Those heavy clay soils around Orpington don't drain themselves. Whether you're battling waterlogged lawns near Goddington Park or pooling driveways in Chelsfield, properly designed soakaways transform problem plots into dry, useable spaces.
Response within 24 hours
Clay-heavy gardens throughout BR5 and BR6 present unique drainage challenges, particularly in older properties where original Victorian soakaways have long since collapsed. Modern crate systems work brilliantly here, handling the runoff from both traditional slate roofs and contemporary extensions. Each installation starts with percolation testing – crucial given how dramatically soil conditions vary between Petts Wood's sandier patches and St Mary Cray's notorious clay belt.
Today's soakaway technology far exceeds old rubble pits. Modular crates wrapped in geotextile membrane create void spaces that handle serious water volumes whilst preventing silt ingress. Calculations factor in your roof area, driveway size, and local rainfall data specific to this part of Kent. The difference shows immediately – no more squelchy lawns after thunderstorms, no driveway lakes when autumn arrives.
Twenty-plus years working Orpington's varied geology means knowing exactly where traditional soakaways fail and where innovative solutions excel. Local building control officers know our installations meet every requirement first time.




Rated 4.9/5 from over 280 verified reviews
Most domestic soakaways in BR5/BR6 range from £1,800-£3,500, depending on capacity requirements and access constraints. Larger properties near Chelsfield Village with extensive roof areas might reach £5,000.
Absolutely – from Locksbottom to Green Street Green, covering all BR5 and BR6 postcodes. Regular projects in Petts Wood, Chelsfield, and St Mary Cray too.
Standard residential soakaways usually complete within 2-3 days, weather permitting. Complex multi-crate systems serving large properties might extend to 4-5 days.
Every soakaway carries our decade-long warranty covering both materials and workmanship. This includes the crate system, pipework, and all connections – genuine peace of mind for Orpington homeowners.
Clay presents challenges but isn't insurmountable. Where percolation tests show poor drainage, we design larger systems or combine soakaways with alternative solutions like rain gardens or attenuation tanks.
