When a foundation is damaged, there are lots of different ways a damaged foundation can be dealt with. How the foundation is fixed really depends upon the specific foundation issues with your home.
#1 Spot Piers
A spot pier is a pier that is dug out by hand, not using any fancy equipment. The holes for the pier are then filled in with concrete. Spot piers are used for shallow foundations. These types of foundation repairs are generally used for fixing lightweight foundation issues, such as the foundation for a porch.
#2 Steel Piers
Steel piers are a very popular way to stabilize a foundation. They do not take too much time to install and do not require extensive excavation and modification of your landscaping.
Steel piers can handle a fair amount of weight, and technical modeling features, driven by data, are used to determine where a steel pier should go.
#3 Concrete Piers
Concrete piers are typically used to create foundations in the first place. They are usually used in pre-construction. Concrete piers can also be used to fix a damaged foundation as well. However, concrete piers are a little more complicated to use for fixing a damaged foundation.
In order to install a concrete pier, extensive excavation and digging has to be done, which means tearing up the landscaping around a home in order to stabilize the foundation. This process can drive up the overall cost of the project. It can also be difficult to get the drilling rigs necessary for installing concrete piers onto completed residential properties.
Concrete piers are a strong stabilizing force; however, they can be difficult to put in place after the initial construction period.
#4 High-Density Polyurethane Foam
High-density polyurethane foam is commonly used as a tool for repairing a damaged foundation because of how flexible the foam is. It can be injected into a mold or directly into the impacted area. The foam expands and helps lift your foundation up.
The only real downside to using foam to fix your foundation is that it can be damaging to plumbing and HVAC pipes if it is injected anywhere near them. The foam is designed to expand significantly after it is injected, and should only be used away from plumbing and heating pipes.
If your foundation is damaged, get help right away before the situation gets worse. A professional can help determine if spot piers, steel piers, concrete piers, or high-density polyurethane foam is the best foundation repair solution for fixing your foundation and saving your home.
