Those steep Putney gardens and clay-heavy soil beneath Victorian properties demand proper foundations. Getting the groundwork right means your new structure stays level for decades, not seasons.

Putney's mix of period homes and newer builds each bring unique challenges for base installation. Victorian terraces often hide old coal bunkers and forgotten drainage runs that need careful navigation. Meanwhile, properties backing onto Richmond Park face strict planning considerations for any permanent structures. Local knowledge matters when you're digging foundations in SW15.
A properly engineered base starts with excavation to below the frost line - crucial given how London clay expands and contracts. Steel mesh reinforcement gets positioned precisely before pouring, creating a monolithic slab that resists cracking. The concrete mix itself needs adjusting based on ground conditions; what works near the Thames towpath won't suit the higher ground around Putney Heath. Final finishing determines whether water pools or drains away effectively.
Twenty years of working between Putney Bridge and Roehampton means knowing which properties sit on old gravel beds versus heavy clay. Every project gets the same meticulous approach, whether it's a compact bike store for a flat conversion or a double garage for those fortunate enough to have off-street parking.

Standard shed bases (8x6ft) start around £650-800, while double garage foundations typically range £2,200-3,500. Properties with difficult access or sloping gardens may incur additional groundwork costs.
Absolutely - from the riverside properties near Putney Embankment to homes bordering Richmond Park. Regular projects across Putney Heath, West Hill and the Roehampton area too.
Smaller bases often complete within 2-3 days including excavation and curing time. Larger garage foundations typically need 4-5 days, weather permitting.
Each base carries decade-long protection against structural failure. This covers any cracking, subsidence or deterioration arising from workmanship - giving genuine peace of mind for your investment.
Narrow Victorian side returns are common in Putney - we use compact machinery and wheelbarrow concrete where needed. Even properties with access only through the house can be accommodated with proper planning and protection.
