Those sloping Lewisham gardens need solid foundations that won't shift with the clay. Whether it's a shed tucked behind your Victorian terrace or a garage for that narrow plot, getting the base right matters.

SE13's mix of housing throws up interesting challenges when laying concrete bases. The terrain drops sharply towards Catford, whilst Blackheath-facing properties battle different soil compositions entirely. Years of working these streets means understanding which reinforcement methods suit each particular plot - from the compact gardens near Ladywell station to the more generous spaces heading towards Manor Park.
Proper excavation depth depends entirely on what's going above and what lies beneath. Clay-heavy sections require deeper digs and membrane barriers to prevent seasonal movement. Steel mesh reinforcement becomes essential where tree roots from those mature London planes might cause future upheaval. Mix ratios adjust based on load requirements - a greenhouse base differs vastly from foundations supporting a double garage.
Local knowledge counts when navigating Lewisham's quirks. Access through narrow Victorian side returns, working around preservation orders near the conservation areas, understanding which properties share drainage - these details shape successful projects.

Basic 8x6ft shed bases generally run £400-600, though sloping gardens or poor access can push costs higher. Larger workshop bases (12x10ft) typically fall between £800-1200 depending on ground conditions.
Absolutely - from Hither Green's railway cottages to the newer developments near Lewisham Hospital. Regular work takes us through Ladywell, up towards Blackheath borders, and across to the Catford Bridge area.
Most projects start within 8-12 days of confirmation. Smaller bases often complete in a single day, whilst larger garage foundations might need 2-3 days including curing time.
Every base carries decade-long protection against settlement or cracking. This covers both materials and workmanship, with annual checks available for the first two years.
Depends on the damage extent. Minor surface cracks might allow overlay solutions, but bases showing movement or deep fractures need complete removal. Old concrete often becomes hardcore fill for the new excavation.
