Helical Tiebacks for Foundation Repair

The primary cause of bowing or shifting walls is hydrostatic pressure, which is the force exerted by water-saturated soil against your foundation. Because there is nothing on the interior to counter that force, the wall begins to move. If left untreated, the wall can continue to move inward and eventually may collapse.

Poor drainage, clay-heavy soil, and repeated freeze-thaw cycles can all contribute to this pressure. Look out for these critical warning signs:

• Horizontal or diagonal cracks in your basement walls.

• Walls that are visibly leaning or bowing inward.

• Doors or windows that stick or are difficult to open and close, which can indicate a shifting foundation.

Bowing walls are most often seen in foundation walls constructed with concrete blocks. These concrete blocks are held together with mortar, and the mortar (unless it is reinforced), is the weakest spot. This is where you are most likely to see the failure. The walls are strongest at the corners, so the bowing is typically found toward the middle – in the form of stair-step foundation cracks.

• Installed From Inside – Minimal Yard Disruption
  Anchors are driven from inside your basement into undisturbed soil outside. No large digging means your landscaping stays intact.

• High-Strength Steel Reinforcement
  Steel rods connect interior wall plates to buried exterior anchor plates. These apply a counterforce to halt and reverse wall movement.

• Adjustable Torque System
  Over time—and during dry conditions—we can gradually tighten the system to straighten bowed or shearing walls and return them closer to their original position.

• Engineered for Precision and Durability
  Includes anti-kink hardware, torque-limiting controls, and custom brackets to prevent overcorrection and reduce stress on your foundation walls.

Reverse Wall Anchors for Outward-Tipping Walls

In some cases, especially with frost-protected foundations or walk-out basements, walls may lean outward. For these situations, we install a Reverse Wall Anchor System:

• Anchors are installed from the outside and pulled inward
• Exterior soil is excavated, and steel rods are inserted through the wall
• Interior wall plates apply force to bring the wall back into alignment
• If needed, minor slab excavation is done to help realign the foundation wall

This method is ideal for foundation wall straightening where walls have tipped or suffered block shear failure.

Our RockSolid™ Helical Anchor Systems Work For:

• Bowed Wall Repair
• Shearing Wall Repair
• Concrete Block Wall Repair
• Basement Wall Reinforcement
• Foundation Stabilization and Straightening
• Block Wall Repair and Concrete Wall Repair

Every home is different. We tailor our approach based on wall type (block, poured concrete), soil conditions, and the extent of movement.

Helical anchors offer numerous advantages over traditional repair methods:

• Minimal Disruption: The installation process is quick and requires little heavy equipment, meaning your yard and landscaping are minimally disturbed.
• Versatility: They can be used in a wide variety of soil and weather conditions, making them a flexible repair solution.
• Precision and Durability: The system is engineered for accuracy and is adjustable, ensuring a precise and long-lasting repair.
• Ideal for Tight Spaces: They are an excellent solution for structures in hard-to-access areas where larger equipment cannot operate.

Ignoring a bowing or cracked foundation can lead to a domino effect of structural problems. A minor crack can grow into a major structural failure, compromising the safety and value of your home. The longer you wait, the more extensive and expensive the repairs can become. Acting quickly can prevent further damage and ensure your home’s long-term stability.

The cost of helical anchor repair can vary significantly based on a number of factors. While a professional inspection is the only way to get a precise quote, understanding these key variables can help you estimate the potential investment.

While a professional inspection is the only way to get a precise quote, understanding these key variables can help you estimate the potential investment.

Here are the primary factors that affect the cost of helical anchor repair:

• Extent and Severity of Damage: This is the most significant factor. The worse the foundation damage, the more helical anchors will be needed to stabilize it. A small section of a bowing wall may only require a few anchors, while a severely settled or cracked foundation could require a much larger number, dramatically increasing material and labor costs.
• Soil Conditions: The type of soil on your property directly impacts the required depth and length of the anchors. For example, unstable or soft soil may require the anchors to be driven deeper to reach a stable, load-bearing stratum, increasing the overall cost. Rocky or dense soil can make the installation more difficult and time-consuming.
• Accessibility: How easy it is for the crew and equipment to access the repair area plays a major role. Obstacles such as decks, patios, mature landscaping, or narrow side yards can complicate the installation, potentially requiring more manual labor and specialized, smaller equipment.
• Installation Depth: The deeper the helical anchors must be driven into the ground to find stable soil, the more they will cost. Many companies charge a base price per pier up to a standard depth, with an additional cost for every extra foot of depth required.
