To Calculate how much material you require for a given area, you will need to know the loose bulk density (LBD) of the material.
Sand – LBD = 1.6t/m³
Grit – LBD = 1.6t/m³
Soil – LBD =1.7t/m³
Gravel – LBD =1.8t/m³
Our Rootzone – LBD = 1.45t/m³
Sand Soil Rootzone – LBD =1.7t/m³
500m² ECO RootZone @ 300mm firmed depth.
500 x 0.330 = 165m³
ECO RootZone = 239 tonnes
500m², standard sand soil rootzone = 280 tonnes
41 tonnes MORE!
