2) Erosion control
3) Slope stabilization- Published on 20 Sep 16a. 2, 3
b. 1, 3
c. 1, 2
d. All of the above
ANSWER: All of the above
- Geotextiles are also used for sand dune armoring to protect upland coastal property from storm surge, wave action and flooding.
- 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 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 erosion, rain, and tree roots.
- In building demolition, geotextile fabrics in combination with steel wire fencing can contain explosive debris.
- Coir (coconut fiber) geotextiles are popular for erosion control, slope stabilization and bioengineering, due to the fabric's substantial mechanical strength.
- Coir geotextiles last approximately 3 to 5 years depending on the fabric weight. The product degrades into humus, enriching the soil.
