Water pooling in your Norbury garden after every downpour? Those Victorian clay soils around SW16 don't drain themselves, and surface water can wreak havoc on foundations built over a century ago.
Response within 24 hours
Norbury's mix of Edwardian semis and post-war developments face unique drainage challenges. Clay-heavy soil, combined with the area's natural slope towards the River Graveney, creates persistent waterlogging issues. Properties near Norbury Park often struggle with runoff, while homes closer to Thornton Heath's retail corridor battle compacted earth from decades of urban development. A properly installed French drain system redirects excess water away from vulnerable spots.
Installation begins with precise gradient calculations specific to your property's topography. Perforated pipes wrapped in geotextile fabric prevent soil infiltration whilst maintaining water flow. Gravel aggregates sized between 20-40mm create optimal drainage channels. The entire system connects to existing soakaways or storm drains, complying with Thames Water regulations for the CR7 catchment area.
Twenty years tackling South London's drainage puzzles means understanding every quirk of Norbury's terrain. From Pollards Hill's elevated plots to Streatham Common's border properties, each installation reflects intimate knowledge of local conditions.
