Fall 1997

The trench has been uncovered; the curved pieces of corrugated iron lie on the right-hand side. The bales of rockwool have been distributed along the trench. Zoom Image

Wrapping the tubes is no easy work. You have to protect yourself against the inhaling of small particles of rockwool. Here you see Jochen disguised up to his nose and eyes. Zoom Image
