Response within 24 hours
Those steep gradients running down from Sydenham Hill create unique challenges for foundation work throughout SE23. Victorian properties along Honor Oak Road often need underpinning solutions, while newer developments near Forest Hill station require careful consideration of the area's notorious London clay. Every project starts with understanding your property's specific ground conditions and structural requirements.
Ground investigation reveals crucial details about soil composition, water table levels, and load-bearing capacity specific to your plot. Strip foundations suit stable ground conditions found in parts of Dulwich borders, whilst piled solutions tackle problematic clay shrinkage affecting many Forest Hill gardens. Modern reinforcement techniques ensure longevity whether supporting a rear extension or stabilising period property walls. Structural calculations determine exact depths and widths needed for your particular build.
Twenty years navigating SE23's geological quirks means anticipating issues before they arise. Local building control officers know our work meets their stringent requirements first time, avoiding costly delays on your project.
