The Land Consultancy Ltd (TLC) was commissioned to undertake a preaquisition borehole and geophysics survey of a large disused clay and sand and gravel quarry site near to Doncaster.
The sand, gravel and clay drift deposits were of Glacial origin; the water bearing sand and gravel deposits overlay the clay soils at depths of approximately 5m.
The main interest in the site was determining the volume and suitability of the clay present which had historically been extracted from the quarry and utilised to form low permeability capping layers to landfills.
