How Do Pier Systems Work?

There are many options available for pier systems, including slab piers, helical piers, and push piers. These systems all have special unique features, but they also have some features in common overall. Here’s how a pier system works in general.  

• Drilling Down into the Earth  

The first step is the method by which an expert will be able to install the piers. This may vary depending on what type of pier system they are installing. For example, the expert may drill through the foundation concrete or use foundation brackets. Then, the expert will drill steel tubes down until they reach the correct soil layer.  

The correct layer of soil may differ depending on the pier type and the location. Some homes may require that the piers go all the way down to bedrock, while some homes may be able to reach down just a bit and access more stable soils. Either way, an expert will be able to tell when they’re able to stop driving pier sections through the foundation.  

• Lifting Your Foundation 

The next step is to use the pier section to actually lift the concrete foundation. This requires that the expert transfer the weight of the foundation from the current soil it’s sitting on to the deep soil that the pier is sitting on. From there, it’s possible for the expert to attempt a lift, which will bring the foundation back to its original place.  

Once the foundation has been lifted back into place, it  will be stabilized by the piers and can be used like normal. There is no set-up time or process required. Once the piers are in place, they can ensure your foundation is properly supported and safeguarded against future strain. This is best paired with annual maintenance checkups to ensure that none of the problem signs return later on due to other factors.
