Characteristics required for use in drainage systems.
EN ISO standards define the filtration as the process that is used to retain the particles of the ground subject to hydrodynamic forces and allow the passage of fluids within the geotextile". The opening characteristic of the pores of Hipertex® is designed precisely to retain the particles and allow free movement of the water. Without this condition, the migration of the soil could reduce the bearing capacity of the construction. Hipertex® has replaced the classic gravel filters drainage into dewatering trenches, along the river banks, in the reservoirs, foundation walls, and athletic facilities. Our articles are designed to allow liquids to pass in the draining systems as in the micropore tubes and at the same time to retain the finer particles while avoiding their migration into the drainage."
