Custom Steel Blast Resistant Shelter Installation by Spartan Survival Systems, Inc

Water proof vs water tight

Round corrugated steel blast resistant shelters are built as water-tight units, meaning the seams are good at keeping water out, but in extreme conditions, or prolonged exposure to constant water, it will find a way in. Our interior coating is durable and thick, and can also help prevent water leaking in in such situations, but its not 100%. If you live in a drier area, like Arizona, then water tight is all you need. Wetter ground conditions would be better fit for water proof shelters. We apply a urethane coating to the locked seams, creating a life time guaranteed, waterproof finish. We can do this while still using the corrugated design to allow for maximum burial depth, so there is no sacrifice with ground cover between the decision to water proof.

Our standard floor plan & whats included:

Our blast shelters come standard with a 15' long entrance airlock/decon room, and a small storage/generator unit. Each unit attached is protected by our security barrier, that only Spartan Survival Systems offers. All blast shelters have 3' depth of underfloor storage on 10' DIA and 2' for 8' DIA shelters. Each standard shelter comes with NBC Filter unit, painted interior, floors with storage access, and lights. Our escape hatch is hidden under a layer of ground cover, and is reusable, with lockable steel lid.
