Foundations in Maidstone
Foundations are the below-ground concrete structure that transfers the load of a building safely into the ground, with the type — strip, trench-fill or raft — and depth determined by ground conditions, nearby trees and the load of the structure above.
In Maidstone, that covers Allington, Barming, Loose, Penenden Heath, Tovil, Weavering, Bearsted. Maidstone is the county town of Kent, set on the River Medway, with a historic centre and a broad mix of Victorian terraces, interwar suburbs and newer estate development across the wider town and surrounding villages.

FAQs
Foundations in Maidstone: FAQs
Do you provide foundations across all of Maidstone?
Yes, we cover the ME14, ME15 and ME16 postcode areas in full, including Allington, Barming, Loose, Penenden Heath, Tovil, Weavering, Bearsted.
How deep do foundations need to be?
Depth depends on ground conditions, the load of the structure and proximity to trees or drains — a straightforward strip foundation might be around 1m deep, but clay soils near mature trees can require significantly deeper trench-fill foundations. This is confirmed by site investigation and agreed with Building Control.
Does Building Control need to inspect the foundations before concrete is poured?
Yes. An open-trench inspection is a standard Building Control stage, carried out once excavation is complete and before concrete is poured, to confirm the ground conditions and depth match what was approved.
Does flood risk from the River Medway affect extensions in Maidstone?
For properties in flood risk areas, extension design may need to take flood resilience into account, and a flood risk assessment can be required as part of a planning application. We check the Environment Agency flood mapping for your property during feasibility.
