Abstract: |
A watching brief of geotechnical boreholes at Merchant Waste Treatment Plant, Frog Island, London Borough of Havering. The geotechnical work comprised the excavation of 12 boreholes between the 18th and 28th January 2011. The work demonstrated that river terrace gravel was present at approximately 10m below the current ground surface. Overlying the river terrace gravel was approximately 7m of alluvial deposits containing various accumulations of peaty material. Overlying the alluvial sequence was approximately 3m of modern made ground. Some of the boreholes revealed peat deposits towards the bottom of alluvial sequence of some thickness (up to 3m). Core samples removed during this watching brief should provide significant material for palaeoenvironmental analysis. |
