Tornado Haven™ Underground Steel Storm Shelters
Clean, Dry, Safe
During World War II building concrete storm shelters and bomb bunkers became popular. However, these temporary shelters could not stand the test of time. The reason concrete shelters are cheaper is because over time they can crack in the icy cold of winter, leak water in the spring, and accumulate hazardous mold and mildew in the summer. This is especially true in the high heat, humidity, and unique soil conditions of the Midwest (where the greatest threat posed by tornado alley exists). As the concrete expands and contracts due to the constant heating and cooling throughout the four seasons, the structural integrity breaks down. As cracks become worse in concrete shelters, they need to be repaired on a constant basis which is expensive and time consuming. If left untreated, the entire concrete structure can begin to collapse. Above ground concrete shelters are even more prone to seasonal structural breakdown and are an eye sore due the giant mound in your yard after installation.
Why is a Tornado Haven™ Steel Storm Shelter better than Fiberglass?
Fiberglass may be higher quality than concrete but it still has huge weaknesses. Fiberglass is prone to deterioration from the suns ultraviolet rays. Fiberglass also shares three enemies with concrete shelters: moisture, mold, and mildew. Over time the mold and mildew can deteriorate the fiberglass and the maintenance cost is more expensive than concrete to repair.
