Underground Garage Storm Shelters

Learn more about our underground storm shelters

​Our underground garage tornado shelters are unique because we install them in your garage and they do not require extra square footage. Also, your vehicle can be parked normally over the storm shelter, still allowing you access whenever needed. This space saving design allows you to stay out of inclement weather and harm’s way. We offer this shelter in two sizes and two installation types. 

Large:              39” x 7’ x 56”             Hole size- 44” x 7’7”               Holds 7+ people

Extra large:   60” x 7’ x 61”             Hole size- 66” x 7’7”               Holds 11+ people

Deluxe installation: In-garage underground storm shelter with deluxe installation. This shelter is installed with the following:

  • Backfilled with ready-mix concrete from concrete truck and poured on all four sides from top of the shelter to the bottom.
  • Storm shelter comes with a come-along hand wench for extra leverage when opening sliding door if debris is on the lid
  • Storm shelter comes with a magnesium anode buried underneath, this draws the electrolysis out of the soil and it consumes the anode instead of the steel
  • Dust-free installation because the concrete is cut with a diamond blade wet saw


Standard Installation: In garage underground storm shelter with standard installation. This shelter is installed with the following:

  • Backfilled with dirt to the top u-crimp and then backfilled the remainder of the way with sack concrete
