Cementitious or wet mix fireproofing is mixed with water and pumped under pressure through hoses to a nozzle where air is introduced. The wet slurry is then broadcast onto structural steel surfaces. The inherent fire resistive mechanism of products is the release of water, in the form of steam, when exposed to elevated temperatures. Products are available in standard, medium and high density for use indoors and on building exteriors. We provide customers with cementitious fireproofing from vendors such as W.R. Grace & Co., Isolatek International and Carboline Co.
