Foundations in Redhill
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 Redhill, that covers Earlswood, Salfords, South Park, Whitebushes, St John's, Three Arch Road. Redhill developed rapidly as a Victorian railway town and today has a mixed housing stock including Victorian terraces close to the centre, interwar suburbs, and later estate housing further out, with good rail links into London.

FAQs
Foundations in Redhill: FAQs
Do you provide foundations across all of Redhill?
Yes, we cover the RH1 postcode area in full, including Earlswood, Salfords, South Park, Whitebushes, St John's, Three Arch Road.
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.
Are Redhill's Victorian terraces suitable for loft conversions?
Many are, subject to roof pitch and head height, which we assess on survey. Rear dormers are a common solution to gain additional headroom on this house type.
