A panel is a leveling candidate if the concrete is intact but has settled due to soil movement beneath it. Replacement is needed when the panel has crumbled, fractured into multiple pieces, or the surface has deteriorated from freeze-thaw damage to the point where structural integrity is compromised. Scaldino's assessment will confirm which approach applies.

Polyurethane foam injection can be performed in temperatures above 35 degrees Fahrenheit, making it viable for most of New Jersey's winter. Mudjacking is more temperature-sensitive and is generally not recommended below 40 degrees as the slurry can freeze before curing. Scaldino will advise on timing based on forecast conditions.

Leveling lifts a sunken panel back to grade to eliminate the height differential. Grinding shaves down the raised edge of the higher panel without lifting the lower one and it is faster and less invasive but only practical for lips under 1.5 inches. For larger differentials, leveling is required first, followed by grinding to finalize the transition.

A cracked but structurally sound sidewalk panel can be lifted and stabilized. The crack itself will not disappear and patching or joint sealing is done after leveling to prevent water intrusion. Panels that have shattered into multiple fragments may need replacement rather than lifting.

A typical sidewalk leveling job involving 2 to 4 panels can be completed in 1 to 2 hours. Polyurethane foam cures in 15 minutes, meaning pedestrian traffic can resume the same day. There is no need to close the sidewalk for extended periods as there would be with concrete removal and replacement.

In most New Jersey municipalities homeowners are responsible for maintaining the sidewalk adjacent to their property, including repairs to sunken or cracked panels. Failure to repair a trip hazard can expose the homeowner to liability if someone is injured. Scaldino can provide documentation of the repair for liability and insurance purposes.

Yes. Concrete leveling lifts sunken sidewalk panels back to grade, eliminating the height differential at slab joints that creates trip hazards. For minor lips under one and a half inches, concrete grinding can shave down the raised edge without lifting the slab. Both approaches remove the hazard and the associated liability for property owners.

Concrete leveling typically costs 50 to 75 percent less than full replacement by eliminating demolition, disposal, new pours, and extended curing time. For slabs that are structurally sound but have settled, leveling is almost always the more cost-effective solution. Replacement is only warranted when the concrete itself has deteriorated beyond repair.

Most residential concrete leveling jobs are completed in one to three hours depending on the number of slabs and severity of settlement. Polyurethane foam injection cures in 15 minutes, allowing same-day use. Mudjacking requires 24 to 48 hours before the area can be driven on.

Concrete sinks when the soil beneath it erodes, settles, or washes away due to poor compaction, water infiltration, or natural soil movement over time. Tree roots, freeze-thaw cycles, and heavy loads can accelerate this process. Concrete leveling restores the surface without the cost and disruption of full replacement.
