UNDERPINNING FOR FOUNDATION REPAIR

If your home is experiencing foundation failure in Columbia, foundation underpinning can increase your foundation depth, 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, providing greater stability to a settling foundation. Foundation underpinning avoids the easily compressible soil and works with your foundation to make it sturdy enough to support new or existing structures. CNT Foundations provides underpinning as a foundation repair solution you can trust. Call 843-405-7022 today for your free, no-obligation estimate.

Read on to learn more about how underpinning can help secure your structure’s foundation and protect what you hold dear.

HOW DOES UNDERPINNING WORK?

Foundation underpinning increases the depth of your foundation into stronger soil. 

Soil Science

Soil that is closer to the surface is more susceptible to compression and settlement, whereas deeper soil is denser and capable of supporting much heavier loads without giving way and causing your foundation to falter. 

Why Underpinning Works

Because underpinning dives deeper, 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 where your home’s weight settles 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 widely used for all types of foundation projects. Some of the common uses of underpinning when it comes to soil-based issues include: stabilizing conditions prone to causing sinkholes, treating expansive or weakened soil, and strengthening foundations built on weak soil. 

WHEN IS UNDERPINNING NECESSARY?

Underpinning has various uses when it comes to securing your foundation.

Foundation Repair

One of the best and most easily recognizable ways to know if you need to consider underpinning to repair your foundation is if there are visible cracks. A structure with foundation cracks that are greater than ¼ inch - especially if they are diagonal cracks - is showing signs of a faulty foundation that could use underpinning as a repair. It can also be used for  raising uneven concrete foundations and slabs.

New Construction

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 Existing Structure

If you’re planning on adding more weight to a structure by making an addition or other renovations, you may need to reinforce your 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?

It’s not uncommon for your foundation to begin to settle due to unstable soil, underpinning methods help your foundation stay secure.

Some underpinning methods involve stabilizing your foundation by pouring concrete into excavated sections underneath your foundation.

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 PROCESS OF FOUNDATION UNDERPINNING?

The underpinning process begins with excavating soil beneath your home or building’s existing foundation in stages. These stages, or “pins,” are important to the process as they ensure the building’s current foundation isn’t undermined, preventing structural damage from taking place during the underpinning. 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, giving your structure a new lease on life.
