A “GAME CHANGER” in Shotcrete innovation and technology.

Featuring our newest product - STI “Fire Stop”

STI “Fire Stop” is a sprayable cementitious inorganic fireproofing material with excellent adhesive bonding to a variety of surfaces, concrete, steel, wood etc. STI “Fire Stop” releases no toxic fumes during application nor during fire. The STI “Fire Stop” Mortar includes volcanic ash and is expected to outlast ordinary concrete in quality and lifespan. This structural material meets or exceed most international specifications for passive fireproofing in public transportation tunnels and other infrastructure. Also used in mines to control “hot” areas.

We tested in-house 1/2” to 3/4” samples for 4 hours at 2400 degrees F to the front and never exceeded 800 F on the back side of the material.
