Frequently asked questions
- How much MOT Type 1 sub-base do I need?
- Multiply your area in m² by the compacted depth in metres (100 mm for patios, 150 mm for driveways), add about 25% for compaction, then roughly 2.1 tonnes per m³. The MOT Type 1 calculator works this out in tonnes and bulk bags for you.
- Are the Garden Surveyor calculators free?
- Yes — every UK landscaping calculator (paving, sub-base, gravel, turf, fencing, decking and artificial grass) is free to use, with no sign-up needed for an estimate.
- Are the estimates accurate for UK jobs?
- The calculators use UK build-up depths, coverage rates and compaction factors, and add cutting and waste allowances. They give a reliable material take-off to quote from, but always confirm against your supplier and site conditions.
