Concrete Crack Repair in the San Antonio Area
Learn how to repair cracks in concrete surfaces like patios, driveways, pool decks, and more.
Concrete is a strong and durable material, but even when it’s installed well, it can eventually crack. Rather than replacing an entire surface, repairing or resurfacing the concrete is often more affordable and efficient.

Cracks in concrete can occur for several reasons. Incorrect installation, such as an improper water mix or not using control joints, can cause cracking. However, even perfectly installed concrete can crack due to its inherent limitations. While concrete has excellent compressive strength (withstanding heavy loads), its tensile strength (resistance to bending or stretching) is lower, which makes it susceptible to cracks.

TYPES OF CONCRETE CRACKS
Different cracks require unique repair approaches, depending on the underlying cause and severity. Below are some common types of cracks and how they’re typically addressed:
Hairline cracks
These small cracks are often the result of natural shrinkage as the concrete cures. While they usually don’t indicate structural issues, they still need attention to prevent moisture from seeping in, which can worsen the crack over time.
Solution: Hairline cracks are usually filled with crack filler or adhesive to stop further moisture penetration.
Shrinkage cracks
Wider than hairline cracks, these form when the concrete dries too quickly or when too much water is used in the mix. They tend to appear in random patterns.
Solution: Filling shrinkage cracks can often halt their progression. For more significant cases, resurfacing may be required.
Settlement cracks
These appear when the ground beneath the concrete isn’t properly compacted, or when heavy loads are applied before the concrete fully cures. These cracks are usually wider and may be accompanied by unevenness in the slab.
Solution: Minor settlement cracks can sometimes be fixed through grinding and sealing. In more serious cases, resurfacing or replacement may be necessary.
Structural cracks
These are the most serious type, often caused by poor reinforcement or shifting foundations. Structural cracks are typically wider and deeper than other types.
Solution: Significant repairs or reinforcement are often needed for structural cracks. In some cases, replacing the slab may be the most cost-effective option.
UNDERSTANDING THE CAUSE OF CONCRETE CRACKS
Identifying the reason for cracks is essential for preventing future problems. Whether caused by environmental factors (like moisture or freeze-thaw cycles) or poor installation, different repair methods are required. For example, cracks resulting from corrosion of steel reinforcement may need more than a surface repair. A professional contractor can assess the issue and suggest the most appropriate solution.
OPTIONS FOR REPAIRING CRACKED CONCRETE
Here are a few techniques our contractors use to repair cracked concrete:
- Custom Scoreline Effect: Developed by SUNDEK, this method integrates existing cracks into the design of the surface, turning them into functional expansion joints. We enhance the appearance of these cracks to complement the design of the slab.
- Repair the crack: In this option, we repair each crack individually. Afterward, you may choose to resurface the entire slab to create a uniform look.
- Remove and replace: For severe cracks, repair might not be a viable long-term solution. If this is the case, having a professional from SUNDEK assess your surface and recommend replacement options is a good idea.
RESURFACING: A SUSTAINABLE ALTERNATIVE
If the concrete is still in good condition structurally, resurfacing provides a simpler, eco-friendly option. Instead of tearing out the existing slab, a contractor preps the surface and adds a new layer of material. This approach conserves resources, reduces labor, and minimizes waste.
COST OF CONCRETE CRACK REPAIR
The cost of repairing cracks varies depending on the size and extent of the damage, and how you choose to address it. Small hairline cracks can often be repaired with inexpensive crack fillers. However, for more extensive damage, it’s best to consult a professional.
CAN I REPAIR CONCRETE CRACKS MYSELF?
While minor cracks can be fixed by homeowners, it’s crucial to understand that proper materials and techniques are required for a lasting repair. Correct product mixing and drying conditions are key. Incorrectly done, the crack can return or even worsen. Hiring an experienced contractor ensures a proper and durable repair.
