Excavation and sub-base across South Glamorgan
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 Cardiff include preparing a drive to meet a new dropped kerb, setting a channel drain across a garage entrance and replacing failed edges that have started to crumble.

Planning in South Glamorgan
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. Laying days in Cardiff are confirmed close to the date, because rain and cold stop resin curing properly.
