Below Ground Storm Shelter FAQs
How many people fit in a below ground storm shelter?
What kind of access do you need for delivery and installation?
Yard access, surface conditions, and equipment clearance can affect placement and installation logistics. These factors are reviewed before installation so expectations are clear.
To drive our equipment into your property, we generally need:
- At least 10 feet of clear width
- Approximately 14 feet of vertical clearance
- A reasonably straight access path
To set the shelter, we need space to extend our outriggers:
- About 18–20 feet of width
- Approximately 20–25 feet of overhead clearance
Not sure if your space will work? Call or text us and we’ll pull up your property on our map to help review access options before scheduling or review our full guide on storm shelter installation access requirements to understand what to expect before installation day.
What should I expect with a below ground storm shelter installation?

Storm Shelter Installation Process
Is Easy Access the easiest storm shelter you offer?
Among below ground models, it is one of the easier entry options. Across all shelter types, above ground storm shelters are typically the easiest overall because there are no stairs.
How long does installation take?
Below ground storm shelter installation is typically completed in 3-4 hours. Because excavation is required, scheduling depends on site conditions, access, and the additional space needed compared to an above ground installation. Weather conditions may affect timing, and we communicate any changes promptly.
How do below ground shelters compare to above ground shelters?
How far in advance will I know my installation date?
You will receive a scheduled installation date at the time of booking. Weather delays are possible, particularly during spring and fall months. If conditions require rescheduling, we communicate updates as soon as possible and work to accommodate your schedule.
How are the underground storm shelters ventilated?
Our below ground storm shelters are designed with multiple ventilation features to promote airflow during occupancy. Each shelter includes a 3-inch vent and an 8-inch turbine vent. These components work together to allow continuous airflow and help keep the shelter comfortable during severe weather events.
This setup is standard across our below ground shelter models.
When is the best time to install a below ground storm shelter?
Can a below ground storm shelter be used as a root cellar?
Are there grants or rebates available for below ground storm shelters?
Yes. Many Oklahoma homeowners qualify for tribal assistance programs and other funding options that can help cover part or even all of the cost of a storm shelter.
Sprague’s Backhoe works with several of these programs and can provide documentation for your application.

Are below ground storm shelters the best option for every homeowner?
Not always. Below ground shelters are a great fit for many properties, but factors like mobility, accessibility, yard space, and installation access can make above ground shelters a better choice for some families.
If you are unsure which option is right for you, take our quick storm shelter quiz to get a better idea of what fits your home.
Do underground shelters require maintenance?
Below ground storm shelters require minimal maintenance. It is recommended to periodically inspect the door and hardware, grease hinges as needed, and make sure the surrounding ground stays stable and drains properly.
Keeping the entry area clear of debris and checking for any changes after heavy rain can also help ensure long-term performance.
