Although concrete is known for its durability, it’s still prone to cracking. Fortunately, when cracks appear, replacing the entire surface isn’t necessary. Repairs and concrete resurfacing often provide a more efficient and cost-effective solution.

Even well-installed concrete can develop cracks due to environmental conditions. While concrete is strong, it doesn’t handle tension or bending well, making it susceptible to cracking under stress. Freeze-thaw cycles can also exert pressure that leads to cracks.
The method of repair depends on the type of crack. Before proceeding, it’s crucial to assess the crack's type and severity. Here are common types of cracks and ways to address them:
These small cracks occur due to natural shrinkage as concrete cures. Although they don’t typically indicate structural issues, they should be repaired to prevent water from seeping in.
Repair tip: Apply crack filler or adhesive to seal the crack.
Larger than hairline cracks, these often appear in irregular patterns and result from rapid drying or an improper water mix.
Repair tip: Use crack filler or adhesive to stop further spreading. Resurfacing may be needed for larger cracks.
Settlement cracks happen when the ground beneath the slab isn’t compacted properly or if weight is applied before the concrete has fully cured, often creating uneven surfaces.
Repair tip: Minor settlement cracks can be fixed by grinding and sealing. Larger cracks may require resurfacing or replacement.
These are the most serious, typically deep and wide, and often result from poor reinforcement or shifting foundations.
Repair tip: For severe structural cracks, replacing the slab may be the most effective long-term solution.
It’s important to determine the root cause of your concrete cracks before starting repairs so you can help prevent future damage. Cracks can result from environmental factors like moisture and freeze-thaw cycles, poor installation, or external issues like tree roots. If the issue is due to inadequate reinforcement, surface repairs alone won’t suffice. A professional contractor can assess the problem and recommend the appropriate solution.

If your concrete slab is structurally sound, resurfacing is a greener alternative to full replacement. It avoids the labor and cost of demolition while also avoiding having to dispose of the old material. Resurfacing reuses the existing slab but gives it a fresh, updated appearance.
Repair costs vary depending on the crack's size and severity. Minor hairline cracks can often be fixed with an inexpensive crack filler. Larger or more extensive damage requires a professional assessment. SUNDEK of Nashville can evaluate the damage and recommend the most suitable repair method for your needs.
DIY repair is possible for smaller cracks, but it’s important to use quality products and follow the right procedures to ensure long-lasting results. Poorly executed repairs can make the issue worse or lead to recurring cracks. For a durable, professional finish, it’s best to consult an experienced contractor.
