Tauchbasis Kreidesee - Concrete rubble silos
Channel: Tauchbasis Kreidesee

These are about 1.5mx2m large vats that are generally found on construction sites today. During cement production these were used to fill several machines and furnaces with ground chalk. Originally two "concrete-bombs" were settled at a depth of 45 meters, below the steep slope at entrance 1. To allow beginners to view the silos one was raised in 1996 to a depth of 23 meters and stood up right next to the curbstone. The rubble silos are marked with buoys.
