Monument record HWT 038 - Peat Layer, Brook House, Quay Street, Halesworth, Suffolk

Ground works for a side extension were limited to screw piles and construction on these from ground level monitoring of the excavation of a treatment plant pit to the rear of the house recorded a substantial deposit of alluvial material above an organic silty layer. In this context it is worthwhile noting that the 70m long garden to the rear of the house backs onto the River Blyth so the alluvial deposits are likely to have been caused by past flood events and Quay Street to the front of the house probably runs along the northern edge of what was the floodplain (S1).
