With the hollow core concrete panels in place, we have two tasks to complete.
First, we have to place dry pack in the voids, or gaps, under the steel columns and beams. At the same time, we have to move 160 yards of soil to fill the void between the swimming pool and the foundation wall.
Placing Dry Pack
Our steel beams are connected to the concrete with embedded bolts. There is a 1½ inch gap under the steel plate that the embedded bolts are connected to. After the steel is in place, the resulting gap is filled with ‘dry pack’ and allowed to set.
Using dry pack under the steel beams allows the full weight to be distributed evening to the concrete surface.
