United Structural Systems: Types of Foundation Repair

United Structural Systems and Foundation Repair Methods

United Structural Systems evaluates foundation damage and selects repair techniques based on soil conditions, structure type and severity of movement. The company commonly installs helical piers, push piers, slab jacking, wall anchors and carbon fiber reinforcement to stabilize or lift settling foundations. Each method targets a specific failure pattern, and a qualified inspection is the starting point for choosing the right approach.

Helical Piers

How They Work

Helical piers are steel shafts with bearing plates welded to them. A hydraulic drive system rotates the pier into the ground until it reaches load-bearing soil or bedrock. The foundation is then secured to the pier with a bracket, and the weight of the structure helps hold it in place.

When United Structural Systems Uses Them

Helical piers suit light- to medium-load residential foundations and are often selected when access limits heavy equipment. They work in a range of soil types and are useful for new construction as well as repair projects where minimal vibration is required.

Push Piers

How They Work

Push piers are steel tubes driven hydraulically into competent soil or bedrock beneath a foundation. Once in place, the system uses the building's weight as resistance to transfer the load to stable strata. A grout or epoxy bond can be created at the footing connection to lock the lift in place.

When United Structural Systems Uses Them

Push piers are a common choice for heavy residential and commercial structures with deep settlement. They are installed from outside the home or through existing footings and are effective where soil conditions vary widely across a site.

Slab Jacking

How It Works

Slab jacking injects a cementitious or polyurethane grout mixture beneath a concrete slab through small drilled holes. The material expands or fills voids, raising the slab back toward its original position and reducing cracking or uneven surfaces.

When United Structural Systems Uses Them

Slab jacking is often selected for interior slabs, patios, walkways and pool decks where the settlement is moderate and the soil beneath can be stabilized. It is typically faster and less disruptive than full pier-and-beam replacement.

Wall Anchors and Carbon Fiber Reinforcement

Wall Anchors

Wall anchors are installed through basement or crawlspace walls into stable soil outside the foundation. A steel plate on the interior is connected to an anchor rod, and tightening the rod applies tension that resists further inward movement of the wall.

Carbon Fiber Reinforcement

Carbon fiber strips or fabrics are bonded to foundation walls with epoxy to add tensile strength. This method is used for walls that are bowed or cracking but still within a repairable range, avoiding the need for full wall replacement.

When United Structural Systems Uses Them

Anchors are suited to basements experiencing lateral pressure from expansive or saturated soils. Carbon fiber reinforcement works well for moderate deflection and is often chosen when interior space must remain unobstructed.

Choosing the Right Method

United Structural Systems bases the selection on several factors:

• Soil type and load-bearing capacity
• Depth and pattern of foundation settlement
• Structure weight and type (slab, pier and beam, basement)
• Access constraints and interior finish preservation
• Budget and long-term warranty goals

What a Typical Repair Looks Like

United Structural Systems starts with a free inspection and may use level surveys, moisture readings and soil analysis to diagnose the cause of movement. After a written proposal, installation typically takes one to three days, followed by a warranty-backed inspection to confirm stability. The company documents before-and-after conditions and provides maintenance guidance to help homeowners protect the repair over time.
