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 Risca we check levels against door thresholds, look for shallow services and plan where spoil and materials will go. In and around Risca, drives often run further from the road, so edging, falls and drainage are planned along the whole length.
Projects we quote in and around Risca include fitting setts or steel edging around a new drive, preparing a drive to meet a new dropped kerb and adding a soakaway so water stays on the property. More about excavation and sub-base.
Prices for excavation and sub-base in Risca

Planning in Risca
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. Surveys run all year; resin work itself waits for a dry day above about 5°C.
How it works
Guide price first, then a free visit, then a line-by-line quote. Nothing is booked until you have the specification in writing.
