CR5's chalky soil and hillside terrain create unique challenges for homeowners. Whether you're extending that 1930s semi or sorting waterlogged gardens near Farthing Downs, groundworks form the backbone of any successful project. Years of working these Surrey hills have taught us exactly where water flows and how foundations behave on Coulsdon's distinctive landscape.
Excavation depth varies dramatically across the area - shallow chalk near Kenley aerodrome versus deeper clay deposits around Old Coulsdon. Modern groundworks incorporate sustainable drainage systems, crucial when your property sits above the underground streams feeding the Bourne. Proper compaction, correct aggregate selection, and understanding local water tables prevent those costly surprises months down the line.
Local knowledge beats generic solutions every time. That's why Purley homeowners and Chipstead residents regularly recommend our work - they've seen the difference proper groundworks make on these challenging plots.
