The results from this aggregate quantity calculator should only be used a rough guide as exact conversions will depend on a number of factors that are beyond Longcliffe's control. These vary from moisture contents and method/degree of compaction to type of sub-base in use etc. Longcliffe cannot be held contractually responsible for any surplus or shortfall found on site. If in doubt speak to your Longcliffe representative who can advise on individual requirements.
