Stop Foundation Settlement
Foundation problems can affect the safety and stability of your entire home or building. When a foundation begins to shift or settle, it can lead to cracks in walls, uneven floors, and structural damage over time. Many property owners first notice small warning signs, but these issues can become more serious if they are not addressed early.
STL Polyjack provides foundation repair in St. Louis, MO to stabilize structures and correct foundation movement. Our team identifies the cause of the problem and provides repair solutions designed to restore support and prevent further damage. Addressing foundation issues early can help protect your property and avoid larger structural repairs in the future.
Why Foundations Shift or Settle
Foundations depend on stable soil for support. When the soil beneath the structure changes, the foundation can begin to move or settle.
Common causes include:
- Soil erosion caused by water around the foundation
- Expansive clay soils that shrink and swell with moisture changes
- Poor soil compaction during construction
- Drainage problems around the property
- Natural ground settlement over time
When the soil beneath the structure loses support, the foundation can begin to sink, tilt, or crack. Proper foundation repair focuses on stabilizing the structure and addressing the conditions that caused the movement.
Signs Your Foundation May Need Repair
Foundation movement often becomes noticeable through changes in the structure of the building.
You may need foundation repair if you notice:
- Cracks in foundation walls
- Interior wall cracks or ceiling cracks
- Uneven or sloping floors
- Doors or windows that stick or do not close properly
- Gaps forming between walls and floors
- Water entering the basement or crawl space
These warning signs can indicate that the foundation is shifting and should be evaluated by a professional.
Foundation issues are often connected to soil movement and water problems around the structure. Saint Louis Polyjack also provides basement waterproofing, commercial waterproofing, and injection grouting to help control water intrusion and stabilize soil conditions. In some cases, soil erosion beneath concrete surfaces may also require void filling to restore proper support.

Our Fix: Structural Foundation Repair
Saint Louis Polyjack provides foundation repair solutions designed to stabilize structures and address the underlying causes of movement. Instead of simply covering cracks, our goal is to restore structural stability and help prevent further damage.
Our repair process generally follows three key steps:
1. Inspect the Foundation
Our team evaluates the structure to identify signs of movement, cracking, and potential soil issues affecting the foundation.
2. Address Structural and Soil Issues
Depending on the situation, repairs may include stabilizing the soil, sealing cracks, or reinforcing structural areas to restore support.
3. Restore Stability and Protect the Structure
Once repairs are completed, the structure is stabilized to help prevent additional shifting or water intrusion.
Benefits of Professional Foundation Repair
Addressing foundation issues early can help prevent larger structural problems and costly repairs later.
Some of the key benefits include:
- Protecting the structural stability of the building
- Preventing further cracking or settlement
- Reducing water intrusion into basements or crawl spaces
- Improving the overall safety of the property
- Preserving property value
Foundation repair focuses on correcting the cause of the problem rather than simply covering visible damage.
