Premium Fire-Rated Core Hole Assembly Systems


Installation consists of grinding slots in the existing floor, applying fire-rated sealant, and installing the plug assembly (CorPlug) flush with the existing floor.

Restoring Fire-rated Integrity and Code Compliance

Commercial building modifications frequently leave behind a hazardous byproduct: abandoned floor penetrations. When communication lines, plumbing conduits, electrical feeds, or structural sleeves move, the resulting voids compromise the entire facility's safety envelope. These unsealed openings act as chimneys during building fires, allowing toxic smoke to migrate between floors rapidly. Building owners face immediate fire-life safety vulnerabilities along with severe code violation fines if these penetrations remain neglected.

CorPlug designs advanced engineered components specifically to eliminate this widespread safety hazard. We manufacture high-performance, patented precast floor plug assemblies engineered to restore the industry fire-rated integrity to concrete floors. Incorporating a certified fireproof core hole assembly into your repair workflow rectifies these abandoned core holes permanently. To that end, our mission centers on delivering rigorously tested components that streamline facility improvements while offering straightforward fire protection to commercial properties nationwide.

Streamlined Overhead Installation Methods

Traditional floor core repairs demand extensive labor and disruption. Traditional methods require technicians to obtain scheduled permission, building supervision and pass-downs, coordinate with tenants below, and it accessible, build complex under-floor formwork to retain poured concrete. Our advanced fire-rated core hole assembly system reengineers this tedious process entirely with installation done from above.

Using CorPlug, the only pre-cast fireproof core hole assembly, ensures that the installation occurs entirely from the top side of the concrete slab. Workers insert the precast unit directly into the void from above, avoiding the need to access the ceiling space on the floor below. This innovative top-down approach protects your tenants from noisy, dirty construction disruptions and removes the liability risks associated with overhead ladder work.

 

Engineered Defenses for Demanding Modern Facilities

Utilizing a certified fireproof core hole assembly protects your commercial property against unexpected fire-life safety threats. Each specialized fire-rated core hole assembly acts as a robust thermal shield, sealing away open pathways to prevent the spread of fire, smoke and noxious gases. This immediate containment limits property damage and provides crucial evacuation time for occupants.

Beyond emergency performance, our precast plugs deliver substantial project cost savings by reducing active labor hours. Installation teams can patch dozens of abandoned openings using a dedicated fire-rated core hole assembly in a fraction of the time required for traditional pan repair, forming, doweling, mixing and pouring concrete. This rapid turnaround helps your facility remain compliant with building regulations during major interior renovations.

Frequently Asked Questions

Do these precast plugs require specialized tools for standard jobsite installation?
No. Installation relies on standard hand tools similar to a 4.0" grinder, along with commercial-grade caulking guns to apply the specified fire-rated sealant material.
What specific fire-resistance hourly ratings have these assemblies achieved during testing?
Our engineered plugs have successfully passed the ASTM E-814-13a standard test to achieve a full two-hour fire resistance classification.
Can these precast systems accommodate non-standard or irregular core diameters?
Yes. We manufacture our units to match standard nominal core hole diameters (1.0"-6.0" half sizes included) common in commercial construction, though custom sizes can be evaluated.
How soon can a floor space be subjected to regular foot traffic after installation?
Following the specified installation procedure secures the unit within minutes, allowing for the final floor finishes to be installed.
Are these assemblies suitable for exterior concrete slabs, parking structures or moisture-heavy environments?
No. Our core repair plugs are designed specifically for the interior of multi-level buildings to maintain fire barriers between building floors.
