Red Flags You Can See the Same Day

    Poor drainage/slope: Water ponds against the house or in low spots. Slabs should shed water—typically 1/8–1/4" per foot. Jagged edges & sloppy forms: Wavy edges, bulged forms, or honeycombing at margins suggest rushed forming and poor consolidation. Overworked surface: Dark, blotchy, or burnished areas from finishing with bleed water present—expect delamination and scaling later. Missing curing: No curing compound or cover means a chalky surface within days during KC’s windy season.

Issues That Appear Within Weeks

    Random cracks: Long, jagged cracks not aligned with joints indicate late or missing saw cuts, or too-wide joint spacing. Map cracking/crazing: Fine surface networks often tied to rapid drying, over-troweling, or water added during finish. Color inconsistency: Patchy, zebra-striping panels reveal poor curing, mixed finishing timing, or mismatched batches.

Winter Tells in KC

    Edge spalling: Downspouts discharging on slab margins cause saturated edges that pop and flake in freeze–thaw cycles. Scaling/flake-off: Non air-entrained mixes or no curing often show widespread paste loss after a deicer-heavy season.

What Quality Looks Like

    Base and forms: Compacted granular base, geotextile where needed, tight forms staked and braced. Rebar on chairs: Steel tied and supported—not lying in dirt—with dowels at thresholds and cold joints. Straight joints: Spacing matched to thickness (≈ 24–30×), clean cuts, and consistent depth. Uniform finish: Even broom texture, crisp edges, no tears, no bleed water sheen. Curing & cleanup: Curing compound applied promptly; site left neat with joint dust managed.

Questions to Ask Before Final Payment

    “Please walk me through your joint layout and cut timing.” “Which curing method did you use, and when was it applied?” “Is the mix air-entrained for exterior exposure in KC?” “How did you verify base compaction?”
