Persistent puddles after rain? Those waterlogged patches near Mitcham Common's clay-heavy areas need proper drainage solutions. Local knowledge makes all the difference when tackling South London's unpredictable water table.

Mitcham's mix of Victorian properties and 1960s developments creates unique drainage challenges. Clay soil dominates the area between Figges Marsh and Colliers Wood, meaning surface water has nowhere to go without proper intervention. Years of extensions and patio installations have often blocked natural drainage paths, leaving gardens resembling temporary ponds whenever storms hit.
Modern soakaway systems use perforated crates buried beneath your garden, creating underground reservoirs that gradually release water into surrounding soil. Calculating the right capacity involves measuring your roof area, hard surfaces, and local rainfall data - particularly important given Mitcham's tendency for sudden downpours. Percolation tests determine how quickly your specific patch of ground absorbs water, ensuring the system won't overwhelm during heavy rain.
Having installed drainage across hundreds of Mitcham properties, from compact terraces near the tram stops to sprawling gardens backing onto the Common, understanding local ground conditions proves invaluable. Each street presents different challenges - what works perfectly on the sandier patches near Pollards Hill might fail completely in the dense clay around Eastfields.
