Form removal The process of stripping away the temporary wooden or metal forms after the poured concrete has cured and gained self-supporting strength.
Removing the forms too early can ruin a brand-new sidewalk, causing the edges to slough off or crack. NYC contractors typically perform form removal 24 to 48 hours after pouring, depending on the weather and concrete mix. Once the forms are pulled, the exposed gaps along the lawns or soil must be promptly backfilled to prevent trip hazards.

Once the concrete has cured enough to be self-supporting, commonly 24 to 48 hours after pouring depending on weather and mix.
What happens if forms come off too early?
Edges slough off, corners break away, and the slab can crack, permanently damaging a brand-new sidewalk.
What should be done right after form removal?
Backfill the exposed gaps along soil or lawn areas promptly so no drop-off or trip hazard is left at the slab edge.
