What Are Helical Piers Used For?
Foundation settlement is a common issue for many homeowners. Over time, the sheer weight of your home can cause it to sink into the soil below, creating an uneven surface that can put serious strain on your foundation and cause things in your home to tilt or shift. One way to counter this is foundation piers. In this article, we’ll explore how they work and the benefits they provide to shifting or unsteady foundations.
What Are Helical Piers For?
Helical piers are deep foundation solutions used to support structures, particularly in situations where soil conditions are challenging. These piers are made of steel and feature uniquely shaped plates, arranged in a downward twisting pattern, that allow them to be screwed into the ground. They provide a stable foundation by transferring the structural load to deeper, more stable soil layers or bedrock.
One of the key advantages of helical piers is their versatility and ease of installation. They are particularly useful in areas with poor soil conditions, as the helical shape allows them to burrow under tough, rocky soil. Helical piers can be used for underpinning existing structures that have experienced settlement or shifting, providing a practical solution for foundation repair and stabilization.
How Are Helical Piers Installed?
Installing helical piers on a sunken foundation involves a precise process to stabilize and lift the structure. First, the areas where foundation settlement is the most severe are identified. Small sections of the foundation are excavated to expose the footing. Next, helical piers are driven into the ground adjacent to the foundation using hydraulic machinery, screwing them into the soil until they reach stable, load-bearing strata.
Brackets are then attached to the helical piers and connected to the foundation. Hydraulic jacks are used to lift the sunken sections of the foundation back to their original position. Once the foundation is level, the piers and brackets are permanently secured, ensuring long-term stability and support.
