The minimum amount of cover you can have on top of a tank is 250 millimeters, suitable for pedestrian-only access without any vehicle loading. The maximum amount of cover depends on the type of crates used. Light-duty crates require less cover, while heavy-duty crates can accommodate greater loads. The maximum recommended cover above the tank is 2.75 metres. For specific projects, site-specific calculations can be done to determine the optimal amount of cover based on loading requirements. The information regarding minimum and maximum cover will be provided in the spec sheets or can be obtained through site-specific calculations based on the drainage drawing.
