20mm: Perfect for concrete, drainage and septic tank trenches.
10mm: Highly and most suitably used in driveways, pathways, as inorganic mulch in gardens, pots and planter boxes.
5mm: Is a natural product used for back-filling trenches, around PVC and Ag-Pipe, and for drainage behind retaining walls.
