Combined Geogrid with Geotextile

    Description

    Combined Geogrid with Geotextile is a polypropylene extruded biaxial geogrid with a non-woven needlepunched geotextile bonded to one side.

    Description of Combined Geogrid with Geotextile

    Combined Geogrid with Geotextile is an engineered geogrid designed for soil stabilisation, separation and reinforcement applications. Combined Geogrid with Geotextile is manufactured from Polypropylene through the process of extruding, longitudinal and transverse heat stretching. Geotextile is then heat bonded to the grid to form a sound composite structure.

    It is designed to prevent reflection cracking, water damage and improve load capacity in road construction and renovation. It has the property of high temperature resistance and anti-fatigue cracking and therefore extending the life and time of asphalt pavements.
