This was an early Roman Cement producing site, well placed for landing dredged septaria from both sides of the Thames estuary. Portland cement manufacture began much later. The original Portland plant probably had a few bottle kilns, but these were replaced by four Johnson kilns (100 t/week) in 1890. To this was added a block of three chamber kilns (80 t/week) before 1896. By 1907, the number of chamber kilns had risen to 18 (520 t/week) and a Schneider kiln (80 t/week) had been added, bringing total capacity to Davis’ 1907 total of 600 t/week. The plant used both rail and water transport throughout its life. The plant was shut down in on 4/3/1912, and was completely demolished by the end of the year, the site now being occupied by light industrial buildings.
Power supply
The plant was direct-driven by steam engines.
