Excavation and sub-base across Cornwall
Excavation and sub-base work is the groundwork under a resin surface: digging out the old drive and soft ground, removing the spoil, and building up compacted layers of crushed stone and a binder course that will carry cars without moving.
Base preparation is commonly 30–45% of a new resin drive budget, and it is where corners get cut. A thin base, unwashed fines in a permeable build, or poor compaction show up as cracks and dips within a few winters.
Projects we quote in and around Redruth include adding a soakaway so water stays on the property, replacing failed edges that have started to crumble and preparing a drive to meet a new dropped kerb.
Prices in Cornwall
Labour and material costs in the South West run above the UK average, and the guide figures below reflect that. They include VAT and are confirmed after a survey.

Planning in Cornwall
Groundworks for a domestic drive do not usually need planning permission in themselves, but the finished surface follows the front-garden drainage rules, and shallow services such as water pipes and cables are located before digging.
Weather and working days
The South West gets more rain than the east of England, especially on higher ground, so permeability and falls matter on every drive. We only lay resin on dry days with ground and air above about 5°C, so Redruth jobs are booked with the forecast in mind.
