Those Victorian terraces along Woodcote Road need solid groundwork just as much as the newer builds near Roundshaw. Whether you're extending sideways or adding a garden studio, the right foundation determines everything that follows.

Wallington's mix of chalk and London clay presents interesting challenges beneath the surface. Properties near Manor Road often sit on different soil conditions than those closer to Beddington Park. Understanding these variations shapes how deep we dig and what reinforcement methods suit each plot. Local building control officers know these quirks well, and so do we.
Modern foundation work involves more than pouring concrete into trenches. Ground-penetrating radar identifies old wells and soakaways common in SM6's older districts. Steel reinforcement gets calculated based on load requirements and soil reports. Waterproof membranes protect against the area's seasonal water table fluctuations, particularly crucial for basements near the Wandle tributaries.
Twenty-three years working between Carshalton ponds and Purley Way builds specific knowledge. Each project teaches something new about local ground conditions, from unexpected Victorian footings to natural springs.

Strip foundations for a single-storey extension usually range £4,000-£7,000. Raft foundations for challenging ground conditions might reach £12,000-£18,000. Site access and soil type significantly influence final costs.
Yes, from Mellows Park across to Bandon Hill, including all of central Wallington. Regular projects span from The Grange through to properties backing onto Beddington Park.
Standard domestic footings typically take 8-12 working days including excavation, concrete pour, and curing time. Complex ground conditions or larger footprints may extend this to 3-4 weeks.
All structural groundwork carries decade-long coverage against settlement or failure. This includes materials, workmanship, and any remedial work needed within ten years of completion.
Often requires underpinning or reinforcement, especially in pre-1960s Wallington homes. A structural engineer's assessment determines whether existing footings can handle increased loads or need strengthening work.
