Push piers, also known as resistance piers, are used to correct foundation settlement. If your garage were sinking, for example, push piers would be used to lift and secure that section of foundation. Push piers are used for commercial buildings, residential homes, and even brick structures.
A push pier is capable of holding a significant amount of weight, making it a good solution for a damaged foundation. Weak and unstable soil that shifts and settles over time can cause columns and beams to shift out of position. This leads to a weakened foundation. Here’s what you should know about the different types of push piers:
Eccentric push piers are made of steel and the most commonly used foundation repair system used these days. These push piers can be installed from the inside or the outside of the structure. The steel tubes utilize the weight of the structure to hydraulically drive the piers to bedrock or other competent load-bearing strata. The strata is a layer of sedimentary rock or soil. Piers are space a maximum of six feet apart in order to ensure stabilization. With an eccentric push pier system, the pile axis is not in line with its applied load.
Concentric push piers are also made of steel that are a lower tech solution compared to the eccentric push piers. This system eliminates shims and bottle jacks from the lifting process. These push piers will be in line with its applied load. This design ensures years of structural support. Concentric piers can make a good solution for crawlspaces, as they don’t need a tall drive stand. These push piers will also not be hindered by deep brick ledges or other obstacles.
Crawl Space Jack
The crawl space jack provides support to sagging floors above crawl spaces. This will help to reduce or eliminate squeaking and bouncing caused by a damaged foundation or lack of adequate support caused by improper spacing of crawl space pier columns. If they have been space too far apart, crawl space jacks can help to make up for the lack of support. Crawl space jacks are economical and easy to install.
There are many variables when it comes to choosing a push pier system. You need to consider where the support is needed and what kind of obstacles might be present when installing the push pier. For whatever situation you’re dealing with though, there is an option. You can have a professional come in and access the damage and decide what’s right for your home’s unique foundation situation.
