Abstract: |
CgMs Consulting Ltd commissioned Pre-Construct Archaeology (PCA) Ltd to undertake an archaeological watching brief on geotechnical works at 150-152 Long Lane, London Borough of Southwark SE1. Naturally occurring gravel deposits were observed in both boreholes at a height of between -2.4m BGL (below ground level) and -2.2m BGL (c. 0.6m OD to 0.8m OD). A late post-medieval ground raising layer, representative of the top of archaeological stratigraphy, was recorded in Test Pit 6 and Hand Pit 2. Excavation did not proceed deeper than this level in these pits. In Hand Pit 3, the same layer was observed down to a depth of -1.5m BGL (c. 1.50m OD). It was overlain in this pit by a late Victorian to early 20th century floor with an associated brick wall extending north-south along the eastern side of the pit.Typically, the concrete foundations of 152 Long Lane were between 0.4m and 0.65m in depth, although a large pad foundation was seen at the southern end of the building that's depth was not fully exposed. Footing depths along the eastern side of the site ranged between 0.5m and 0.75m in thickness. Modern brick rubble deposits in places up to 0.75m thick were recorded across the study area. These were sealed by a reinforced concrete slab measuring between 0.15m and 0.5m that was in turn sealed by between 0.04m and 0.1m of tarmac |
