Geotextiles
GeoTextiles Function
Separation
Alyaf Geotextiles separate two dissimilar materials so that the integrity and functioning of both the materials can remain intact or be improved.
For example: Alyaf geotextiles used between subgrade and base course prevent the intermixing of the two layers thereby preserving the integrity of the base course.
GeoTextiles Function
Filtration
Alyaf Geotextiles permit an unimpeded flow of water while its structured pores provide depth filtration to restrain migration of soil fines.
For example: Alyaf geotextiles allowing an unimpeded flow of water into the driainage media while preventing the migration of the soil fines.
GeoTextiles Function
Protection
Thick Alyaf Geotextiles provide an excellent medium to absorb the point stress and improve the puncture resistance of geomembrance.
GeoTextiles Function
Lateral Drainage
The 3D structure of thick Alyaf geotextiles provides an avenue for lateral drainage of water and gasses along the plane of the fabric. This function is especially significant where the geotextile is required to transport water along its own plane, as in tunnel lining and waste containment systems.
GeoTextiles Function
Moisture Barrier
Alyaf Geotextiles separate two dissimilar materials so that the integrity and functioning of both the materials can remain intact or be improved.
For example: Alyaf geotextiles used between subgrade and base course prevent the intermixing of the two layers thereby preserving the integrity of the base course.
GeoTextiles Function
Reinforcement
This is the synergistic improvement of a total systems strength created by introduction of geotextile into a soil development primarily through three machanisms.
Lateral restraint of base and subgrade through friction between aggregate, soil and geotextile.Increase in the subgrade bearing capacity by forcing the potential bearing capacity failure surface to develop at alternate higher shear strength surface.Membrane type support of the wheel loads.
