Sometimes referred to as Onward Works. Weston had previously made Roman Cement at Millwall, and may have continued producing it in a small way at this site. The Portland plant apparently began with nine small chamber kilns (output 130 t/week). Three more sets of three were added – 85 t/week around 1881, 95 t/week around 1888 and 75 t/week around 1899. The plant used water transport, although a rail link was later made. After closure, the site stood derelict until in the 1930s it was absorbed into the adjacent Britannia Lead Works. It is currently under port facilities.
No rotary kilns were installed.
