Underground Storm Shelters Enid

Enid underground storm sheltersOn May 3, 1999 an EF5 tornado struck Moore, OK that’d record wind speeds of over 300mph. After that 1999 tornado, we realized that not everyone in Oklahoma had the room to install a septic tank protector. People had very, very limited choices with respect to protecting their families from tornadoes. At that time, underground storm shelters in Enid were not installed in half the houses they are now.

Immediately thereafter, the first generation of the in-garage, underground storm shelters was born. This allowed for the masses to put in a shelter underground, in their home for tornado protection. Homes throughout Enid were installing these underground storm shelters to protect themselves.

This was a fantastic thought for sheltering people and keeping them from the weather but it had its downfalls. It stuck up 4 to 5 inches away from the garage floor, had poor ventilation, rusted out fast, and had steep, awkward ladders for entry and exit. A number of these underground storm shelters in Enid weren’t installed properly and have really floated up from the ground because of buoyancy and ground water. We took note, and made history.

In 2003, the FlatSafe Tornado Shelter was invented. We engineered our underground storm shelters, to be set up in-garage to take care of the destructive forces connected with tornadoes that would offer our Enid customers peace of mind and provide them with the maximum probability of survival in an EF5 tornado.

Through instense research, we identified vacuum, air pressure, and debris as the most destructive forces connected with tornadoes.

  • Vacuum

With possible wind speeds of 300+mph in mind, we realized that vacuum is one of the most damaging forces which tornadoes create. It doesn’t require much vacuum pressure, with regard to psi, to cause structural damage. To counter vacuum forces, FlatSafe made a lid system that permits 360o of venting for rapid equalization of pressure within the shield. By boosting the pressure inside of the shelter to quickly equalize with the outside pressure, the secured lid system is held firmly closed.

  • Pressure

We recognized that 300+mph winds can cause tremendous damage to anything it slams against so we sought to lower our exposed surface area as far as possible. The patented FlatSafe lid system only sticks up 1/4″, therefore there’s very little surface area affected by horizontal wind speeds.

  • Debris

Because FlatSafe Tornado Shelters are under ground, it’s from the way of horizontal winds and the debris thrown and circulated by it. So the only debris to worry about is falling debris. We understood that all debris falls at exactly the same speed and only mass determines its effect. Our 1/4″ plate lid is bigger than the shelter opening and is reinforced to absorb and withstand any falling debris that might land squarely on it. We made it to provide more than adequate ventilation (breathing) even after effect.

FlatSafe Underground Storm Shelters

Below Ground Storm Shelters EnidThe FlatSafe Tornado Shelter was engineered to meet all of the regulations and criteria which were available. It was also engineered with rust protection options to make sure that the shelter would last as long as the home and the homeowner. FlatSafe provided the first single-lid design and was the first low-profile, in-garage shelter given. The lid is 1/4″ thick steel plate with added structural tubing to give additional strength. The single-piece lid is bigger than the framework of the saferoom opening and sits above the framework, not down inside the frame.

Our lid system is MUCH stronger than the normal 2-piece lid system offered by everyone else and provides more than adequate ventilation to the occupants. FlatSafe was the first to encase shelters in ready-mix concrete to counteract buoyancy and floatation. The FlatSafe shelter design doesn’t take away from a homeowner’s usable garage floor space.

FlatSafe below ground storm shelters allow for easy entry and exit, provides a powerful system for exiting with debris on the lid, and leaves Enid residence with the peace of mind that they have a very large probability of surviving a direct hit from an EF5 tornado.
