Those persistent puddles after rain in Thornton Heath gardens? Clay soil meets Victorian-era drainage equals water havoc. Let's sort that properly with a French drain system designed for CR7's unique ground conditions.
Response within 24 hours
Thornton Heath sits on London clay that's notorious for poor drainage. Walk down any street between the station and Brigstock Road after heavy rain - you'll spot the telltale signs. Waterlogged lawns, flooded patios, even water pooling against house foundations. French drains tackle this head-on by creating underground channels that guide excess water away from where it causes damage.
Installation begins with precise gradient calculations specific to your property's layout. Perforated pipes wrapped in geotextile membrane prevent soil infiltration whilst maintaining water flow. Gravel backfill creates additional drainage capacity. Strategic positioning ensures water diverts from vulnerable areas - particularly important given how many CR7 properties have extensions built into sloping gardens.
Twenty years working across South London means understanding each area's quirks. Thornton Heath's mix of Edwardian terraces and post-war developments each present distinct drainage puzzles.
