If your house is tilting or cracking, finding a solution can be difficult. Different contractors offer different solutions, some of which sound great and some of which are really only a temporary band-aid. We’re going to learn what push piers are, how they are installed, when they should be used, and their pros and cons.
What are push piers? Push piers are made with heavy duty steel and connect to your foundation with a bracket. Like helical piers, push piers are driven into the soil one section at a time until they reach load-bearing soil or bedrock. The steel brackets that connect the piers to your home’s foundation transfer the weight of the home down to this more competent soil. You don’t want your repair system to use the same unstable soil that caused the problem in the first place- soil in the active zone. When your house rests on competent soil it will stop settling.
How are push piers installed? They can be installed outdoors and indoors.
Step One: Outdoor: Soil has to be removed from around your foundation’s footing for each pier. Indoor: The concrete floor will be removed in an area that is about three by three to access the footing where each pier will be installed.
Step Two: A specifically engineered steel bracket is placed under each footing location.
Step Three: Steel pier sections are hydraulically driven through the bracket to load-bearing soil.
Step Four: The weight of the home is transferred from the foundation through the bracket and piers into the load-bearing soil. It can then be decided whether or not it’s a good idea to lift your house to its original position.
Step Five: The soil is back filled or the concrete replaced and your home is stabilized.
When should you use them? Push piers can be used in most crawl spaces, indoors and outdoors, if you want a relatively quick installation, if you want to lift your home to its original position, if you want a permanent solution, and they are the least risky solution when soil conditions are unknown. This is one of the differences between push piers and helical piers, since helical piers require an intimate knowledge of the local soil but push piers don’t while providing the same solution.
When should you not use push piers? Push piers do require the weight of the structure to help drive them into the soil, so if you want to lift a lighter structure like stairs, these might not be heavy enough to drive the push piers to a sufficient depth. Helical Piers are more ideal for this.
Pro 1: They can reach greater depths because of a specifically
designed starter tube that has a friction reducing collar. Not all systems can go as deep.
Pro 2: The push pier system by Supportworks has a patented bracket and external sleeve that resists bending and ensures a vertical installation to load-bearing soil.
Pro 3: Available in galvanized steel that resists rust.
Pro 4: it’s underground so you’ll never see it.
Pro 5: Gives you the best chance to lift your home back to its original position. Helical piers can do that too but it requires more engineering costs, soil boring samples, heavy equipment, and excavation. It requires the removal of decks, patios, entryways, and shrubbery. Not so with push piers. Since push piers rarely require a soil boring sample, this makes the installation relatively quicker.
Pro 6: You generally don’t have to replace your foundation. Our push pier system allows you to fix the one you already have.
Pro 7: Push piers don’t require heavy equipment, and this makes it ideal for relatively tight spaces where such equipment can’t be used.
Con 1: A non Supportworks push pier system can bend and rust over time. This is why our push pier system by Supportworks has an external sleeve that stops this. Supportworks push piers resist rust because they have the option of coming in galvanized steel but that’s not the case with every push pier system out there.
So our push pier system is the one we recommend and trust the most for the majority of situations where your house is settling.
