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.

This app provides general UK guidance and material estimates only. It is not legal, planning, engineering or building-control advice. Always confirm requirements with your local planning authority, building control, utility providers, manufacturers or qualified professionals.
