How much does foundation repair cost?
A waterproof crack repair like this, is $600-$800 and includes a lifetime warranty.
When push piers are required to address settlement, they start at $1700 each, and are needed every 6’-8’ along the damaged wall. (Watch as the foundation is lifted and the crack vanishes).
This project permanently corrected 2 degrees of inward lean on an 8” poured concrete wall. Combined with exterior waterproofing, sump pump, and a buried discharge line, it was a $24,000 project and $8,000 less than the other guy.
Here’s Calder, the owner, showing the guys how to “buck a pile.”

Common causes of foundation problems in St. Louis
St. Louis is known for its uniquely troublesome foundation conditions, thanks to widespread clay-rich soils that expand and contract with changing moisture levels and make foundation problems both common and persistent for homeowners across the region.
Expansive Clay Soil – Swells when wet, shrinks when dry, creating movement.
Heavy Rain & Flooding – Leads to water intrusion and erosion around your foundation.
Freeze-Thaw Cycles – Seasonal temperature changes stress concrete and masonry.
Poor Drainage – Directs water toward, instead of away from, your foundation.

Helical and push piles for foundation repair
A section of helical pile we install. They’re typically extended and screwed 20+’ into the earth.
Helical piles or push piles offer a permanent solution to foundation settlement problems.
These steel supports are driven deep into the ground until they reach stable, load-bearing soil. Helical piles, which resemble large screws, are twisted into the ground using hydraulic machinery, while push piles are driven in using hydraulic pressure. We install both, and will make a recommendation based on the specific use case.
Once installed, these piles provide a stable base for the foundation. The foundation can then be lifted and secured to the piles, preventing further settlement and stabilizing the structure.
Wall bow or wall lean
Wall bowing or leaning can be a serious structural issue that occurs when foundation walls start to curve inward or tilt.
When soil around the foundation becomes saturated with water, it expands and pushes against the wall. Other factors contributing to wall bowing include expansive soils, and frost heaving in cold climates.
Signs of wall bowing include visible curvature in the wall, cracks at the connections between internal and external walls, and gaps between internal finishes and the external wall.
The sooner an issue is identified, the better. Solutions may include installing wall anchors, steel beams, or carbon fiber strips to reinforce the wall, as well as improving drainage around the foundation to reduce hydrostatic pressure.
Stone and Concrete Foundations
Stone and concrete foundations can run into problems when water, dirt, and time take their toll. Water is a big troublemaker—it can sneak into tiny cracks in concrete or between stones, making the "glue" (mortar) weak and crumbly or causing the concrete to crack. Sometimes, bad rocks mixed into the concrete can even expand when they get wet, making the problem worse. Plus, dirt around the house pushes against the foundation when it’s wet and shrinks away when it’s dry, which can cause cracks and make walls bend or bulge.
Over time, these cracks can grow bigger, letting even more water in and making basements damp or leaky. If these problems aren’t fixed, they can weaken the foundation and cause serious damage to the house. To prevent this, it’s important to keep water away from the foundation, fix cracks early, and make sure the area around the foundation stays dry and in good shape. Taking care of small issues now can save big problems later!
