What excavation and sub-base involves
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.
Before quoting groundworks in Blackwood we check levels against door thresholds, look for shallow services and plan where spoil and materials will go. Around Blackwood, longer drives and rural access are common, so deliveries and mixing space are planned at survey.
Across Gwent, the projects we price include digging out an old drive and building a permeable sub-base, adding a soakaway so water stays on the property and setting a channel drain across a garage entrance. More about excavation and sub-base.

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.
General information for Wales, not legal advice.
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.
How it works
The steps are simple: guide price, free survey, written quote with a fixed price once the specification is agreed, then a date that suits you and the weather.
