Below grade waterproofing- June 2007

This series of photos shows how we finished plastering the part of the dome that will be below natural grade (underground) and then applied a coat of asphalt emulsion for waterproofing.

Beautiful summer sunrise -- the early hours are the best time to work now that the desert is heating up. The white line marks one foot above natural grade.

Next we put on a smooth coat of plaster using steel trowels.

Looks cool...

With that completed we were able to get a machine to backfill all the area surrounding the dome.
