Push piers are designed to transfer the weight of your home and all its contents to load-bearing soil or bedrock. This permanently stabilizes your home’s foundation, and in many cases can lift a sunken foundation back to its original position. This is achieved by driving the pier deep into the ground until it finds this competent soil or rock. Homes are typically stabilized with multiple piers — as few as three or four piers to as many as 40 or more, depending on the size of the home and the scope of the work required.
NSquare uses Supportworks push piers that are made from heavy steel and are engineered to be extremely strong, durable and to bear enormous weight. Supportworks push piers also feature specially designed proprietary elements that enhance durability and effectiveness.
Installing a Push Pier System
As mentioned earlier, push piers work by transferring the weight of your home to stable soils or bedrock. This is done by supporting the foundation’s footing. So, the first step in a piering installation is to expose this footing by excavating dirt around it. Then a proprietary heavy-gauge steel bracket is placed under the footing. Steel pier sections are then hydraulically driven through the bracket until they reach stable soil or bedrock. Once all the piers are installed, a lift can be attempted. When the installation is completed, the excavated soil is put back, covering the footing and its brackets.
Push piers are ideal for stabilizing heavy structures, but they may not be ideal for lighter structures that may not provide enough downwards force (reaction) to push them deep into the ground. In those cases, helical piers may be more appropriate.
The primary advantage of a push pier system is that it stabilizes your home’s foundation permanently and may even be able to lift it back to its original position. In addition, the installation of a push pier system can be completed in a matter of days. Total foundation replacement, typically takes much longer, costs more and does nothing to address the issue that caused the problem in the first place: poor soil beneath the foundation.
