Those challenging slopes around Sanderstead require foundations that understand the terrain. From Victorian terrace underpinning to new build groundworks on Hamsey Green's clay soils, proper footings make the difference between a lifetime's stability and costly remedial work.

Sanderstead's mix of period properties and modern developments sits on surprisingly varied ground conditions. Clay deposits shift between Purley Oaks and the ridge towards South Croydon, while pockets of chalk create their own challenges. Understanding these local variations transforms foundation work from guesswork into precision engineering.
Strip foundations suit many of CR2's standard plots, but stepped footings become essential where gardens slope towards the valley. Reinforced concrete rafts handle the heavier clay movement near Hamsey Green's lower streets. Each foundation type demands specific steel placement, concrete mix ratios, and waterproofing strategies tailored to actual ground conditions rather than textbook assumptions.
Twenty years digging through Sanderstead's geology builds invaluable local knowledge. Every notable ground movement pattern, every drainage quirk affecting nearby streets - this accumulated wisdom prevents expensive surprises during your build.
Rated 4.9/5 from over 280 verified reviews
Standard house footings typically range £8,000-£15,000, though underpinning Victorian properties often reaches £20,000-£35,000. Site access and ground conditions significantly affect costs.
Absolutely - from the elevated plots near Riddlesdown to the flatter sections around Purley Oaks station, we work across all of CR2's diverse terrain.
Most residential footings take 2-3 weeks including excavation and curing time. Complex underpinning projects typically need 4-6 weeks.
All structural foundation work carries our comprehensive 10-year warranty, backed by professional indemnity insurance and regular inspection certificates.
Load calculations determine whether existing footings need reinforcement. Many 1930s Sanderstead homes have surprisingly robust foundations, but structural surveys reveal the true capacity.
