These are permeable and filtering materials.
Flat structures that can be woven or not woven depending on the
fact that they are formed by a regular weaving of two or more
synthetic fibres yarns sequence or by their accidental arrangement,
fixed by mechanical or thermal methods cohesion.
Applications: filtering, separation and protection of soils.
These are made of waterproof materials. They
may be synthetic (homogeneous or reinforced, Plastomeric or Elastomeric
type, LDPE, HDPE, PVC, PP), bituminous (obtained by the processing
of a melted mixture of bitumen, plastomeric and/or elastomeric
polymers with mineral charges, having a very low permeability
factor),bentonitic (made of sodium bentonite and geo-synthetics,
having the shape of a thin clay layer held by two geo-textiles
or glued to a synthetic geo-membrane).
Above all they are used to function as strengths
and they may be extruded (made by polymer materials, generally
high density polyethylene or polypropylene), a fabric (mesh shaped,
made by synthetic fibres at high modulus, generally polyester)
or "welded strips" (two or more series of fibres or
other synthetic elements connected at regular intervals by welding
Applications: Strengthening and stabilization of steep, slopes
subject to landslides, and retaining wall construction.
Geo-mesh, Geo-mat, Geo-cells, Geo-composite,
Application: Erosion control, surface stabilization and dumps
