of Your Community Storm Shelter


Step 1: Size

In step one, this is where you determine what size of Stormbox community shelter you need. With multiple sizes to choose from, we will tailor your disaster shelter to best suit your facility or campus needs. The community storm shelter choice is largely based on how many people you need to protect. All listed occupancies are based on five square feet per person as required in the FEMA 361 guidelines for storm safe rooms. Actual occupancy is greater. It’s also worth noting that multiple units can be deployed to meet any occupancy demands. Keep in mind that additional Stormbox community storm shelters can also be added over time as your workforce or campus grows.


Step 2: Foundation

The second step is to determine the specific location for your community storm shelter from Stormbox. It should be out of a flood zone, accessible, and in a central location. Each community storm shelter is bolted to a 4,000 PSI, 16”-thick, reinforced-concrete foundation. Each Stormbox installation includes one handicap-accessible ramp. Step two of the construction process typically takes two days. However, it’s worth noting that it can take the concrete about seven days to cure.


Step 3: Delivery

At Stormbox, we serve the entire United States and have completed projects all across tornado alley. Each Stormbox community storm shelter is manufactured in a quality-controlled manufacturing environment. Stormbox shelters are delivered reliably and cost-effectively on a flatbed trailer directly to your site. We are also conscientious of your schedule and will be sure to schedule delivery for whatever day works best for you. Shipping prices are determined on a case-by-case basis and depend on the distance your Stormbox is being shipped. All community storm shelter units are FOB Little Rock, Arkansas.


Step 4: Anchoring

We utilize a crane to hoist the community storm shelter from the trailer and set it in place on the foundation. We utilize a HILTI epoxy anchoring system using 5/8” bolts with 6” of embedment to ensure the shelter stays in place during an EF-5/250 MPH tornado. This process is completed in only a few hours.


Step 5: Electrical Hook-Up

Once your Stormbox disaster shelter is bolted in place, we will connect it to a permanent power source. We typically locate the electrical conduit stubbed up through the foundation for a clean, professional-looking job. This step is completed in a few hours.


In five easy steps and a handful of days, you can go from being vulnerable to severe weather to completely protected. In most cases, your community storm shelter can be completely installed in as little as one week. If there is a tornado, hurricane, or severe thunderstorm threat, simply enter the shelter and lock the door to be protected from up to EF-5 tornado forces. It’s as simple as that!
