Those narrow side returns and basement conversions so popular in SW18 often trap water against foundations, while paved front gardens struggle with runoff during heavy rain. Clay beneath Wandsworth's topsoil compounds these issues, preventing natural drainage. Smart channel systems and permeable surfaces work together to guide water away from your property, whether you're dealing with a sloped Earlsfield garden or a flat Battersea courtyard.
Modern drainage combines discrete channels with soakaways positioned where they'll actually function in London clay. ACO drains blend seamlessly into block paving, while French drains hidden beneath decorative gravel handle overflow. Calculating correct gradients ensures water flows away from Victorian bay windows and basement light wells. Strategic placement prevents pooling where kids play or cars park daily.
Twenty years installing drainage across SW18 reveals patterns – which streets flood first, where clay's thickest, how local topography affects each property. This knowledge saves homeowners money by getting solutions right first time, avoiding the costly mistakes we've seen from contractors unfamiliar with Wandsworth's quirks.
