Surface patching A temporary cosmetic fix where a thin layer of mortar or concrete patch mix is spread over minor surface cracks or spalls.
Although surface patching is a quick way to smooth over minor cosmetic pitting, it has a very short lifespan in the harsh NYC winter freeze-thaw cycle. Furthermore, the NYC DOT does not accept surface patching as a valid repair method for clearing sidewalk violations. Property owners should avoid wasting money on temporary patches and instead opt for a code-compliant flag replacement.
Frequently Asked Questions About Surface patching
What is surface patching?
Spreading a thin layer of mortar or patch mix over minor surface cracks or spalls as a cosmetic fix.
Does DOT accept surface patching to clear a violation?
No. Patching is not an accepted repair method for a cited sidewalk flag, which requires full-depth replacement.
How long does a patch last in NYC?
Usually not long. Freeze-thaw cycling and de-icing salts break the bond between the thin patch and the slab beneath.
Is patching ever useful?
For temporary appearance on private surfaces, but it is not a durable or compliant solution on a public sidewalk.
