What are Helical Piers?
Helical piers serve as foundation support systems comprising steel shafts with spiral-shaped blades.
Employing hydraulic equipment, these piers are inserted into the ground and can provide support for both newly constructed and existing buildings.
They are particularly useful in cases where the soil lacks the strength or stability required for conventional foundation techniques like driven piles or drilled shafts.
Helical piers are also preferred in areas with restricted space for machinery, making them well-suited for compact urban locations.
How are Helical Piers Installed?
The installation of helical piers is tailored to the specific application.
When placing them beneath an existing structure, the process involves excavating the designated area. Subsequently, hydraulic methods are employed to drive the helical piers into the ground, with a pressure gauge guiding the depth of penetration.
The required number of piers for a project varies, and they can be cut to the appropriate lengths. Attaching the piers to the structure is facilitated through brackets, with some necessitating interior installation.
Once the piers are securely in place, the jacking process commences. Upon achieving the desired height for the structure, the installation crew completes the restoration of the site.
How Much Do Helical Piers Cost?
Opting for helical piers for foundation repair offers greater versatility compared to alternative support choices.
The cost of helical piers can range from $1,750 to $3,000 per installed pier. On average, the installation expense hovers around $2,375 per pier. Expenses can vary depending on additional requirements, such as concrete.
As previously noted, the cost of piers can range from $15 to $30 per foot, with the overall cost influenced by the length and size of the piers.
Factors influencing installation costs include the quantity of piers needed and the condition of the soil. Piers equipped with brackets will raise the cost, whereas those featuring beam caps may incur lower expenses.
Despite the variable costs, choosing helical piers can be a cost-effective solution, potentially saving you from the expense of a new concrete foundation.
