At Core Construction Group LLC, we provide expert concrete installation, repair, and restoration services across New York City, serving Brooklyn, Manhattan, Queens, Bronx, and Staten Island.

From sidewalk violation removal to structural concrete work, we deliver durable, code-compliant solutions built to meet NYC DOT and DOB regulations. With extensive experience in residential, commercial, and public work, our team ensures every project is completed with precision, safety, and long-term performance.

Concrete is one of the most critical components of your property's structure and exterior. Over time, exposure to weather, heavy use, and ground movement can cause cracked or uneven sidewalks, trip hazards and DOT violations, surface deterioration and spalling, and structural weakening.
