The plant initially made lime. A D Robertson, having run the plant, moved to Grays to set up the more important Wouldham (Essex) plant, confusingly transplanting the place name. There were four bottle kilns for Portland cement in 1869. In the late 1880s, these were replaced with six chamber kilns, and a further eight were installed in the early 1890s, giving a total 350 t/week. With the APCM takeover, there was little point operating the plant alongside the nearby Burham, which was earmarked for expansion. There was no rail, and essentially all transport was by water. The plant site was cleared, and is now under housing. The quarry remained open for some time as a supplementary source of chalk for the Frindsbury plants, and is now waste land.

No rotary kilns were installed.
