Technical Inquiries: Frequently Asked Questions
How do I know if my sidewalk needs professional repair?
Warning signs include structural cracks wider than 1/2 inch, vertical height differences between slabs that create tripping hazards, or the receipt of a formal NYC DOT sidewalk violation notice.
Can Harbor Waterproofing help with NYC DOT sidewalk violations?
Yes, we provide end-to-end violation remediation. This includes securing the necessary DEP and DOT permits, performing the technical repairs to city code, and coordinating the final inspection to clear the violation from your property record.
What materials are used for industrial-grade concrete repairs?
We utilize high-strength, low-slump concrete mixes specified by the NYC Department of Design and Construction. These materials are chosen for their ability to withstand heavy pedestrian loads and the freeze-thaw cycles typical of New York winters.
How long does a sidewalk replacement project take to complete?
Most standard residential and commercial sidewalk pours are completed within 48 to 72 hours. While the surface is walkable within 24 hours, we maintain barriers for up to 7 days to ensure the concrete cures to its full engineered strength.
