Clinker manufacture operational: 1869-1903

Approximate total clinker production: 49,000 tonnes

Raw materials:

  • Chalk and Alluvium shipped in: source unknown, but probably one of the Portsdown quarries supplied Upper Chalk (Newhaven Chalk Formation: 82-85 Ma), and the alluvium may have been dredging, or the clay matrix (probably Kimmeridge Clay Formation: 151-156 Ma) from which septaria had been obtained.

Ownership:

  • 1869-1903 Hooper and Ashby
  • 1903 Sussex Portland Cement Co. Ltd

It seems likely that Roman Cement had been made here from as early as 1812, using the local septaria: this plant is shown on early maps. A separate Portland cement plant was built adjacent to this in 1869. There was one wet process bottle kiln, output 30 t/week. Another two kilns were installed in the 1890s. All transport was by water. The site became a depot for Shoreham after the SPCC takeover, served by rail using the LB&SC Southampton docks branch. The site is now part of a boat yard and marina.

No rotary kilns were installed.
