Unique in the industry is our use of expensive additives in our concrete that make it “self-sealing”. Should a small crack ever form in your shelter creating a leak, our concrete can seal the leak forever in a matter of weeks depending on temperature. This protection against leaks is effective for at least 40 years and probably indefinitely. The walls are 3″ thick, the ceiling and floor are over 4″ thick, and the shelter weighs approximately 12,000 lbs.
