Those Victorian terraces around Crystal Palace weren't built with modern drainage demands in mind. Whether your Anerley property suffers from waterlogged lawns or your Upper Norwood driveway floods every winter, a professionally installed soakaway could transform how your land manages surface water.

Crystal Palace's hillside location presents unique drainage challenges that local homeowners know all too well. Heavy clay soil combined with sloping gardens means rainwater often has nowhere to go, particularly in those characterful properties dotting Church Road and Westow Hill. Modern soakaway systems work brilliantly here, creating underground chambers that collect and gradually disperse excess water rather than letting it pool on your patio or saturate your foundations.
Installation involves excavating to the correct depth based on your specific ground conditions and water table levels. Percolation tests determine exactly how your soil handles water dispersal - crucial given SE19's varied geology from London clay to patches of gravel. The chamber gets wrapped in geotextile membrane, filled with clean aggregate, then connected to your existing drainage via perforated pipes positioned at precise gradients.
Twenty years solving drainage puzzles across Penge and beyond means recognising each property's quirks before the digger arrives. Local building control officers appreciate thorough applications backed by proper calculations, something many contractors overlook.
Rated 4.9/5 from over 280 verified reviews
Most residential soakaways in SE20 range between £1,800-£3,500, influenced heavily by access difficulties common to period properties and the depth required to hit suitable ground conditions. Larger systems serving multiple downpipes or extensive driveways naturally sit higher.
Absolutely - from the conservation area properties near the park to modern developments in Anerley, throughout SE19 and SE20. Regular work extends to neighbouring Penge, Sydenham borders and up towards Norwood Junction.
Typical domestic installations complete within 2-3 days, weather permitting. Complex sites with restricted access or multiple chambers might stretch to 4-5 days including reinstatement work.
Each soakaway installation includes decade-long coverage against defects in workmanship or materials. This warranty transfers with property ownership and covers the complete system from inlet pipes to the soakaway chamber itself.
Combined systems work excellently for multiple water sources. Calculations factor in your total catchment area - roofs, patios, driveways - ensuring adequate capacity even during those intense summer storms Crystal Palace occasionally experiences.
