Those Victorian terraces in Shortlands weren't built with modern drainage in mind. Clay soil, sloping gardens, and unpredictable British weather create the perfect storm for waterlogged lawns and damp basements throughout Bromley.

Heavy clay beneath most Bromley properties means rainwater sits rather than soaks. Gardens flood, patios puddle, and those characterful period foundations start showing signs of moisture damage. French drains redirect this stubborn surface water away from vulnerable areas, channelling it safely through gravel-filled trenches to proper drainage points.
Installation begins with precise gradient calculations - even a 1% slope makes all the difference. Perforated pipes wrapped in geotextile fabric prevent soil clogging whilst allowing water entry. The surrounding aggregate creates a permeable channel that captures runoff across its entire length. Positioned strategically around patios, along retaining walls, or across boggy lawn sections, these systems transform problem areas into usable space year-round.
Twenty years solving drainage puzzles across Bromley's varied terrain brings invaluable local knowledge. From Bickley's spacious Edwardian plots to Sundridge's compact modern developments, each property presents unique challenges that template solutions simply can't address.

Most residential projects in BR1-BR3 range from £85-120 per metre, depending on depth requirements and access constraints. A standard 20-metre system protecting a patio area usually falls between £1,700-2,400 inclusive.
Absolutely - from the town centre's BR1 postcode through to leafy BR2 and residential BR3. Regular projects in Shortlands, Bickley and Sundridge mean we know the local soil conditions intimately.
Typical garden drainage systems take 2-4 days from excavation to completion. Immediate improvement follows installation, though full effectiveness develops as water finds its new pathways over subsequent rainfall.
Every system carries decade-long protection against defects. This covers pipe integrity, gradient accuracy, and drainage performance - essentially ensuring your investment keeps working as promised through ten years of Bromley weather.
Interceptor drains positioned upslope from foundations dramatically reduce hydrostatic pressure against basement walls. Combined with proper surface grading, they're often the most effective solution for period properties suffering persistent damp issues.
