Jackhammer / breaker A heavy-duty pneumatic or electric tool used to break up old, cracked concrete sidewalk flags, curbs, or asphalt during the demolition phase of a repair.
Before a new, compliant sidewalk can be poured, the existing damaged pavement must be removed. The jackhammer is the primary tool used by NYC contractors to crack and shatter old concrete flags quickly. Demolition crews must operate jackhammers with skill to prevent cracking the neighboring sidewalk flags, which could result in additional violations. Contractors must also abide by NYC noise regulations and safety protocols when utilizing jackhammers in busy pedestrian corridors.
