15 auger holes which were drilled to a maximum depth of 10 m have shown a gently dipping sequence of Quaternary silt and clay, passing down at about 6 m depth into a dense Tertiary sandstone. The highly calcareous, plastic silt which occurs immediately beneath the topsoil would provide a suitable foundation for light structures, but requires field density checks as it may be of windblown origin and thus have collapse potential. A stiff mottled clay, occurring at depths of up to 2.5 m, forms a more certain bearing horizon which should have adequate strength for supporting large structures. Both the silt and the mottled clay are highly plastic, and so establishing effective drainage for rainfall infiltration, particularly away from footings, will be an important factor on this site. No groundwater was encountered.
