Let’s discuss how underpinning can help secure your foundation and protect what matters most.
What is underpinning?
Foundation underpinning is the process of securing your structure by reaching past the weakened soil your foundation is currently built on and transferring the weight of your foundation to soil that can support it. Soil that is closer to the surface is more susceptible to compression and settlement, whereas deeper soil is denser and capable of supporting heavier loads without sinking. Thus, this method of foundation repair directly addresses problems caused by expansive soil or excessive moisture, as underpinning methods like helical piers and slab piers can adjust your home’s weight to rely on deeper, more competent soil.
What are the common uses for foundation underpinning?
Because foundation underpinning is a reliable method for strengthening and stabilizing foundations, it’s used widely for a variety of projects. Some of the common uses of underpinning include raising uneven concrete foundations and slabs, stabilizing conditions prone to causing sinkholes, treating expansive or weakened soil, and strengthening foundations built on weak soil. Though underpinning is often associated with foundation repair, it can also be used in preparation for new construction or a change in the purpose of a structure. Making additions to a building or placing more weight on a structure requires a stronger, more capable foundation. Underpinning your building’s foundation in preparation for increased load-bearing requirements can help prevent foundation damage and structural instability in the future.
How is Foundation Underpinning Used for Foundation Repair?
Underpinning methods help your foundation when your foundation starts settling due to unstable soil. Some underpinning methods involve stabilizing your foundation by pouring concrete into excavated sections underneath your foundation, but the more common methods involve installing helical or slab piers that reach deep into the earth. These methods are minimally disruptive so that you can maintain your routine while our expert staff performs the installation.
What is the Underpinning Process?
The underpinning process begins with excavating soil beneath your home or structure’s existing foundation in stages. These stages are important to the process as they prevent undermining the building’s current foundation and causing structural damage. These stages are called “pins,” and as each stage is completed, the soil is replaced with new foundation support. These “pins” are repeated until the entire length of the load-bearing wall is reinforced.
