Heavy Duty Ground Grid (HDGG)

The HDGG is a high quality, extra heavy duty porous paving system manufactured from 100% recycled plastic (hanit®). It is simple to install, SuDs compliant and designed for extreme loads such as truck parks, lay-bys and loading areas. The interconnecting 60cm x 40cm x 8cm deep units are fast to install due to their light unit weight (9kg) and are very tolerant of site handling damage. Installed on a grit bedding over a free draining type 3 sub base they can be filled with a grass or gravel finish to enhance the surrounding environment whilst still enabling regular overrun by coaches, busses, HGV’s or forklifts.
