First they needed to use the air compressor to spray off any debris on the footer where the shotcrete needs to stick at the base of the domes. Very dusty.
As soon as the concrete truck arrived they were getting suited up to start spraying an I had to get into the dome to make sure I was ready to get video before they started.
When the Concrete truck arrives, things move fast. Here is the video sped up to about 600%.
And there was a blow out in the hose! See the concrete up and to the Left of where they started spraying. So that hose had to be swapped out.
Back at it after changing out the hose.
And finally after 2 trips around they have their first pass up over 10 foot.
They will do a couple more passes on the lower levels before they start on the overhead spraying.
