Balham's Victorian terraces deserve gardens that match their character. From resolving waterlogged lawns to creating level foundations for stunning outdoor spaces, groundworks form the backbone of every successful garden transformation.

Those charming SW12 gardens often hide drainage nightmares beneath their surface. Clay soil, typical in this part of South London, combined with century-old infrastructure means proper groundworks aren't just recommended – they're essential. Whether you're battling pooling water after every rainfall or planning that long-awaited patio extension, getting the foundations right transforms everything that follows.
Modern groundworks techniques have revolutionised what's possible in compact urban gardens. Permeable paving systems now channel rainwater naturally, preventing the flooding issues that plague so many Balham basements. French drains, strategically positioned, work silently beneath lawns and borders. Meanwhile, precision excavation equipment designed for narrow access paths means even the tightest terraced plots can accommodate ambitious landscaping dreams.
Twenty years solving Balham's unique garden challenges creates invaluable local knowledge. Every street between Wandsworth Common and Streatham Hill presents its own quirks – from buried Anderson shelters to Victorian coal cellars that complicate excavation plans.
