Being under the ground is the safest place to be in a twister and an in-ground shelter created to safeguard you in these storms is safer than any basement. Above ground shelters are offered however being above ground simply is not as safe as being in the ground. The most fundamental part of an underground storm shelter is the door. Doors that have been checked to withstand an F5 tornado will certainly be abler to validate that they have exceeded FEMA 320 requirements.

Despite soil condition, water tables or virtually any space building, this shelter installs in 4 hours or less, seats six or even more, has a number of added security functions and has a lifetime service warranty versus material deterioration consisting of cracking, leaking, rotting or rusting.
