Tree Root Damaged Concrete Repair NYC

It depends on the severity. Minor lifts under an inch can be ground smooth or lifted with slab jacking, while slabs that are cracked or heaved more than an inch typically need to be demolished, the root pruned or barriered, and the section repoured with rebar doweled into the surrounding stable concrete.

Driveway repair due to tree roots follows the same logic as sidewalk repair: level or grind minor damage, or demolish and repour severely cracked sections. We saw cut and dowel new concrete into the existing driveway and install a root barrier along the affected edge to stop the damage from recurring.

Property owners are generally responsible for sidewalk repair under NYC Administrative Code §19-152, even when a City tree caused the damage. However, NYC Parks' Trees & Sidewalks Program may repair damage caused by a City street tree at no cost for eligible one-, two-, and three-family owner-occupied homes, based on funding and severity.

Usually, yes. In many cases, the affected pavers can be lifted, the base adjusted around the tree roots, and the pavers reset at the proper grade. Tree removal or root cutting is generally not necessary, and in NYC, unauthorized tree removal or root cutting is not permitted.

Grinding shaves down small raised lips while in slab jacking, we pump foam or grout under a sunken or shifted slab to relevel it without demolition. Full replacement is needed when a slab is cracked, broken, or heaved beyond what leveling can fix.

Not if it's done correctly. We coordinate with a certified arborist to identify which roots can be safely pruned without harming the tree's stability or health and use root barriers instead of cutting wherever structural roots are involved.

Yes, in most cases. Grinding and minor leveling are sometimes exempt, but slab replacement almost always requires a DOT sidewalk permit. If the work involves excavation within 50 feet of a city tree, NYC Parks also requires a separate Tree Work Permit before any digging near the root zone can begin. Parks generally won't issue it earlier than 5 business days before your start date, and the Borough Forestry Office needs at least 72 hours' notice before work starts. Skipping this permit when roots are involved can result in fines up to $15,000. We file and manage both the DOT and Parks permits and coordinate the required inspections through final approval.
