We provide both spray- and trowel-applied fireproofing to exposed structural steel surfaces, roof and floor assemblies, columns, concrete services, and joists in both industrial and commercial environments.

Spray-on fireproofing methods involves the spraying of various products onto construction materials to improve resistance to fire, while decreasing chances of weakening, burning or melting under extreme heat. While trowel-applied fireproof coatings optimize safety and performance, all while mitigating the risks of downtime, damage and injury.

We have completed many difficult projects without incurring unjustified cost overruns, which differentiates us from our competitors.

We were the “fireproofing” contractor of choice for a new dormitory at one of the nation’s top research universities. We also applied intumescent fireproofing, plus low-density cementitious (spray-applied) fireproofing and high-density cementitious (trowel-applied) fireproofing and epoxy and general paint in The University of Virginia’s John Paul Jones Basketball Arena, the largest stadium of its kind in VA!

Intumescent Sprayed Fire-Resistive Materials
Water Based, Solvent IFRMs and Epoxy Intumescent Applications
