Biggin Hill's elevated terrain demands groundworks expertise that understands chalk substrates and sloping gardens. From RAF heritage homes to modern developments, proper foundation work makes all the difference.
Response within 24 hours
Those stunning views from Biggin Hill come with unique ground challenges. Clay caps over chalk, natural springs, and gradient issues affect most properties between the airfield and Leaves Green. Years of tackling these specific conditions mean we anticipate problems before they arise, whether you're extending a 1930s semi or installing drainage for a converted barn near Aperfield.
Ground investigation reveals surprises beneath TN16 soil regularly. Chalk dissolution features create voids requiring careful filling. Former agricultural land often harbours old field drains that redirect surface water unexpectedly. Modern ground-source heat pump installations need precise excavation depths to maximise efficiency in our particular geology. Each project starts with thorough assessment, preventing costly mid-build discoveries.
Local knowledge counts when navigating planning requirements around Berry's Green and Tatsfield borders. Established relationships with structural engineers familiar with Biggin Hill's ground conditions speed approvals considerably.

Foundation work for extensions starts around £8,000-£15,000. Full driveway excavation and preparation typically runs £12,000-£25,000 depending on gradient. Drainage solutions for hillside properties range £5,000-£18,000.
Absolutely - from Saltbox Hill to Jail Lane, including properties near Keston and across to Westerham borders. TN16's varied topography is familiar territory.
Foundation excavations usually complete within 5-8 days. Concrete curing adds another week minimum. Complex drainage systems involving soakaways might extend to 3-4 weeks total.
Every structural groundwork carries decade-long coverage against defects. This includes settlement monitoring for the first two years - particularly important given local chalk conditions. Documentation supports mortgage requirements.
Selective excavation preserves established features wherever possible. Mini-digger access through 900mm gaps protects borders. Root protection zones around significant trees get mapped before work begins, maintaining Biggin Hill's leafy character.
