Defender Technologies LLC introduced a revolutionary and patented building system called PermaStrong. The PermaStrong building system utilizes pre-fabricated fiber cement wall forms, rebar and concrete fill assembly, which provides numerous advantages for residential and commercial buildings including superior structural strength, faster construction, and reduced labor costs. PermaStrong structures can withstand winds as high as 200 mph, minimizing damage from hurricanes and tornados. According to a major trade publication, although 70 percent of the world lives in concrete structures, that number is only 15 percent in the U.S.
PermaStrong wall forms are assembled off-site and then transported to the work-site where they are positioned and locked in place with rebar. Once in position, the wall forms are then filled with a concrete or cement mix. The wall section remains with the dried concrete for the life of the building, unlike other wall forms that need to be removed from the concrete after it dries. Because the PermaStrong building system is more rigid than wood frame and steel frame structures it also enhances roof attachment strength. PermaStrong structures are also resistant to fire, water and earthquakes. They can also withstand light ballistics, providing protection from objects being hurled at buildings from high winds or a tornado.
