Geotextiles and geomaterials are synthetic, permeable fabrics designed to separate, filter, reinforce, protect or drain soil. Typically made from polymers such as polyester, polypropylene or polyethylene, these geosynthetic materials offer many benefits to society. Get more info visit stsgeo-krd.ru.
Woven fabric, also known as geotextile, is the most widespread type. This material is created by interlacing two or more sets of strands at right angles; they may be flat or round and made up of slit films or monofilaments.
Non-woven geotextiles differ from woven fabrics in that they are created by bonding continuous yarn filaments or short staple fibers together using thermal, chemical or mechanical techniques. They're commonly used for preventing clogging in sewage pipes as well as asphalt pavement overlays and erosion control applications.
Geotextile filtration properties are determined by their ability to promote the lateral flow of water, dissipating kinetic energy from capillary rise in groundwater. A variety of geotextile designs exist for this application, but the most basic involves permeability and strength combined. The first successful use of geotextiles in this manner was documented back in 1950s when R. J. Barrett employed them under precast concrete seawalls and erosion control blocks.
