Excavation and sub-base across Gwynedd
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.
In Bangor we can price work such as preparing a drive to meet a new dropped kerb, digging out an old drive and building a permeable sub-base and adding a soakaway so water stays on the property.

Planning in Gwynedd
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
North Wales ranges from mild coastal towns to wetter upland areas, so drainage and laying days are planned with the weather in mind. Spring to autumn offers the most laying days in Gwynedd, but dry, mild winter days can work too.

Excavation and sub-base in Gwynedd: questions
Do I need planning permission in Gwynedd?
Wales has its own permitted development rules on the same principle: a front-garden hard surface should be porous or drain to a permeable area on the property. A fully permeable resin bound build, with a porous base under it, meets that test.
Who approves dropped kerbs in Gwynedd?
Dropped kerb consent comes from your council as local highway authority. We help with the application and get your drive ready to meet the new crossing.
What postcodes do you cover around Gwynedd?
We cover LL and the surrounding districts, including Bangor and Llandudno.
