Concrete Repair & Replacement in Independence, MO

Independence is in the middle of a generational concrete replacement cycle. Residential flatwork installed during the city's mid-century development boom — driveways, patios, sidewalks, and steps poured from the 1940s through the 1970s — is now 40 to 70 years old and failing in large numbers. Jackson County clay has been working against the subgrade beneath these slabs for decades, causing base failures that surface as heaving, cracking, and panel separation. The repair-versus-replace question is answered by base condition: if the subgrade and base have failed, repair of the surface is a short-term measure that will not hold.

Near the Independence Square and in the Fairmount neighborhood, we diagnose repair situations on a routine basis. A common scenario: a homeowner has had cracks filled by a previous contractor, the cracks have reopened or new ones have formed nearby, and the slab face has begun spalling at the filled locations. The cracks reopened because the base movement that caused them was never corrected. At this point, crack filling is no longer productive — the slab needs to come out and the subgrade needs to be addressed before a new pour goes in.

Our repair diagnostic process starts with a site walk and a physical assessment of the slab — tapping for hollow spots, checking panel elevation relative to adjacent panels, looking at crack pattern and width. Tight hairline cracks in a slab with a stable base can be routed and sealed to prevent water infiltration. Structural cracks with differential movement, hollow-sounding panels, or heaved edges indicate base failure. We do not recommend resurfacing or overlay on slabs with failing bases — the overlay will debond within a season as the base continues to move.
