Geotextile are permeable fabrics which, when used in association with soil,树池钢格板-barbed iron wire, have the ability to separate, filter,hexagonal wire meshes, reinforce, protect,浸塑电焊网, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (looks like mail bag sacking), needle punched (looks like felt), or heat bonded (looks like ironed felt).
Geotextile and related products have many applications and currently support many civil engineering applications including roads, airfields, railroads,wire mesh-Galvanized Iron Wire, embankments,basket ball fence, retaining structures, reservoirs, canals, dams,wire mesh product-barbed iron wire, bank protection, coastal engineering and construction site silt fences. Usually geotextiles are placed at the tension surface to strengthen the soil. Geotextiles are also used for sand dune armoring to protect upland coastal property from storm surge, wave action and flooding. A large sand-filled container (SFC) within the dune system prevents storm erosion from proceeding beyond the SFC. Using a sloped unit rather than a single tube eliminates damaging scour.

In building demolition, geotextile fabrics in combination with steel wire fencing can contain explosive debris.
Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Overall, these materials are referred to as geosynthetics and each configuration-geonets, geogrids and others-can yield benefits in geotechnical and environmental engineering design.
Geotextiles have been used to protect the fossil hominid footprints of Laetoli in Tanzania from erosion, rain, and tree roots.
Erosion control manuals comment on the effectiveness of sloped, stepped shapes in mitigating shoreline erosion damage from storms. Geotextile sand-filled units provide a “soft” armoring solution for upland property protection. Geotextiles are used as matting to stabilize flow in stream channels and swales.

Geotextiles can improve soil strength at a lower cost than conventional soil nailing.[citation needed] In addition, geotextiles allow planting on steep slopes, further securing the slope.
Coir (coconut fiber) geotextiles are a popular solution for erosion control, slope stabilization and bioengineering, due to the fabric’s substantial mechanical strength.App. I.E Coir geotextiles last approximately 3 to 5 years depending on the fabric weight. The product degrades into humus, enriching the soil.
