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 Isleworth we check levels against door thresholds, look for shallow services and plan where spoil and materials will go. Isleworth mixes older streets with newer estates, and many homes have room for two or more cars.
Across Greater London, the projects we price include digging out an old drive and building a permeable sub-base, preparing a drive to meet a new dropped kerb and setting a channel drain across a garage entrance. More about excavation and sub-base.

Planning in Isleworth
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. Surveys run all year; resin work itself waits for a dry day above about 5°C.

Excavation and sub-base in Isleworth: questions
What postcodes do you cover around Isleworth?
We cover TW7, TW3 and TW5 and the surrounding districts, including Hounslow and Heston.
Do I need planning permission in Isleworth?
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 Isleworth 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.
