About Crack Repair and Joint Filling
Concrete crack repair and joint maintenance are critical for preserving commercial concrete investments. Untreated cracks and failed joints accelerate deterioration, create safety hazards, and diminish property appearance. Timely repair extends concrete life and prevents costly replacement.
Crack repair techniques vary based on crack type, width, and cause. Hairline cracks may only need sealing to prevent water intrusion. Wider structural cracks may require routing and sealing, epoxy injection, or polyurethane foam injection depending on the situation.
Joint maintenance addresses the expansion and contraction joints that control concrete cracking. Joints require periodic resealing as sealant materials age and fail. Failed joints allow water infiltration that damages subgrade and accelerates concrete deterioration.
Commercial concrete maintenance programs should include regular joint and crack assessment with timely repairs. We work with property managers to develop maintenance programs that protect concrete investments and minimize life-cycle costs.

Frequently Asked Questions
How do you determine the right repair method for cracks?
Repair method depends on crack cause, width, depth, and whether cracks are active or dormant. We assess cracks to understand their cause before selecting repair methods. Active cracks require flexible sealants; dormant cracks can be filled with rigid materials.
Can crack repair prevent further cracking?
Repair cannot prevent new cracks from forming, but proper repair of existing cracks prevents them from worsening and stops water intrusion that accelerates deterioration. Addressing root causes may prevent new crack formation.
How often should concrete joints be resealed?
Joint sealant life varies with material type and traffic, typically 5-10 years. We recommend annual inspection of joints with resealing as needed. High-traffic areas may need more frequent maintenance.
What materials do you use for joint filling?
We use various joint sealants depending on the application: silicone for high-movement joints, polyurea for quick-return-to-service, and polyurethane for general use. Material selection considers traffic, movement, and service requirements.
Can you repair cracks to restore appearance?
We can improve appearance significantly, but repairs are usually visible on close inspection. Color-matched repair materials minimize visual contrast. For highly visible areas, we discuss appearance expectations before proceeding.
