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 Barnet we check levels against door thresholds, look for shallow services and plan where spoil and materials will go. Homes in Barnet range from period properties to modern estates, each with its own drainage and access questions.
Typical projects we can quote for in Barnet include digging out an old drive and building a permeable sub-base, preparing a drive to meet a new dropped kerb and replacing failed edges that have started to crumble. More about excavation and sub-base.

Planning in Barnet
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
London is one of the drier parts of the UK, but heavy summer downpours on small, mostly paved plots are exactly what front-garden drainage rules were written for. Laying days in Barnet are confirmed close to the date, because rain and cold stop resin curing properly.

Excavation and sub-base in Barnet: questions
Who approves dropped kerbs in Barnet?
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.
Is the price fixed for Barnet 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.
Do I need planning permission in Barnet?
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.
