February 24th – The huge marlpit at Stubbers Green that feeds the Weinerberger brick plant with raw clay is impressive. These extraction processes are not as simple as just digging a hole. The pit is dug in a pattern decided by engineers to ensure safety and drainage. In an impervious material like marl, accumulated water from the elements and surrounding environment is an issue to contend with. Here, a floating pump on a bouyancy raft made of empty drums returns water to a surface lagoon. Roadways and access tracks crisscross the site.
Extraction didn’t seem to be in progress when I passed today, but excavators load huge trucks with the red, surprisingly dry material, which is conveyed to the plant on the far side in an endless chain. The factory was running, however, as I could smell the distinctive note of baking clay in the air.
Although ugly, and many consider it a blight, this is a factory and facility that provides much employment to the local area, and the bricks produced are good quality. I find it fascinating in scale and procedure, and could look into that void for hours.
One of the fascinating aspects is looking at the rear face, and seeing the subtle colour changes in the clay as the geology yielded its secrets.
