Robust wall system defends against hurricanes, tornados

Gulf Shores, Ala.-based Defender Technologies, LLC has introduced a patented building system that can withstand winds as high as 200 mph, minimizing damage from hurricanes and tornados. PermaStrong utilizes pre-fabricated fiber cement wall forms, rebar and a concrete fill assembly, providing superior structural strength, faster construction, and reduced labor costs.

PermaStrong wall forms are assembled off-site and then transported to the project site, where they are positioned and locked in place with rebar. Once in position, the wall forms are then filled with a concrete or grout 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.

“We believe PermaStrong is a superior alternative to traditional building structures that have either been damaged extensively and failed to withstand the tremendous destruction caused by Hurricanes Sandy, Harvey and Irma,” says Paul Cheek, spokesperson and consultant for Defender Technologies. “We not only see this system being used in the construction of new buildings, but also the rebuilding of homes, schools, commercial space and office buildings. We also anticipate that use of the PermaStrong building system in residential and commercial construction will lower insurance premiums for property owners.”

The manufacturer also notes that PermaStrong structures are resistant to fire, water and earthquakes, and can also withstand impacts when subjected to light ballistics.
