Push Pier Foundation Repair

We install a few different types of foundation repair products, one of which is push piers, which are also called resistance piers.

Push Pier Foundation Repair

Concrete Jack’s foundation repair experts are factory trained installers of Earth Contact Products‘ line of foundation repair products, including push piers (ECP Steel Piers).  Push piers are pushed into the ground until they reach a layer of solid soil which can support the weight of the structure.  After the solid layer is reached, the piers serve as a point to lift the foundation, bypassing the unsuitable layers of soil.  Push piers are frequently also called resistance piers.  Some of the frequent piers we install are ECP Model 300, ECP Model 350, and ECP Model 250 push/resistance piers. Push piers use the weight of your foundation as the resistance to drive the pier into the ground.  Push piers are well-suited for foundation repair in areas where there is a suitable layer of strong soil below the structure, such as rock.  Concrete Jack installs steel piers, which are usually galvanized, given the coastal location of much of our service area. Eccentric push piers require a few feet of overhead clearance, so are typically not installed in crawl spaces.

Advantages of Push Piers

Push piers are one of the most frequently-installed piers, because installation is simple.  Because the weight of the structure is used as the resistance to installing the pier, load testing is immediate and it is easy to determine the ability of the pier to hold up the weight of the structure. Another advantage is that no equipment is required for the pier installation.  For structures with shallow footings, access holes for installation are generally dug by hand.  In some cases, it is faster and less expensive to use a small excavator to dig the access holes, but the excavator is not required for driving the piers.

Disadvantages of Push Piers

Push piers are only as good as the structure that they’re installed under.  Therefore, push piers aren’t a good choice when building loads are anticipated to increase, there is extensive cracking or deterioration of the foundation, or when the structure is so light that it doesn’t provide enough resistance to push the pier sufficiently into the ground.  Most single story structures, particularly with short block walls, wood framing and siding, are too light to be sure push piers can be driven to an adequate depth.  In these cases, helical piers are generally the most appropriate foundation repair method.
