EROSION CONTROL WORKS

In coastal and river bank erosion control structures against the action of waves and currents, permeable revetments are often used. These are rocks, or artificial elements like concrete blocks or gabions. Under this covering layer, the fine particles of natural soil are subjected to drag forces generated by hydraulic gradients. A filtration system between the revetment and the base soil is therefore to be designed. The hydraulic characteristics of this system must ensure an adequate retaining capacity of fine soil particles, allowing in the meantime the water to pass through, without generating dangerous pressures on the revetment.

GEO nonwoven geotextiles are used for this purpose as filtration layer, offering adequate retaining capacity and permeability normal to their plane. The site conditions may be more or less critical for the geotextile, according to the type of revetment, to the characteristics of base soil and according to the drop height of covering elements. GEO nonwoven geotextile offer high mechanical resistance and energy absorption capacity, which make them suitable to be used also in critical conditions of installation.




USE OF NONWOVEN GEOTEXTILE:

Separation layer between base soil and revetment.
