Concrete is a durable material, but it’s not immune to cracking. Fortunately, when cracks appear, you don’t need to replace the entire slab. In many cases, concrete repair and resurfacing offers a more efficient and cost-effective solution.

However, even perfectly installed concrete may develop cracks due to environmental factors. While it can bear heavy loads, concrete doesn’t flex well and can crack when subjected to tension or bending forces. Additionally, freeze-thaw cycles can cause significant stress that leads to cracks.
Different cracks require different repair strategies. Before proceeding with a repair, it’s essential to identify the type and severity of the crack. Below are the most common types and how to address them:
These are typically caused by the natural shrinkage of concrete as it cures. While they don’t indicate a structural problem, they should be repaired to prevent water infiltration. Red more in this post: Should you fix hairline cracks in your pool deck?.
Repair solution: Use crack filler or adhesive to seal the crack.
Wider than hairline cracks, these appear in irregular patterns and are usually caused by the concrete drying too quickly or an improper water mix.
Repair solution: Fill with crack filler or adhesive to stop them from spreading. In some cases, concrete resurfacing may be required for larger cracks.
These cracks form when the ground beneath the slab isn’t compacted correctly or when weight is applied before the concrete is fully cured. They are often accompanied by uneven surfaces.
Repair solution: Minor settlement cracks can be addressed through grinding and sealing, while more severe cases might require resurfacing or replacement.
The most concerning type of crack, these are deeper and wider than others. Structural cracks usually result from inadequate reinforcement or foundation shifting.
Repair solution: For significant structural cracks, replacing the slab may be the best long-term fix.
It’s crucial to determine why your concrete is cracking before making repairs, as this helps prevent future damage. Environmental factors (like moisture and freeze-thaw cycles), external elements (such as tree roots growing underneath), or poor installation practices can all contribute to cracking. If the issue stems from poor reinforcement, surface repairs alone won’t be enough. A professional contractor can assess the problem and recommend the appropriate solution.
At SUNDEK of Houston, we use a variety of methods to repair cracked concrete, depending on the type and severity of the crack:
If your concrete slab is still in good structural condition, resurfacing is often a better alternative to a complete replacement. It eliminates the hassle of demolition and disposal, while also being a more environmentally friendly option. Resurfacing allows you to reuse the existing slab and give it a fresh, updated look.
For small hairline cracks, using an affordable crack filler may be sufficient. However, larger cracks or more extensive damage will require a professional assessment. SUNDEK of Houston can evaluate the damage and recommend the best repair options tailored to your needs.
DIY repair is feasible for minor cracks, but proper research and quality products are essential for ensuring a lasting result. Incorrect repairs can worsen the problem or lead to recurring cracks. To ensure a long-lasting, professional-grade repair, it’s wise to hire an experienced contractor.
