Concrete surfaces, whether driveways, patios, or foundations, are prone to cracking over time due to various factors such as weather conditions, soil movement, and wear and tear. While some cracks are minor and can be addressed with DIY methods, others require the expertise of a professional contractor. Understanding the difference is crucial to maintaining the integrity and safety of your property.
Identifying the Type of Crack
The first step in determining whether to tackle a crack yourself or hire a professional is to identify the type and severity of the crack:
Hairline Cracks
These are thin, superficial cracks often less than 1/8 inch wide. They typically result from concrete shrinkage during curing or minor settling. Hairline cracks are usually cosmetic and can be repaired using DIY methods.
Structural Cracks
Wider cracks, especially those greater than 1/4 inch, or cracks that extend through the depth of the concrete, may indicate structural issues. These cracks can result from significant settling, soil movement, or heavy loads and often require professional assessment and repair.
DIY Repair: When Is It Appropriate?
DIY repairs are suitable for minor, non-structural cracks. Here’s how to approach such repairs:
Materials Needed
- Concrete crack filler or sealant
- Wire brush
- Chisel
- Protective gloves and eyewear
Repair Steps
- Clean the Crack: Use a wire brush to remove debris and loose material from the crack.
- Widen the Crack: For better adhesion, widen the crack slightly using a chisel.
- Apply Sealant: Fill the crack with a concrete crack filler or sealant, following the manufacturer’s instructions.
- Allow to Cure: Let the repair material cure as directed before applying any load or finishing touches.
While DIY repairs can be cost-effective, they may not provide a permanent solution, especially if underlying issues are not addressed.
When to Call a Professional Contractor
Certain situations warrant the expertise of a professional:
Structural Concerns
Cracks accompanied by signs like uneven floors, sticking doors or windows, or noticeable shifts in the structure indicate potential foundation problems. Professional contractors can assess and address these issues comprehensively.
Extensive Damage
If the concrete surface has multiple cracks, significant spalling, or has shifted, professional intervention is necessary to restore structural integrity.
Specialized Repair Methods
Some repair techniques, such as polyurethane foam injections or piering, require specialized equipment and expertise that professionals possess.
Benefits of Hiring a Professional
Engaging a professional contractor offers several advantages:
- Accurate Assessment: Professionals can identify the root cause of the cracking and recommend appropriate solutions.
- Durable Repairs: With access to high-quality materials and advanced techniques, professionals provide long-lasting repairs.
- Safety Assurance: Proper repair of structural cracks ensures the safety and stability of your property.
Conclusion: Making the Right Choice
