7x10 Jumbo Slope Front Storm Shelter

A 7×10 jumbo slope front storm shelter generates approximately 2-3 dump truck loads of leftover dirt from excavation. Sprague’s Backhoe offers dirt haul-off services for an additional fee if you don’t want to keep the excavated soil on your property. Many homeowners use the dirt for landscaping projects, filling low spots, or building up areas of their yard. We’ll discuss your dirt removal options during scheduling.

Most Oklahoma cities require permits for below ground storm shelters. Requirements vary by municipality – Oklahoma City, Norman, Moore, and other cities have specific permit processes. You’ll need to obtain the permit yourself, but Sprague’s Backhoe provides all the documentation your city requires including engineering specifications and installation details. We recommend checking with your local building department early in the process.

Your 7×10 shelter comfortably protects 14-16 people with 70 square feet of interior space. This is our largest below ground option, making it ideal for extended families, multi-generational households, or anyone who wants maximum capacity. You’ll have room for seating, emergency supplies, and comfortable protection during severe weather events.

This focused service area includes Oklahoma City, Norman, Moore, Mustang, Newcastle, Tuttle, Chickasha, Blanchard, and surrounding central Oklahoma communities. Below ground installations require excavation equipment and specialized installation expertise that we provide within this service radius.

Installation of your 7×10 below ground storm shelter typically takes 3-4 hours depending on soil conditions, site access, and weather. We schedule installations Monday through Friday and handle all excavation, placement, and backfill work. Sprague’s Backhoe will provide a specific timeline during the site assessment based on your property conditions.

Every 7×10 shelter bottom is coated with Epro, a water-resistant coating that helps prevent water intrusion. The shelter also includes an anti-floatation ring to prevent shifting during heavy rains or flooding conditions. Proper drainage and site grading during installation further minimize water concerns. While no underground structure is completely immune to water, our installation methods and protective coatings significantly reduce flooding risks common to Oklahoma’s clay soil and weather patterns.
