The pore structure and permeability of some geotextiles are similar

To keep the soil aggregates, or particles, designed to prevent significant movement is limited to a reasonable classification. However, the whole is too thick, drainage, soil, soil particles are too large to bridge over the gap between the rocks, if the aggregate interface. Soil, i.e., the pore structure of the soil pipe and some geotextile filter permeability to water is similar to the classification of the total eroded soil particles Wu will lead to a lack of restraint. Adjacent to the water in the soil while allowing free flow of particles in this textile preservation of the soil interface can provide the same damage. geotextile drain filter is therefore required to remove the overall classification.

Fibers by the action of the waves and the current along the coast inland drainage embankments and washed with salt water to prevent soil drainage, because if you are using fabric that does not require a special aggregate gradation is more severe erosion, instability, and can cause destruction of the slopes . To prevent soil erosion, earth slopes, often in spite of armor, armored cover is applied, erosion is still undermining the basis of body armor, will occur. To ensure long-term stability and performance, and erosion control structures, the barrier shielding the soil surface to be purified. Soil moisture away from the barrier to the accumulation of non-hydrostatic pressure must be permeable so that the slopes can be penetrated. Traditionally, a special grade of sand, gravel, or stone armor on the down slope of the particle filter has been used to prevent erosion. However, particle filters are expensive, and can not be used, especially locally, even if properly installed, the erosion of power, you can eat them washed away. Some woven geotextile are ideal for erosion control barriers.
 
Erosion of soil erosion control fabric on the slope will force the water in the flow of shielding; they are permeable and, therefore, are free from seepage of water through a pardon. Long armor stone of this fabric as it is covered with soil to keep the slopes will be retained. See also: earthwork construction and soil erosion in mining operations, serious erosion of plant protection, temporary slopes that are not removed, will occur. Amount of sedimentation downstream of the results, for example, serious injury, polluted waterways, sewers, clogging, or precipitation-covered forests and grasslands may occur. From federal and state agencies to recognize the problems associated with precipitation and sedimentation control, the amount of any disturbance in the area has passed a bill that requires. Thus, the earthwork contractor and the mining company's responsibility and cost to control sediment discharge are facing in the workplace. reinforced earth walls.
