Hazard and Blast Resistant Buildings
Patent pending FORTRESS Protective Buildings are blast resistant buildings constructed from modular components that provide design flexibility as well as multi-hazard protection from fragment, overpressure, thermal, toxic, and extreme weather events. Using innovative modular construction, our buildings are quickly fabricated, shipped, installed, and ready for occupancy.
We have partnered with industry leading companies to offer a turnkey blast resistant building that provides a high degree of protection from a range of hazards. Due to our patent pending modular design, site owners and operators not only benefit from knowing that building occupants will be protected, but can also appreciate that project costs and site disruption will be minimized.

Comparing FORTRESS Protective Buildings to blast resistant structures
You can never be too careful when it comes to protecting your employees and contractors. When the 9-to-5 is at a petrochemical plant, a refinery, or any other facility with hazardous materials or explosive risks, the only responsible way to build is blast resistant. Site or facility managers can purchase blast-resistant structures – permanent or portable buildings to safely house staff during their workday. Unfortunately, it can be tough to tell what type of blast-resistant structure you need. You’ll need to answer questions such as: – What size do you…
