Concrete is a durable and versatile material widely used in driveways, patios, and foundations across St. Louis. However, exposure to extreme weather conditions, soil movement, and regular wear and tear can cause cracks over time. If left unaddressed, these cracks can lead to structural problems, water infiltration, and costly repairs. In this blog, we’ll explore the causes of concrete cracks, effective repair methods, and professional solutions available in St. Louis to restore and extend the life of your concrete surfaces.
Understanding Concrete Cracks
Concrete cracking is a common issue, but not all cracks are the same. Identifying the type of crack is crucial in determining the best repair method.
Types of Concrete Cracks
- Hairline Cracks – These are minor surface cracks often caused by shrinkage as the concrete dries. While they don’t pose structural threats, they can allow moisture penetration, leading to further damage over time.
- Settlement Cracks – These occur when the soil beneath the concrete shifts or compacts, causing uneven settling. They are commonly seen in driveways and foundations.
- Expansion Cracks – Extreme temperature fluctuations in St. Louis can cause concrete to expand and contract, leading to cracking. Expansion joints are designed to minimize this, but improper installation can result in damage.
- Structural Cracks – Large, deep cracks that continue to widen over time indicate serious underlying structural problems. These require professional intervention.
- Frost Heave Cracks – St. Louis experiences freezing temperatures, which can cause water beneath the concrete to freeze and expand, lifting the concrete and causing cracks.
DIY Concrete Crack Repair Methods
For minor cracks, homeowners can attempt DIY repairs to prevent further damage. Here are some common solutions:
1. Using Concrete Crack Sealant
For hairline cracks and minor surface damage, applying a high-quality concrete crack sealant is an easy fix. Clean the crack thoroughly, remove debris, and apply the sealant using a caulking gun. This method prevents moisture intrusion and protects against further expansion.
2. Patching with Concrete Resurfacer
For shallow cracks in patios and driveways, a concrete resurfacer can restore a smooth finish. This involves cleaning the area, mixing the resurfacer, and applying it over the cracks with a trowel.
3. Epoxy Injection for Structural Cracks
Epoxy injections provide a strong bond for deep cracks, particularly in foundations. This method requires specialized tools to inject the epoxy into the crack, ensuring structural integrity is restored.
4. Polymer-Based Crack Filler
For flexible repair solutions, polymer-based fillers work well for cracks that may continue to expand or contract due to temperature changes. They remain pliable, preventing future damage.
Professional St. Louis Concrete Crack Repair Solutions
While DIY solutions work for minor cracks, professional services are necessary for major structural damage or long-term durability. Here are the best professional methods available in St. Louis:
1. Polyurethane Foam Injection
This modern repair method is highly effective for sealing foundation cracks. Polyurethane foam expands to fill the crack completely, providing waterproofing and structural reinforcement. It’s ideal for preventing water leakage in basements and foundations.
2. Mudjacking for Uneven Concrete
If your driveway or patio has sunk due to soil shifting, mudjacking (or slab jacking) is a cost-effective solution. This involves pumping a slurry mixture under the concrete slab to lift and level it, reducing the risk of further cracking.
3. Polyjacking for a Long-Term Fix
Similar to mudjacking, polyjacking uses a high-density polyurethane foam instead of a mud slurry. This method provides a more durable and long-lasting solution to lift and stabilize concrete slabs.
4. Concrete Resurfacing and Overlaying
For widespread cracks and surface deterioration, resurfacing or overlaying is an excellent option. Professionals apply a new layer of concrete or a polymer-based overlay, restoring the appearance and functionality of patios, driveways, and foundations.
5. Stamped Concrete Restoration
If you have decorative or stamped concrete that’s cracked, repair specialists can match textures and colors to restore the original design seamlessly.
6. Carbon Fiber Reinforcement
For severe structural cracks in foundations, carbon fiber strips can be installed to reinforce the concrete and prevent further movement. This method is effective in stabilizing foundation walls against pressure from surrounding soil.

- Use Expansion Joints – These allow for natural expansion and contraction, preventing stress cracks.
- Avoid Heavy Loads – Excessive weight can cause driveways and patios to crack over time.
- Address Soil Issues – Stabilizing the soil before pouring concrete helps prevent settlement cracks.
