Quick Answer:
The storm shelter installation process involves site preparation, permit verification, utility marking, and professional installation by Sprague’s Backhoe, an Oklahoma business. Above ground installations take 2-3 hours, while below ground installations require 3-4 hours. All shelters are designed and installed in accordance with FEMA P-320 guidelines and ICC 500-2020 standards for tornado protection, though FEMA does not certify individual shelters.
Installing a storm shelter in Oklahoma isn’t just about protection—it’s about peace of mind during tornado season. If you’ve been wondering what actually happens on installation day, you’re in the right place.
Since 2013, Sprague’s Backhoe has served Oklahoma families with storm shelter installations, bringing over 20 years of owner experience to each job. Here’s exactly what you can expect, from the first phone call to the final cleanup.
Before Installation Day Arrives
Getting ready for your storm shelter installation involves a few important steps that happen before our crew arrives at your property.
Site Assessment and Preparation
During our initial phone call, we’ll talk through your property layout and discuss access and placement options. For above ground installations, we need clear access for our crane and delivery truck. Below ground installations require even more space because you need room for excavation equipment, plus space for the hole and a giant pile of dirt.
If you’re still deciding between shelter types, our guide on above ground vs. below ground storm shelters can help you weigh the pros and cons of each option.
Permit Requirements
Most cities require permits for storm shelter installation, so you’ll want to check with your city office to see what’s needed. If you’re outside city limits, you typically won’t need a permit at all. We provide stamped engineer drawings and can offer guidance on what your city might ask for during the permit process.
Utility Locates
Here’s something that takes the stress off your shoulders—we’ll take care of calling OKIE locators the week before your scheduled installation date. This applies to both above ground and below ground installations.
Important reminder: OKIE locators don’t locate private lines like sewer/septic, water/well, propane, or private electric lines (like a line to your shop). If you have any private utilities in the installation area, please let us know during our initial phone call so we can plan accordingly. While rare, any liability for replacement and repairs of private lines would be the homeowner’s responsibility.
The Complete Installation Process
Installation day is straightforward, but the exact process depends on whether you’re getting an above ground or below ground shelter.
Above Ground Installation (2-3 Hours)
Above ground storm shelters are our most popular option, and here’s why the installation process is so efficient:
Site Preparation
We start by scraping the native ground down to level only. We don’t haul in any materials—just prepare the existing surface for your shelter’s foundation.
Delivery Truck Arrival
Our delivery truck arrives with your precast concrete shelter, along with the crane needed for placement. We’ll position our equipment to minimize any impact on your landscaping or driveway.
Placement and Anchoring
Using our crane, we carefully place your shelter in the exact position. Then we anchor it securely to a concrete footer that meets all FEMA guidelines for wind resistance. This anchoring system is what keeps your shelter safe during extreme weather events.
Our above ground storm shelters are engineered to withstand EF5 tornado conditions while providing easy access for your family.
Final Inspection
Before we leave, we’ll do a final inspection to make sure everything meets our quality standards and clean up any debris, leaving your property looking as good as when we arrived.
Below Ground Installation (3-4 Hours)
Below ground installations take a bit longer due to the excavation work, but many families prefer this option as it keeps most of the shelter below ground level while maintaining easy access.
Excavation Process
We begin by carefully excavating the area to the exact dimensions needed for your shelter. Our experienced operators take care to minimize disruption to surrounding landscaping.
Dirt Haul-Off Option
If you don’t want the excess dirt left on your property, we offer dirt haul-off at an additional fee. This must be arranged prior to installation so we can schedule accordingly—we’ll discuss this option during your initial phone call.
Shelter Placement
Once the excavation is complete, we use our crane to carefully lower your precast concrete shelter into position. We ensure proper alignment and that all safety features are correctly positioned.
Backfilling and Site Restoration
We backfill around your shelter with the dirt we dug up. The dirt will be built up to the top of the shelter to allow for natural settling over time. You’ll need to rake it out as it settles. When it’s done settling, you can landscape around it or rake it out to your liking. Some people prefer to keep the mound of dirt around the sides, while others prefer to rake it down level with the ground because it’s easier to mow around.
What Makes Our Installation Process Different
As an owner-operated Oklahoma business, Sprague’s Backhoe brings a personal touch that larger corporations simply can’t match.
Direct Installation by the Owners
When you call us, you’re talking directly to the people who will install your shelter. Jack handles all field installations personally, bringing over 20 years of experience to every job. There are no middlemen or subcontractors—just experienced professionals who care about your property.
Specialized Equipment and Expertise
We own and operate all the equipment needed for storm shelter installation, from cranes to excavation machinery. This means we control the entire process and can ensure everything is done to our high standards.
Property Care and Cleanup Standards
Your property matters to us. We take extra care to protect existing landscaping, driveways, and structures during installation. Our cleanup is thorough because we know you want your yard to look great after we’re done.
After Installation: Next Steps
Your storm shelter installation is complete, but there are a few important things to take care of afterward.
Storm Shelter Registration
After installation, you’ll want to register your shelter with your local emergency management agency. This helps first responders locate you during severe weather or rescue situations. Each city and county handles registration differently, so check with your local agency for their specific process.
Warranty and Contact Information
All our storm shelters come with manufacturer warranty coverage. Keep our contact information handy—we’re always here if you have questions or need assistance with your shelter.
Basic Maintenance
Storm shelters require minimal maintenance. Just grease the hinges annually and keep the interior dry. Condensation is normal, especially right after installation and during colder weather. Simply open the door on dry days to let it air out—just don’t forget to close the door when you’re done.
Frequently Asked Questions
How much notice do you need to schedule an installation?
We typically schedule installations 6-8 weeks out, depending on the season. Spring is our busiest time as families prepare for tornado season, so earlier scheduling is always better.
Do you work in all weather conditions?
We don’t install during severe weather, heavy rain, or when ground conditions are too wet for safe equipment operation. If weather affects your scheduled installation, we’ll reschedule as soon as conditions improve.
What if we discover underground utilities during excavation?
While we handle OKIE utility locates, if we encounter unexpected private utilities, we’ll stop work immediately and discuss options with you. This is rare, but safety always comes first.
Can we use our shelter immediately after installation?
Yes! Your shelter is ready to use as soon as installation is complete.
What happens if the installation takes longer than expected?
Occasionally, unexpected ground conditions or other factors can extend installation time. We’ll keep you informed throughout the process and work efficiently to complete your installation the same day.
Do you install shelters year-round?
Yes, we install storm shelters throughout the year, though spring is our busiest season. Winter installations are possible as long as ground conditions permit excavation for below ground shelters.
Is there anything we need to have ready on installation day?
Just clear access to the installation area and, if you have pets, please keep them safely inside during the installation process. We’ll handle everything else.
