What is an Pacific GeoSource RockGrid?
Pacific GeoSource RockGrids are plastic, grid-like products delivered to a job site in roll form. Manufactured using polypropylene, these products feature high stiffness at low strain and excellent resistance to installation damage and environmental effects (UV, chemical, biological attack, etc.). RockGrids have been used successfully in roadway applications for more than 30 years.
How do Pacific GeoSource RockGrids work?
Pacific GeoSource RockGrids are manufactured such that their ribs and apertures form an integral structure. This facilitates “mechanical interlock” as larger aggregate particles partially penetrate through the RockGrid’s apertures. Once the overlying aggregate is compacted, the effect is to provide an efficient means by which to transfer dynamic loads to the RockGrid and thereby form a composite material with increased stiffness and better performance when trafficked.
