Storm Shilters

The "Family" is our most popular in-ground shelter model with its 6' x 8' interior.finished_install_of_slop_front_shelter.jpg

The ceiling height inside is 6'2" inches and the shelter is rated for 8 people. Many shelters of this model were in the paths of the terrible storms that ravaged Moore, Oklahoma and surrounding cities in 1999. One of those shelters ended up with more than 20 people inside. This model is also the shelter of choice for President Bush on his Crawford, Texas ranch.

Built to standards recommended by FEMA, the Original is constructed of 6,000 PSI concrete with fibermesh and reinforced with 3/8" inch rebar every 12 inches running both directions. The walls are 3" thick, the ceiling and floor are 4" thick, and the shelter weighs approximately 12,600 lbs.

This model comes with an 8" screened turbine vent, a 6" screened intake vent, an interior fixed staircase with dual hand rails, a leak proof 14 gauge steel door with three high strength hinges and a three point/lockable latch & handle. The door also has a support cylinder that makes it easy to open and close.

The Original is installed 4 1/2 ft. into the ground with approximately 2 ft. remaining above grade. The dirt from the excavation is then mounded around the above grade portion on three sides creating a small mound and completely surrounding the shelter with earth. Normal installation can be completed in less than 3 hours.


The "
1stairs_out_and_hinge_of_slop_front_shelter1.jpgJumbo" is our largest in-ground shelter model with its 6'10" x 10' interior.

The ceiling height inside is 6'2" inches and the shelter is rated for 12 people. Based on the time tested design of our Family shelter, the Jumbo offers more room to stretch out in an extended storm.

Built to standards recommended by FEMA, the Jumbo is constructed of 6,000 PSI concrete with fibermesh and reinforced with 1/2" inch rebar every 9 inches running both directions. The walls are 4" thick, the ceiling and floor are 5" thick, and the shelter weighs approximately 20,000 lbs.

This model comes with an 8" screened turbine vent, a 6" screened intake vent, an interior fixed staircase with dual hand rails, a leak proof 14 gauge steel door with three high strength hinges and a three point/lockable latch & handle. The door also has a support cylinder that makes it easy to open and close.

The Jumbo is installed 4 1/2 ft. into the ground with approximately 2 ft. remaining above grade. The dirt from the excavation hole is then mounded around the above grade portion on three sides creating a small mound and completely surrounding the shelter with earth. Normal installation can be completed in less than 3 hours.

 

Manufacture Warranty

The manufacturer warrants that there will be no leakage in the concrete structure for a period of 10 years from the date of installation. This includes the seal where the two (2) units are joined.

The warranty does not include moisture that may appear from time to time in the form of condensation, commonly due to temperature variations, humidity, etc. Neither does the warranty include water that may enter the structure through the door or ventilator.

Small cracks caused by expansion and/or contraction which do not create a leakage or structural problem are not covered by the warranty.

Adding Utilities

Our shelters do not come pre-wired for electricity or any other utilities. These items can be added following installation if desired. U.S. Storm Shelters recommends using a licensed professional electrician or telephone installer to handle these additions.

For concrete shelters, have your electrician drill any necessary conduit access holes in the base of one of the vent shafts on the roof of the shelter. This is far easier than attempting to drill through concrete and allows for easy installation of conduit and a clean seal. In some cases, a cell phone will work in these units but service varies by location and equipment.

Safe rooms can be modified for electricity and telephone by simply running conduit through the vent space below the door.
