The components of this material perform different functions. Geotextiles have filtering properties, and geomembrane - waterproofing. In addition, the latter opens a free space for the circulation of water or gas in the cavity of the geocomposite ball. Widely distributed this product was obtained with the arrangement of drainage structures of vertical or horizontal type, in the organization of gas removal systems, in the process of reclamation of territories where waste products are buried.
Geotextile-rigid core-geotextile. Geosynthetics, which has waterproofing and protective functions. A rigid core can be made from 2-3 rigid extruded directional meshes or elastic polyamide profiles. The coating is used to create drainage systems for any structures.
Key Benefits of Geocomposite Materials
The use of these reinforcing and waterproofing materials gives a lot of positive moments. They are included in the following factors:
- possibility of significant financial savings - culvert characteristics of geocomposites are similar to those of the previously used crushed stone. The cost of the first is lower than the cost of excavating and laying fractional raw materials;
- a high speed of laying, achieved due to the convenient form and a small weight of geosynthetics;
- minimum level of deformation - when large loads occur, typical for sealing stages, geocomposites only slightly lose culvert quality.
- High speed of conjugation of different layers with the base;
- reliable protection of mineral raw materials from silt formation, which is achieved due to the filtering properties of the geocomposite located on top;
- hardening of the pavement, which is provided by reducing the soil moisture level;
- minimization of the thickness of the drainage balls by means of an operative drainage of moisture.
