How in-ground shelters work
An in-ground shelter is a steel or precast concrete unit buried in your yard, with a hatch or angled door at ground level and steps leading down. Earth around it adds protection from wind and debris. The door is the critical part and must be tested along with the shelter.
Steel or concrete?
- Steel shelters are lighter, easier to deliver and set, and well suited to tight backyards.
- Precast concrete shelters are very heavy and need a crane or heavy equipment, but resist corrosion well. Either can meet ICC 500 if the specific model is tested.
Site considerations in the Panhandle
- Digging. Caliche and hard layers are common in places. The installer may need a larger excavator or a rock attachment.
- Water. Choose a spot away from low areas where water collects during heavy rain. Ask about waterproofing, drainage and how the shelter is anchored against being pushed up by wet soil.
- Distance from the house. You'll be walking outside during a warning. Closer is better, with a clear, lit path.
- Utilities and access. A Texas 811 locate is a must, and the installer will need equipment access to your yard.

Be ready to get out
Keep a charged phone, weather radio, flashlight and whistle in the shelter, and register it with local emergency management if a registry is available, so responders know to check it after a storm.
