ECCOdal grass grids are made from HDPE (High-Density Polyethylene), this allows them to remain flexible, even in freezing temperatures, and they will therefore not break. In addition, ECCOdal grass grids have expansion joints to deal with temperature differences, so the grass grids will not shift against each other. Moreover, ECCOdal grass grids are also suited for cars, thus the ideal surface for an (additional) parking area or driveway.
Lastly, ECCOdal grass grids were specifically designed as grass grids, unlike other sheets that can be used both as gravel sheets and as grass grids.
The technical specifications for ECCOdal grass grids are specifically aimed at grass filling, while ECCOdal gravel sheets are specifically aimed at a gravel filling.
