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 Harpenden, 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. Harpenden mixes older streets with newer estates, and many homes have room for two or more cars.
Projects we quote in and around Harpenden include preparing a drive to meet a new dropped kerb, digging out an old drive and building a permeable sub-base and setting a channel drain across a garage entrance. More about excavation and sub-base.

Planning in Harpenden
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. We only lay resin on dry days with ground and air above about 5°C, so Harpenden jobs are booked with the forecast in mind.

Excavation and sub-base in Harpenden: questions
Do I need planning permission in Harpenden?
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 Harpenden 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.
