Foundation settlement and house movement can occur when a soil layer can't support the weight of the home.

Have you noticed cracks in your foundation walls, uneven floors, or sticking windows in your home? If these sound like problems you've experienced, you may have a sinking or settling foundation.

At Keystone Basement Systems, we fix foundation settlement issues by installing steel foundation piers. These piers will extend beneath the foundation, contacting strong supporting soils that will permanently stabilize your structure.

Keystone Basement Systems are your local experts for all types of foundation repair. Call us for a free foundation inspection and foundation settlement repair quote today! We serve Pittsburgh, Cranberry Township, McKeesport and many nearby areas in Western PA, Northern West Virginia, and Eastern Ohio.

Identifying foundation settlement issues

Signs of a settling foundation can be very subtle at first -- many homeowners can go months or even years before noticing a crack in their foundation. The long-term damage from foundation settlement, however, is ongoing and will lead to more severe foundation problems.

Repairing foundation settlement

At Keystone Basement Systems, we recommend installing foundation piers to stabilize, repair, and restore a foundation that's been damaged by issues related to foundation settlement and poor supporting soils.

There are several different types of foundation piers that are designed to address each kind of foundation problem. We install three different kinds of foundation piers: push piers, helical piers, and slab piers.

Foundation Push Piers

Push piers connect the foundation to strong, stable soil or bedrock. Foundation piers attach to the base of the foundation with special brackets and extend through settling and unstable soil layers, transferring the weight of your home to competent soils.

Foundation push piers are straight, steel piers that attach to your foundation and extend far below the structure to strong supporting soils. During the installation, a section of the foundation footing is exposed and cut to attach to each pier's bracket. This is possible year-round from either inside or outside of your foundation or structure.

Foundation brackets are secured to the footing, and tubular pier sections are hydraulically driven through each bracket. Pier sections continue to be driven downwards until the piers meet competent strata that can bear the weight of your home without compression.

When all push piers have been installed, they will work in unison to transfer the weight of the structure to the strong soils or bedrock below. If possible, the home is also lifted back to its original, level position.

Foundation Helical Piers

Like push piers, helical piers are attached to the foundation by mounting a bracket. Helical piers include rotating blades that are advanced (or "screwed") into the soil.

Foundation helical piers are straight, steel piers that have helical blades welded to each shaft. This installation is possible from either inside or outside of your foundation. These piers are driven into the soils underneath your foundation, then each pier is connected to the structure's foundation via a steel bracket.

During the installation, a section of the footing is exposed and cut for each bracket. Next, round-shaft helical piers are mechanically advanced into the soil. Once the helical pier has been advanced into the soil, a foundation bracket is secured to the footing.

When all helical piers have been installed, they will work in unison to transfer the weight of the structure to competent soil. If possible, the structure is also lifted back to a level position.

Slab Pier Systems

When the soil beneath a concrete slab shrinks or settles, the slab itself is also likely to settle, often cracking in the process. Slab piers restore stability by connecting the slab to competent soil at greater depth.

Foundation slab piers are straight steel piers that extend from stable soils deep below the structure to support brackets directly in contact with the underside of the slab. These piers are meant to support a settling concrete floor, and are not appropriate for foundation wall stabilization.

Slab piers are also inappropriate for repairing heaving foundations, where the floor is being lifted by expansive soils or frost heave.

During installation, a small hole is cored through the concrete floor. A slab bracket is assembled beneath the concrete slab, and steel tubes are hydraulically driven down through this bracket assembly.

When the slab piers have reached competent soils, the weight of the slab is transferred through the piers to load-bearing soils below. If possible, the slab is lifted back to level position.

At the end of the installation, grout is pumped under the slab to fill any voids, and all cored holes in the slab are restored with new concrete for a clean, professional look.
