Tornado protection is all about the strength of your storm shelter. In Oklahoma, where extreme storms can turn deadly in minutes, you can’t afford to take chances. That’s why Oklahoma Shelters builds every storm shelter to meet (and often exceed) the rigorous standards of the Texas Tech Impact Test. But what exactly is this test, and why is it so important for safety?
What Is the Texas Tech Impact Test?
The Texas Tech Impact Test was developed by the Wind Science and Engineering Research Center at Texas Tech University. It’s considered the gold standard for evaluating safe rooms and storm shelters. The test simulates the impacts caused by tornado debris, such as a two-by-four plank traveling at 100 miles per hour, to ensure a shelter can withstand the real-world forces of a severe storm.
It’s not just about surviving strong winds. Flying debris is one of the leading causes of injuries during storms. Passing the Texas Tech Impact Test proves that a shelter can protect occupants from both extreme wind pressure and high-speed debris impacts, exactly the kind of threats faced during Oklahoma’s tornado season.
Why the Test Matters for Storm Safety
In cities like Norman and Oklahoma City, tornadoes can form with little warning. The impact test ensures your tornado shelter is ready for those unpredictable moments. Without this testing, there’s no guarantee a structure will hold up against the intense pressures and impacts of a real storm.
That’s why at Oklahoma Shelters, every product we install, whether it’s an in ground storm shelter homeowners need, a garage shelter, or a concrete tornado shelter businesses choose, must pass the Texas Tech Impact Test. It’s our way of making sure safety isn’t just promised; it’s proven.
How We Go Beyond the Standards
Passing the impact test is only the starting point. Our underground cement shelters and concrete storm shelter models are reinforced beyond the required specifications. We use high-grade materials, thick steel plating, and structural designs that resist leaks and corrosion. Every storm shelter project includes a 10-year warranty for long-term peace of mind.
We also offer garage shelter installations that save space while providing maximum safety. These units are installed below the garage floor, allowing you to park as usual while still having instant access to protection during severe weather.

Whether you’re considering a safe rooms installation for your home, an in ground storm shelter for your yard, or a garage shelter, our commitment to safety is unmatched. Each shelter is engineered, tested, and certified so that when the skies turn dark, you have complete confidence in your protection.
