Fireproofing Inspections

Spray Applied Fireproofing

Craig Testing Laboratories (CTL) provides field spray applied fireproofing inspection services to monitor the placement of the spray applied fireproofing material onto the structural steel for compliance with the approved project documents. The inspection consists of inspecting the preparation of the steel for the application of the fireproofing material, measurement of the material for compliance with the required fire-rating thickness, obtaining samples for laboratory testing of density and performing field bond strength testing of the fireproofing material to ensure adequate adhesion/cohesion strength to the steel.

Intumescent

Craig Testing Laboratories (CTL) provides field intumescent inspection services to monitor the placement of the Intumescent material onto the structural steel for compliance with the approved project documents. The inspection consists of inspecting the preparation of the steel for the application of the Intumescent material and measurement of the material for compliance with the required fire-rating thickness.

Intumescent is a substance which swells as a result of heat exposure, thus increasing in volume, and decreasing in density. Intumescents are typically used in passive fire protection on structural steel in thin film.

Firestopping/Firesafing

Craig Testing Laboratories (CTL) provides field firestopping / firesafing inspection services to monitor the placement of the fire resistant material onto the openings and joints in a fire-resistant rated wall and/or floor assembly for compliance with the approved project documents.

Firestopping / Firesafing is a passive fire protection system of various components used to seal openings and joints in fire-resistance rated wall and/or floor assemblies. Unprotected openings in fire separations void the fire-resistance ratings of the fire separations that contain them, allowing spread of fire past the limits of the fire safety plan of the entire building. Firestops are designed to restore the fire-resistance ratings of rated wall and/or floor assemblies by impeding the spread of fire through the opening by filling the openings with fire resistant materials.
