Excavation of the EBS - Removal of Layers 6-5

Layer 6 and layer 5 were the bottom layers of the silo to be excavated.

Due to space limitations the excavation of the sand/bentonite was more difficult in the lower areas and excavation techniques had to be adapted to take account of the reduced space.
