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 Welwyn Garden City we check levels against door thresholds, look for shallow services and plan where spoil and materials will go. Many homes in Welwyn Garden City have existing tarmac or block drives that can be assessed for an overlay or a rebuild.
Projects we quote in and around Welwyn Garden City include digging out an old drive and building a permeable sub-base, setting a channel drain across a garage entrance and adding a soakaway so water stays on the property. More about excavation and sub-base.

Planning in Welwyn Garden City
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 East of England is the driest part of the UK, which gives a long resin laying season, though heavy clays in places mean the sub-base needs designing for slow drainage. Surveys run all year; resin work itself waits for a dry day above about 5°C.

Excavation and sub-base in Welwyn Garden City: questions
Is the price fixed for Welwyn Garden City 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 Welwyn Garden City?
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 Welwyn Garden City?
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.
