Cracks in the joints of a concrete block basement wall
These kinds of cracks are often called stair step cracks because they resemble a set of stairs. Sometimes they require wall anchors, sometimes helical piers or push piers.
Horizontal wall crack in a basement wall
When the inspectors see big cracks like this its a major issue. Often times the homeowner has no idea that it can even be fixed. Many times a crack like this will need immediate attention in the form of wall anchors, carbon strapping, or power braces.
Hand dug hole for the earth anchor
Most times its just easier and quicker to dig the holes by hand. These guys are real pros, you can see how straight and clean the edges are. This assures that the earth anchor will fit snugly and properly.
Earth anchor before the rod is tightened
The earth anchor is connected and then the rod is pulled tight. This is a lot like when a child gets dental braces, they tighten slowly and a little on each anchor before moving to the next one.
Wall anchors in place
The exact spacing is determined onsite. Each anchor is designed to hold quite a bit of the load.
