Door Tested by the Wind Science & Engineering Research Center at Texas Tech University

All partial underground storm shelters are steel reinforced with rebar poured with a 5,000 psi (28 day) compressive strength concrete mix. Each storm shelter has an 8" turbine vent and a 6" inlet.  Our storm shelters feature a handrail design with steps and metal door with two locking mechanisms.  The top and bottom sections are tied together with four 2' x 12" x 3/8" steel straps and 5/8" diameter grade 8 bolts.

What do you need to know when determining where to put your partial underground shelter?
  • Our semi-type boom truck is approximately 14 feet tall; clearance to your shelter location will be required.
  • You need to find out if a building permit is required to install your above ground storm shelter. If so, you are responsible for obtaining the correct permit.
  • Most municipalities require shelters to be 3 feet from property lines; verify your distance required.
  • Do not place shelters over underground utility lines or underneath hanging utility lines.
  • Do not place shelters in areas that may be subjected to flooding.
  • Put in a location that will be quickly and easily accessible.
  • C.R. Barger & Sons, Inc. does not offer the excavated hole.

How should the shelter hole be excavated?
  • A 46” deep by 78” wide by 138” long hole which allows for a six-inch gravel foundation (required for shelter installation).
  • The entire bottom half of the shelter is buried below finished grade. This process is a minimal impact to your yard and provides ease of access for your family during a storm.

Why should you purchase a precast concrete partial underground storm shelter from us?
  • Our shelter designs were evaluated by an independent, third party engineer for conformance to the NSSA standard.
  • Peace of mind in knowing that your shelter is manufactured using high strength materials.
  • Shelter is designed for wind speeds of 250 MPH which are greater than that of an Enhanced F-5 tornado.
  • Precast concrete shelters have low electrical conductivity and noise resonance.
  • Most cellular services are not significantly affected when inside a precast concrete shelter.
