Here you can see the concrete truck pouring concrete into the pump truck, which pumps the concrete through a large boom, which is being directed into the foam blocks. David took a video of the concrete going into the blocks, so I am going to try to link it here. It also shows them vibrating the concrete after it is poured, which is important so that there are no voids in the concrete.
There was one "blow out", where one of the ICF blocks broke and concrete (about a yard) came pouring out. They patched the hole and repoured the area. They think that the ICF may have been cracked during all the attempts to get the walls square.
After all the assurances that the walls would be leveled after the concrete was poured, we now have walls that bow out in places. Not a big deal at this stage, but we will be on top of it during the next pours.
The contractor's dirt sub-contractor recently lost all of his equipment in a fire, so they have been calling around to find someone new. We get to be the guinea pigs! The new sub came out yesterday, and David was happy with his knowledge. They will probably do the dirt work on Tuesday. I calculate 430 cubic yards needed to fill the walls in, plus another 50-100 for the driveway ramp.
