Bear Creek Dome Concrete Pour

Tuesday, 20 degrees Fahrenheit.
Pumper truck arrives 7:30am. First cement truck arrives 8:00am.
Ready to pour. The driver controls the cement truck from inside his cab.
The pumper truck, hopper, & cement flow is controlled from the operator inside the dome.
A “slurry” mix of water & concrete is pumped through the hose to get started – then the action begins.
The pump actually shoots the concrete out 8′-10′.
A laser beam with a remote sensor on the rod is used to check the height of the concrete.
A power screed is used to level the first time.
Work progresses quickly while the crowd looks on.
“Zip strip” control joints are placed to control drying cracks.
The total pour involves approximately 2100 SQ. FT. With footings the total is 40 cubic yards.
The final few yards are poured directly from the truck chute. Sam’s Masonry workers back themselves out the door at 10:15am. Without the pumper truck, they would still be wheelbarrowing concrete.
Now we wait a few hours.
The entire slab was finished with a circular power trowel and then hand troweled because we are going to stain the concrete as the final floor
finish in all the rooms.
Anyone for roller skating? We had to scratch the proverbial dedication into the concrete as the final step.
