Foundations on Surrey soils
The right foundation depends on the ground. Clay, common around parts of Guildford and in the Weald towards Cranleigh, swells in winter and shrinks in summer, especially near trees, so foundations often need to go deeper. Chalk and sandy greensand are more stable but still need to reach firm, undisturbed ground. We dig to the depth required by your engineer or Building Control and arrange inspections before concrete is poured.
Accurate setting out
Our team sets out foundations accurately from your drawings, so walls end up exactly where they should. We can provide a digger and driver for fast, tidy excavation in restricted gardens, and handle the drainage runs around the new build at the same time.
We work across Guildford, Godalming, Woking and Cranleigh, plus the villages in between.
Frequently asked questions
How deep do extension foundations need to be?
Typically at least 1 metre, deeper on clay soils and near trees. The exact depth is set by your structural engineer or Building Control officer after looking at the ground.
Do foundations need to be inspected?
Yes. For work under Building Regulations, the excavated trenches are inspected by Building Control before concrete is poured. We work around those inspections.
How long does foundation work take?
Foundations for a typical single-storey extension usually take a few days, depending on size, access and inspection timings.
