Garage Floor Replacement Pt.2

This morning they are digging out along the footers to put in ECP push piers. There was a small crack in the stem wall near the window. This crack propagated through the bricks on the outside of the house. Normally they would dig from the outside and put in the push piers, because they were replacing the slabs they did this from the inside.

 Here's a shot of where the stem wall was cracked. Right next to it where the concrete is freshly chipped away is where one of the ECP push piers went in. In total they installed three of them along the wall. They will re-pour the slabs in two days.

I could not stay for the installation, but the piers are installed like the diagram below.

Here is a shot of the outside wall just below the window. I am no expert on this but I have never heard of bricks cracking in half. Every time I have seen this it was just cracks in the grout.
