Foundation Wall Repair

Foundation wall repair

Our foundation wall repair solutions fix bowing, leaning, and cracked walls.

Your foundation walls are critical to your home's overall stability. Over time, various factors, such as soil movement, water intrusion, or poor construction, can cause your foundation walls to bow, crack, or lean. If left unaddressed, these issues can lead to severe structural damage.

Signs that you might need foundation wall repair can include:

  • Bowing walls
  • Cracking or leaning walls
  • Horizontal, vertical, or stair-step cracks

Our Wall Repair Methods

We offer a range of foundation wall repair solutions, including:

Wall Anchors

We can install wall anchors to help stabilize bowed and cracked walls affected by hydrostatic pressure. Wall anchors require minimal excavation and can usually be installed in a single day, unlike more invasive methods, such as complete wall replacement. The wall anchors we install are covered by a 25-year manufacturer's warranty.

Helical Tiebacks

Designed to strengthen basement or retaining walls, helical wall tiebacks provide support by attaching to the foundation walls and anchoring into deep, stable soil.


Foundation Settlement Repair

Foundation settlement repair

Our foundation pier systems safely lift and restore the stability of your home.

If your foundation is settling, sinking, or showing signs of unevenness, it could be due to soil movement beneath your home. Moisture changes, poor compaction, or weak soil often cause foundation settlement.

Signs that you might need foundation piers can include:

  • Settling or sinking foundation
  • Uneven floors
  • Cracks in walls or floors

Our Settlement Repair Methods

We provide two main types of solutions for fixing foundation problems: push piers and helical piers. Which one you need depends on your soil type and how serious your foundation issues are. Push piers are great for fixing problems when the foundation is shallow and the soil can handle a lot of weight. If your foundation issues are deeper, and the soil isn't as strong, helical piers are the better choice. Our professionals can inspect your foundation and recommend the best solution for your situation.

Helical Piers

We use a patented helical pier system to permanently stabilize foundations by mechanically "drilling" the helical piers, also called helical piles, through the shifting soil to a stable, load-bearing strata. Our helical piers are covered by an industry-leading 25-year warranty.

Push Piers

An effective solution for settling foundations, steel push piers are driven deep into the soil to lift and support weak foundations. We use American-made steel piers covered by a 25-year warranty from the manufacturer.


Foundation Crack Repair

Our foundation crack repair services stop leaks and pests while preventing further foundation damage.

Foundation cracks are usually a symptom of foundation settlement or bowing. Cracks in your foundation can lead to water infiltration, pest issues, and further structural damage. Whether the cracks are vertical, horizontal, or stair-step, it is important to address them before they worsen.

There are three primary types of foundation cracks to look for:

  • Vertical Cracks: Often caused by settling or shrinkage.
  • Horizontal Cracks: Typically due to wall pressure from soil expansion.
  • Stair-step Cracks: Often appear in brick or block foundations due to settlement or shifting.

Our Crack Repair Method

Crack injection is a common method used to repair foundation cracks, but its effectiveness depends on the severity and type of crack. If the crack is caused by structural damage or water damage, crack injection may not address the underlying issue. Instead, we use long-lasting solutions to support foundations and prevent further settlement and cracking. Depending on the cause of the foundation cracks, we might use underpinning, wall anchors, helical tiebacks, or a combination of these structural repair solutions to ensure that your foundation remains strong and stable.


Slab Repair

Foundation wall repair

We offer reliable solutions to lift and support sinking foundation slabs.

Due to soil movement, moisture changes, or poor compaction, slab foundations can suffer from settlement, cracking, or uneven floors. If not addressed, these issues can affect the overall structural integrity of your home.

Signs that you might need slab repair can include:

  • Cracking and settling floors
  • Uneven floors or noticeable dips
  • Gaps around windows and doors

Our Slab Repair Methods

Slab Piers

We can install helical piers and push piers to effectively lift and support a sunken slab. We install high-performance slab piers covered by a 25-year manufacturer's warranty.

Advantages of our slab piers:

  • Strength and stability: Our slab piers are built to hold heavy structures securely, helping to prevent sinking or settling by transferring weight to strong soil layers deep underground.
  • Versatility: They can be adjusted to work with different types of soil and foundations, making them suitable for many different buildings and situations.
  • Minimal disruption: The installation process uses small, portable equipment that vibrates very little, so it causes minimal disturbance to the area around it.
  • Precise lifting: Adjustable brackets allow for careful leveling and lifting of the slab, helping to fix uneven surfaces and close up cracks.
  • Field load testing: Each pier can be tested on-site to verify its capacity to support the structure's load, providing peace of mind.
  • Cost-effective: Installing slab piers can be a cost-effective way to repair foundations, preventing further damage and increasing the value of the property.

Crawl Space Structural Repair

Our crawl space support jacks quickly and effectively lift sagging floors back into position.

Excess moisture in crawl spaces can lead to issues such as sagging floors and structural damage. When moisture levels are too high, support beams and joists can rot, ultimately weakening the building's structure. Additionally, if the supports are spaced too far apart or the ground underneath isn't stable, it can lead to settling and uneven weight across the floor above. Issues like poor drainage, high humidity, and not properly sealing the crawl space can make these problems even worse.

Signs that you might need crawl space structural repair can include:

  • Excess moisture or humidity
  • Sagging floor joists or beams
  • Mold growth or rotting wood

Our Crawl Space Structural Repair Method

Crawl Space Support Jack System

The patented SmartJack® system provides immediate support to sagging floors above crawl spaces and helps eliminate the bouncing or squeaking caused by inadequate support. The supplemental supports can be installed where existing column supports have failed or settled. The SmartJack system is backed by a 25-year warranty against manufacturing defects.

Benefits of the SmartJack® System:

  • Immediate lifting of sagging floors back to their original position
  • Adjustable support accommodates future settling
  • Corrosion-resistant materials ensures longevity
  • Cost-effective option to address problems caused by undersized joists or girders or incorrect joist spacing
  • Galvanized steel components resist rust and corrosion
