What is the ground like in East Sussex?
Inland East Sussex is Weald Clay and Wealden sands, while the South Downs and the coast around Brighton and Eastbourne are chalk. The Weald Clay areas are prone to shrink-swell movement near trees.
Ground movement here is more often linked to soils, drains and trees than to mining.
