MZ-438 is a 38 mm HDPE grass reinforcement grid for pedestrian areas, footpaths and landscape verges. Although the legacy title referred to a driveway paver, the original application table lists pedestrian areas, verges and footpaths; this updated positioning follows those confirmed uses.
The interconnected cells support soil and grass while helping protect the root zone from direct surface wear. Pavement performance depends on the prepared subgrade, drainage, base materials, edge restraint, fill and expected traffic.

Application Focus
- Pedestrian grass paths
- Landscape verges and green margins
- Garden footpaths
- Low-intensity access areas where a grass finish is required
For regular vehicle routes or heavy parking, select a model and pavement build-up specifically engineered for those loads. The product strength value should not be treated as a substitute for site-specific pavement design.
Installation Guidance
- Excavate and compact the formation to the design level.
- Install separation geotextile and the specified permeable sub-base.
- Prepare a level bedding layer and provide edge restraints.
- Connect the grids and cut neatly at boundaries.
- Fill cells with suitable growing medium, then seed or turf.
- Allow vegetation to establish before opening the area to use.
