How Can You Repair Foundation Movement?
There are a few different ways experts fix foundation movement.
- Compaction grouting – This is when experts inject fast-setting polyurethane foam into any loose soil underneath your foundation. The foam expands and hardens, forming balls or columns of dense structural supports. Overall, the process compacts the surrounding weak soil and increases the load-bearing capacity.
- Permeation grouting – This is when experts inject cement or a chemical-based grout underneath your foundation. This injection fills any pockets in the dirt and turns granular (weak) soil into a solid mass with increased support capabilities. Permeation grouting is commonly used in coastal regions where the soil is usually sandy or loose.
- Steel push piers – These piers are pushed deep beneath the soil under your foundation until they reach load-bearing strata (soil strong enough to support your home’s weight). Once they reach that soil, hydraulic jacks are attached to the side of your foundation and push down on the piers, using the pressure to lift your home.
- Helical piers – These piers are also used to lift settling foundations and homes. Instead of being pushed into the soil, they are twisted like corkscrews until they reach load-bearing strata.
- Wall plate anchors (for poured concrete block walls) – If you have a basement, and your foundation walls are bowing (the center of your wall is pushing inward), then experts will use wall plate anchors to correct the movement. Wall plate anchors work in three parts: the anchor, the plate, and the threaded steel beam that connects them. The plate is placed inside your bowing wall, while the anchor is placed in a trench in your yard. The steel beam is slipped through your plate, wall, and dirt until it reaches the anchor outside. Once they are connected, the plates are torqued, which pulls the wall outward and corrects the movement.
- Helical tieback anchors – These anchors accomplish the same goal as wall plate anchors. Instead of using a separate outside anchor, the beams are twisted into the dirt from inside your basement like corkscrews. As they twist, they pull your wall back outward. These anchors are useful for homes that have limited space outside their foundation.
- Carbon fiber repair – Experts can use various specialized carbon fiber equipment to correct bowing walls and foundation cracks. Carbon fiber is an extremely strong material and is virtually unbreakable.
