Abstract
The construction of Port Solent Marina involved the removal of alluvial silt to expose a layer of reworked chalk which acted as the foundation for a land reclamation project utilizing 564 000 m3 of Ports Down chalk as fill, up to 5m thick. A "thick layer' compaction specification was developed to preserve the lump structure of the chalk and avoid instability. Careful methods of working produced a successful fill which could support a foundation pressure of 167kPa with less than 10mm settlement. Settlement of the underlying natural ground was shown to be virtually complete by the end of the filling operation. No measurable effects of groundwater movement were detected.
