Who is Thunderground

The Difference is in the Design and the Details. When is a storm shelter more than just a steel box in the ground? When it's Thunderground Storm Shelters - the only storm shelter system to our knowledge in the state that is actually engineer-designed and tested. Thunderground hired well-respected engineering firm Crafton Tull to design the best storm shelters on the market. We put research and reason behind our designs and will continue to do so as we create custom storm shelters to meet the needs of upscale buyers, builders, businesses, schools, neighborhoods and developers. Check out our engineering page for the standout attention to detail in Thunderground Storm Shelters.

Our competitive pricing ensures you are getting the most value for your investment. With five models, custom shelters and add-ons available, we can truly provide the right solution for your safety needs. We do installs in any garage, will have aboveground safe rooms available in the future, and offer custom shelters for anything imaginable.

If you are currently building a home, business or apartment complex or other residential area, please have your developer contact us so you can include the shelter in your plans. If you are a developer, builder, own a business or are involved in any community project, we are able to design shelters for any size or need.

Thunderground is proudly serving Oklahoma, Texas, Kansas, Arkansas and Missouri. We currently have dealer opportunities available in the future.
