Stairstep Crack Indicates Bowing Wall
We could ask someone to draw us a wall with a stairstep crack and not get a better picture than this. Block walls that are leaning tend to get cracks in this stairstep pattern, where poured walls get horizontal cracks.
Level Shows Severity of Bowing Wall Problem
To measure the bow and also to give our customers a better visual on what's happening, we use levels and laser measure tapes to measure the lean of a wall.
Block Wall Falling Apart
One of the scariest things about bowing block walls is that they can just...fall apart. Where a poured wall is one large piece, block walls are made of multiple blocks mortared together. Enough pressure will break the bonds between them.
Cracked Blocks in Bowing Wall
Not only can blocks separate from each other, they can completely break apart. The further reduces the stability of the wall.
Multiple Stairstep Cracks in Wall
Doesn't that middle section look like it's just going to pop out like a Jenga piece?
Wall Anchor Installation in Progress
Cables attached to the wall anchors are secured in the soil to pull the walls straight and prevent further bowing.
Wall Anchor Brace Extensions Ensure Security
Extended brackets were used here due to the widespread nature of the bowing.
Wall Anchors Secured Away From House
The fact that the walls are bowing in the first place means the soil around the home is shifting somewhere. That would make it silly to secure the wall anchors in that same shifting soil. We take the system all the way out to stable soil and secure the anchors there.
Stabilizing Two Bowing Walls
These two adjoining walls were both leaning and cracking.
Wall Anchors in Place
As you can see, it takes a lot of wall anchors to stop a wall from caving in, but in the end it's worth it.
