Those grand Victorian properties throughout Dulwich didn't last 150 years by chance - their foundations were built to endure London's notorious clay. Today's foundations demand the same meticulous approach, whether you're extending a period home in Village Way or breaking ground on Lordship Lane.

South London's clay soil shifts like nowhere else, particularly here where Dulwich sits between Crystal Palace's heights and Camberwell's lower ground. Every foundation poured needs to account for seasonal movement that can crack lesser work within months. Local knowledge matters when your property's stability hangs in the balance.
Reinforced concrete strips, engineered pile systems, or traditional mass concrete - the right choice depends entirely on your plot's specifics. Ground surveys reveal moisture patterns unique to each street, from waterlogged gardens near Dulwich Park to the drier plots backing onto Sydenham Hill Woods. Steel reinforcement placement follows calculations based on actual soil samples, not generic specifications.
