Catford's mix of period properties and newer developments each present unique foundation challenges. From narrow Victorian side returns to spacious post-war gardens, getting your concrete base right matters more than you might think.

Those steep slopes common around Forest Hill Road? They're precisely why proper concrete foundations become essential here. Many SE6 properties sit on London clay that shifts seasonally, making amateur attempts at shed bases a risky business. Years of working across Catford have taught us which areas need extra reinforcement - particularly near the old railway embankments where ground movement catches people out.
Steel mesh reinforcement goes into every base, positioned correctly to handle weight distribution. Depth calculations factor in local soil conditions - that heavy clay beneath most Lewisham properties needs different treatment than sandy patches near Hither Green. Proper membrane placement prevents moisture wicking up through your new base, whilst expansion joints accommodate natural movement without cracking.
Local knowledge beats textbook theory when dealing with Catford's varied terrain. Understanding which conservation areas restrict concrete pouring hours, knowing where old air raid shelters might complicate excavation - these details matter.

Garden office bases (3m x 4m) usually run £800-1200 in SE6, whilst single garage foundations average £1500-2000. Smaller shed bases start around £400, though sloping gardens common near Blythe Hill add excavation costs.
Absolutely - from Bellingham borders to properties backing onto Mountsfield Park. Regular projects take us through residential streets off Brownhill Road and into those tucked-away corners near Catford Bridge station.
Weather permitting, most Catford projects begin within 7-10 days. Smaller shed bases complete in a single day, whilst garage foundations typically need 2-3 days including curing time.
Each concrete base carries decade-long protection against structural failure. This covers settlement issues, cracking from ground movement, and any defects in materials or workmanship - particularly relevant given South London's clay soil challenges.
Often, yes. Those original Victorian path edgings many Catford gardens feature can be carefully lifted and reset. Block paving gets temporarily removed and reinstated, maintaining your garden's character whilst adding modern functionality.
