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 Keynsham we check levels against door thresholds, look for shallow services and plan where spoil and materials will go. Around Keynsham, longer drives and rural access are common, so deliveries and mixing space are planned at survey.
Typical projects we can quote for in Keynsham include adding a soakaway so water stays on the property, digging out an old drive and building a permeable sub-base and replacing failed edges that have started to crumble. More about excavation and sub-base.

Planning in Keynsham
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 England, not legal advice.
Weather and working days
The South West gets more rain than the east of England, especially on higher ground, so permeability and falls matter on every drive. We only lay resin on dry days with ground and air above about 5°C, so Keynsham jobs are booked with the forecast in mind.
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.
Excavation and sub-base in Keynsham: questions
Who approves dropped kerbs in Keynsham?
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.
Do I need planning permission in Keynsham?
In England, a new or replaced hard surface of more than 5 m² in a front garden is permitted development only if it is porous, or if rainwater drains to a lawn, border or soakaway within the property. A fully permeable resin bound build, with a porous base under it, meets that test.
Is the price fixed for Keynsham jobs?
Yes, once the scope and specification are agreed in writing. If hidden ground conditions turn up, we explain and agree any change with you before doing extra work.
