History
On the Redhill deposit, the most successful quarry operating at the turn of the century was the Copyhold Works of the Fuller’s Earth Union Ltd, established c.1860-70. Initially supplying the woolen trade, demand later shifted to the growing chemical and comodity sector with customers in the 1920s-40s including the Southern Oil Company Ltd, British Glues and Chemicals Ltd and Price’s Patent Candle Co.
In 1954 the works, by now employing 780 men, were bought by chemical company Laporte Industries. Production was stepped up to meet increasing demand and a large factory consisting of kilns, granulators, blungers, silos and transit systems on several floors was built. A large quarry existed to the east and in the 1970s this strange landscape stood in for various alien worlds in the BBC’s Doctor Who series. In the 1980s, the Copyhold site was sending loose earths and packaged cat litter around the world.
By 1995, however, due to falling profits it was announced that the company would close 10% of its 100 plants. Copyhold fell victim the following year and the Laporte Group ceased fuller’s earth production altogether in 1997. After the production lines were switched off, the 119 acre pit was purchased for use as a landfill site by Biffa Waste Services and continues to take waste from across Surrey. The factory was for a while used as a waste transfer station but this was abandoned at some time in the last four years and the site is now derelict.

This was another place I visited with @CuriousityKilledTheCat in what turned out to be a very industrial based day - an enjoyable one nonetheless. had no info on this one - just a set of coords, and being in the area we thought we'd stop by and i'm glad we did! was pretty much a walk on, but the stupid rain resulted in us getting soaked and caked in crap, but it was worth it! Bumped into a couple of other explorers here and had a quick chat, but we were in and out within an hour. nice little place to stop by if you're in the area!
as always, thanks for looking!
