Clay soil expansion across SM4 creates unique challenges for local properties. Those charming Edwardian homes near Morden Park often need underpinning, whilst newer builds require carefully engineered foundations to prevent seasonal movement. Understanding Morden's geological quirks means designing foundations that actually work, not just meet minimum standards.
Strip foundations suit most Morden properties, reaching below the active clay layer at around 1.2 metres. Reinforced concrete poured into precisely excavated trenches creates a stable base, engineered to handle both the building load and ground pressure. Modern waterproofing membranes prevent moisture penetration - crucial given South London's high water table.
Twenty years digging through Morden's tricky ground conditions teaches you which corners matter. Local building control know our work meets their standards first time, saving weeks on approvals.

Basic strip foundations for a single-storey extension start around £8,000-£12,000. Full house foundations typically range £15,000-£25,000, depending on ground conditions and building footprint.
Absolutely - from St Helier's estate renovations to Lower Morden's new developments. Regular projects include Morden Hall Park's boundary properties where tree roots complicate excavations.
Standard domestic foundations take 2-3 weeks including excavation, steel fixing and concrete curing. Complex underpinning projects might stretch to 4-6 weeks.
Each project includes decade-long structural warranty covering settlement, cracking or water ingress. Insurance-backed certification provides genuine peace of mind.
Underpinning extends foundations deeper without demolition. Mini-piles or mass concrete techniques stabilise subsiding properties - particularly effective for Morden's older housing stock experiencing movement.
