Those persistent puddles on your Balham driveway aren't just annoying – they're washing valuable topsoil into already-strained SW12 storm drains. Permeable paving lets rain soak through naturally, keeping your property dry whilst helping the local water table.

Victorian terraces throughout Balham face unique drainage challenges, particularly where original clay soil meets modern hard landscaping. Between Nightingale Lane and Bedford Hill, countless properties struggle with surface water that has nowhere to go. Permeable surfaces solve this elegantly, channelling rainfall straight down through specially-designed gaps into sub-base reservoirs.
Installation begins with excavating to approximately 350mm depth, laying angular aggregate that creates void spaces for water storage. Geotextile membrane prevents soil migration whilst maintaining porosity. The blocks themselves – whether concrete, clay or natural stone – interlock with wider joints than traditional paving, filled with fine gravel that filters runoff. This system manages up to 6,000mm of rainfall annually, far exceeding London's average.
Balham homeowners trust our decade-long presence in SW12, where we've transformed everything from compact courtyard gardens to sweeping gravel drives near Wandsworth Common. Local planning officers regularly recommend our SUDS-compliant designs.

Typical Balham driveways (40-60m²) range £4,500-£8,000 including excavation and drainage layers. Larger properties near Tooting Bec Common averaging 80-100m² usually fall between £9,000-£13,000, depending on block choice and existing ground conditions.
Absolutely – our teams work across SW12 daily, from Nightingale Triangle properties to homes backing onto Tooting Bec Common. We also cover neighbouring Clapham South, Streatham Hill and Wandsworth Common areas.
Most Balham driveways require 5-7 working days from excavation through to completion. Larger installations or those requiring additional drainage connections typically extend to 8-10 days.
Every permeable installation carries our decade-long structural warranty covering both surface integrity and drainage performance. This includes annual inspections for the first two years, ensuring proper percolation rates are maintained.
Gradients up to 1:10 work brilliantly with permeable systems – we simply adjust sub-base depths and incorporate check dams where needed. Many hillside properties between Ramsden Road and Elmfield Road benefit from this approach, preventing the rushing water that previously overwhelmed conventional drains.
