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.
In Carshalton, the survey for this work is about levels, falls and ground conditions: where water goes now, what is under the surface and how materials will reach the site. Carshalton mixes older streets with newer estates, and many homes have room for two or more cars.
Typical projects we can quote for in Carshalton include digging out an old drive and building a permeable sub-base, setting a channel drain across a garage entrance and replacing failed edges that have started to crumble. More about excavation and sub-base.

Planning in Carshalton
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. If the weather turns on the day, we move the pour rather than risk a surface that will not cure.

Excavation and sub-base in Carshalton: questions
Do I need planning permission in Carshalton?
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.
Who approves dropped kerbs in Carshalton?
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 Carshalton 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.
