Those heavy clay slopes around Sanderstead create unique drainage headaches that most gardeners simply aren't equipped to handle. Years of watching water pool against Victorian foundations has taught us exactly where problems hide in CR2's distinctive terrain.
Response within 24 hours
Clay-heavy gardens throughout Sanderstead struggle with water retention, particularly where older properties meet modern extensions. Victorian and Edwardian homes near Limpsfield Road often face waterlogging issues that weren't apparent when these houses were first built. The combination of mature tree roots, compacted soil, and changing weather patterns means drainage problems have become increasingly common across CR2.
Modern drainage systems require careful integration with existing soakaways and natural water courses that flow through Sanderstead's hillside plots. French drains positioned strategically along property boundaries can redirect surface water away from vulnerable foundations. Permeable surfaces work particularly well with the local geology, allowing controlled absorption whilst preventing the clay from becoming oversaturated during prolonged rainfall.
Twenty years tackling Sanderstead's notorious clay has given us insights no textbook teaches. Local knowledge matters when you're dealing with springs that only appear after heavy rain, or understanding how Hamsey Green's higher elevation affects water flow patterns down towards Purley Oaks.
