Those persistent puddles in your Colliers Wood garden aren't going anywhere without proper drainage. Clay soil meets London rain here in SW19, creating waterlogging challenges that French drains solve brilliantly.
Response within 24 hours
Victorian terraces and post-war semis throughout Colliers Wood share a common enemy: poor drainage. Heavy clay beneath most SW19 properties traps water like a bathtub, turning lawns into swamps after every downpour. French drains channel this excess water away through gravel-filled trenches, protecting foundations and rescuing sodden gardens. Local homeowners increasingly recognise these systems as the permanent fix their waterlogged plots need.
Installation begins with identifying water flow patterns unique to each property's gradient and soil composition. Perforated pipes laid in gravel-packed channels intercept groundwater before it surfaces. The system directs collected water towards soakaways or storm drains, depending on local regulations and site conditions. Depth varies between 450mm and 900mm, ensuring effectiveness without disrupting existing landscaping unnecessarily.
Twenty years solving drainage problems across South London means understanding exactly how Colliers Wood's terrain behaves. Every installation considers neighbouring properties and shared boundaries common in SW19's tightly-packed streets.
