Concrete crack repair ranges from simple caulk-style sealing of hairline cracks to routing and filling wider structural cracks with epoxy or polyurethane injection. The process typically involves cleaning the crack, routing it to a uniform width if needed, applying a bonding primer, filling with the appropriate sealant or repair material, and finishing flush with the surrounding surface. In NorCal, thermal expansion, soil movement, and tree roots are the primary causes of concrete cracking.

Concrete Crack Repair en San Rafael — Preguntas Frecuentes

Are concrete cracks serious?+

Hairline cracks (under 1/8 inch) are usually cosmetic. Cracks wider than 1/4 inch, growing cracks, or cracks with vertical offset may indicate structural issues requiring professional assessment.

What causes concrete to crack?+

Common causes include shrinkage during curing, thermal expansion/contraction, soil settlement, tree root pressure, heavy loads, and inadequate control joints.

Can I repair concrete cracks myself?+

Small hairline cracks can be DIY-sealed with concrete caulk. For structural cracks, epoxy injection, or cracks in foundations, professional repair is recommended.

Will repaired cracks be visible?+

Repair material will be visible but can be color-matched. For a uniform appearance, consider resurfacing the entire slab after crack repairs.
