Getting a shed base right in Croydon's clay-heavy soil isn't something you want to rush. Years of dealing with subsidence issues across CR0 and CR2 have taught us exactly how to create foundations that actually last.

Most Croydon gardens sit on London clay - brilliant for keeping moisture in summer, but notorious for movement through the seasons. That's why shed bases here need particular attention to drainage and depth. Whether you're tucking a small store behind a Victorian terrace in South Croydon or planning something larger for those generous 1930s plots around Waddon, the groundwork determines everything.
Proper excavation depth varies dramatically between addresses. Properties near Wandle Park often hit gravel quickly, whilst Selhurst gardens might need 450mm before finding stable ground. Compacted MOT Type 1 creates the crucial drainage layer, followed by sharp sand leveling. Concrete thickness depends entirely on your shed's weight - heavier workshops demand 150mm minimum, whilst lightweight stores manage with 100mm.
Since 2008, we've installed bases for over 400 Croydon properties. Local builders merchants know us by name, which means material deliveries arrive promptly - no waiting around whilst your garden stays excavated.

Most 8x6 bases in the CR0 area run between £650-£850, depending on ground conditions. Clay soil near Purley Way usually pushes costs higher due to extra excavation needs, whilst sandier patches around Lloyd Park keep things simpler.
Absolutely - from Forestdale in CR0 right through to Thornton Heath in CR7. Regular work takes us through South Croydon's leafy streets (CR2) and we know the access challenges of those narrow Victorian passages well.
Booking slots typically open within 5-7 working days. Actual installation takes one day for standard bases, though particularly waterlogged gardens occasionally need two days for proper ground preparation.
Each base carries decade-long protection against structural failure. This covers settlement cracks, frost damage, and drainage problems - basically anything that stops your shed sitting level and dry for ten full years.
Croydon's mix of hill positions creates plenty of sloping plots. Retaining edges, stepped bases, or part-excavation into banks all work depending on your specific levels. Those tricky spots beside garages or against boundary walls just need creative shuttering.
