Excavation and sub-base across Gwent
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.
Depth depends on the ground and the load. Clay, made ground and old garden soil need more depth than firm gravelly ground. Where services such as water pipes or cables run shallow, they are located before digging.
Across Gwent, the projects we price include setting a channel drain across a garage entrance, fitting setts or steel edging around a new drive and digging out an old drive and building a permeable sub-base.
Prices in Gwent
Labour and material costs in South Wales run below the UK average, and the guide figures below reflect that. They include VAT and are confirmed after a survey.

Planning in Gwent
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
South Wales is wetter than most of England, so a permeable build or a planned route for water is essential on every drive. If the weather turns on the day, we move the pour rather than risk a surface that will not cure.
