Concrete Cutting for Fire Sprinkler Systems

Fire sprinkler system installations and retrofits require precise penetrations through concrete floors, walls, and ceilings for risers, main supply lines, and branch piping. REDCORE provides professional concrete cutting and core drilling services tailored to fire protection contractors who need clean, accurately positioned holes for sprinkler piping in both new construction and retrofit projects throughout Massachusetts. Our diamond core drills create smooth, round penetrations that accept fire-rated sleeves and allow proper sealing around sprinkler piping, maintaining the integrity of fire-rated assemblies as required by NFPA 13 and the Massachusetts fire code.

Fire sprinkler retrofits in existing buildings present unique challenges because the concrete is already in place and the building is often occupied. REDCORE works within these constraints, performing core drilling during off-hours when necessary, containing dust and slurry to protect occupied spaces, and coordinating closely with fire protection contractors to ensure every penetration is in the correct location at the correct diameter. We drill penetrations for vertical risers through floor slabs, horizontal mains through foundation and fire walls, and branch line feeds through concrete ceilings and beams. Hole diameters typically range from 2 inches for individual branch lines to 8 inches or larger for main risers and supply lines.

Our operators understand fire protection system requirements including the importance of maintaining fire-rated separations, proper clearances for fire stop materials, and the need for precise positioning to match sprinkler head layouts. We coordinate with fire protection engineers and installing contractors to deliver penetrations that meet project specifications and code requirements, keeping your sprinkler installation project on schedule and in compliance.
