Geotextile


  • From Wikipedia, the free encyclopedia

 

Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or heat bonded (resembling ironed felt).

Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Geotextiles are able to withstand many things, are durable and is able to soften a fall if someone falls down. Overall, these materials are referred to as geosynthetics and each configuration—-geonetsgeosynthetic clay liners, geogrids, geotextile tubes, and others—-can yield benefits in geotechnical and environmental engineering design.


  •  Applications

Geotextiles and related products have many applications and currently support many civil engineering applications including roadsairfieldsrailroadsembankmentsretaining structuresreservoirscanalsdamsbank protection, coastal engineering and construction site silt fences or geotube. 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.

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.[3][4]

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.

Geotextiles have been used to protect the fossil hominid footprints of Laetoli in Tanzania from erosionrain, and tree roots.[5]

In building demolition, geotextile fabrics in combination with steel wire fencing can contain explosive debris.[6]

Coir (coconut fiber) geotextiles are popular for erosion control, slope stabilization and bioengineering, due to the fabric's substantial mechanical strength.[3]:App. I.E Coir geotextiles last approximately 3 to 5 years depending on the fabric weight. The product degrades into humus, enriching the soil.[7]
