How Does a Wall Anchor System Work?

A wall anchor system is an effective way to solve problems related to wall bowing, which might arise in your foundation due to hydrostatic pressure. Here’s how a wall anchor system really works. 

• Wall Plate 

The first main portion of the wall anchor system is the plate that goes on the inside of the wall. This is typically a square or rectangular metal plate that is fairly thick, but can go relatively unnoticed once it’s installed. Especially if you install the plate before you finish the basement, it can be very easy to add the finishing over the plate. 

This plate allows the wall anchor system to dissipate its energy over a much larger area, which means it can utilize more force overall. It also makes it much less likely that the anchor system will fail. Lastly, it helps to ensure that the wall anchor system itself won’t cause cracks in the wall, as there isn’t a single spot where cracks might otherwise form. 

• Anchor 

The other component of the wall anchor system is the anchor itself. The anchor is typically a metal rod that sits 6-10 feet into the ground outside of the wall. This is why you need at least 6-10 feet available on the outside of your basement; if you don’t, the anchor itself won’t have enough space to have an impact on the wall anchors. 

The anchor is attached to a rod, which ties the anchor and the wall plate together. An expert can tighten that rod to bring the anchor and the wall plate closer together; because of the strength of the soil holding the anchor in place, the wall plate will pull back toward the anchor, causing the wall to straighten. The distance of 6-10 feet allows the anchor to have enough staying power that it keeps the wall straight over time.
