Common Causes of Basement Floor Cracks
Understanding the root cause of basement floor cracks is essential for effective repair. Here are some of the most common causes:
Soil Settlement
As soil beneath your home naturally settles, it can create voids under the concrete slab, leading to cracks and an uneven surface.
Hydrostatic Pressure
Excess moisture around the foundation can cause pressure against the basement floor, leading to cracks and potential water infiltration.
Shrinkage Cracks
During the curing process, concrete may shrink, resulting in minor cracks. While not always a structural concern, they can widen over time and allow moisture to seep in.
Foundation Shifting
If your home’s foundation shifts due to poor soil conditions, excessive moisture, or tree roots, your basement floor may crack or become uneven.
Poor Construction Practices
Improperly mixed concrete, insufficient reinforcement, or inadequate curing times can all contribute to basement floor cracking and leveling issues.
Our Basement Floor Crack Repair & Leveling Process
At Cornerstone Structural Repair & Waterproofing, we utilize advanced techniques and high-quality materials to ensure durable, effective repairs. Our concrete crack repair process includes:
1. Crack Inspection & Assessment
We conduct a thorough assessment to determine the extent of the damage and identify the underlying cause for all foundation cracks.
2. Concrete Crack Repair
Depending on the severity of the cracks, we use the following repair techniques:
- Epoxy Injection – A strong, waterproof solution that bonds cracks to restore concrete integrity.
- Polyurethane Foam Injection – Ideal for sealing active leaks and preventing future moisture infiltration.
3. Basement Floor Leveling Solutions
If your basement floor is uneven, we offer effective leveling methods, including:
- Mudjacking (Slabjacking) – A cost-effective way to lift and stabilize sunken concrete by injecting a cement-based slurry underneath.
- Polyurethane Foam Leveling – A modern alternative that provides a lightweight, durable, and moisture-resistant lift.
4. Surface Resurfacing & Sealing
Once cracks are repaired and the floor is leveled, we apply a protective sealant or resurfacing treatment to enhance durability and prevent future damage.
