No setting of crushed rock by hand is necessary. The mesh that holds the rock is made from hot dipped galvanized steel, and can easily be filled with small sized crushed rock.
The mesh has a material strength of 0.19 - 0.23 inches or 6/5/6mm, with mesh size 25/200 mm. With little compacting, it’s easy for the rocks to settle in a solid positon when the GridWall is being filled.
With its slim width of just under 4 inches (10 cm) GridWall+ is the slimmest in the market today.
