When you live in the heart of Tornado Alley, “home sweet home” needs to be more than just four walls and a roof—it needs to be a fortress. In Oklahoma City, the weather isn’t just a conversation starter; it’s a factor that dictates how we build, how we repair, and how we sleep at night. If you’ve ever sat in a hallway during a siren’s wail, you know that the safest place to be is down. But what if your entire lifestyle was built into the earth?
At OKC Underground House, we specialize in merging the ultimate in civil defense with modern, energy-efficient living. Whether you are looking to build a new monolithic unitized structure or need to save your existing home from the creeping dangers of foundation cracks, we are the local concrete experts you can trust.
Living in an earth house isn’t about moving into a dark, damp cave. Modern earth sheltered homes are architectural marvels. By using the natural thermal mass of the ground, these houses stay warm in the winter and cool during our blistering 100-degree summers. This makes them incredibly energy efficient, often reducing utility bills by up to 80% compared to traditional above-ground structures.
But the benefits go beyond the wallet. These are truly storm safe homes. A tornado resistant underground build offers a level of security that even the best safe room can’t match. Because the structure is earth bermed, the wind literally blows right over the top of you. For many of our clients, this peace of mind also leads to significant insurance breaks.

Not everyone is ready to move underground, but every Oklahoman has to deal with the soil we live on. Our state is famous for its expansive red clay, which acts like a sponge—swelling when wet and shrinking when dry. This constant movement leads to sloping floors, bowed walls, and those dreaded foundation cracks.
If you’ve noticed your doors sticking or gaps appearing in your brickwork, you likely need professional foundation repair. We offer specialized slab repair and slab lifting using state-of-the-art polyjacking services OKC homeowners rely on. Unlike old-fashioned mudjacking, polyjacking uses a high-density foam to provide a permanent, maintenance free solution for sinking concrete.
A sinking sidewalk or a cracked driveway isn’t just an eyesore; it’s a liability. Concrete leveling (or concrete slab leveling) is a fast, affordable way to fix sinking concrete without the mess of a full replacement. Our concrete driveway leveling process can have your surfaces ready for use in a matter of hours.

The biggest myth about underground homes or basements in Oklahoma is that they are destined to leak. With modern wall waterproofing and interior drainage systems, your home can remain bone-dry even during the heaviest spring deluges.
Waterproofing basement walls is a core part of what we do. If you are experiencing water in basement areas or noticing dampness, it’s vital to address it before mold takes hold. While the basement waterproofing cost varies depending on the severity of the issue, it is a fraction of the cost of structural repair once the damage spreads.

When we build underground homes, we use a monolithic unitized structure. This means the walls, floor, and roof are essentially one single piece of reinforced concrete. This creates a durable home construction that is virtually indestructible.
The cost typically ranges from $2,500 to $10,000 depending on whether you need exterior basement waterproofing or an interior drainage system. We provide a foundation repair estimate for free to help you plan your budget.
While no home is 100% maintenance-free, an earth bermed home has significantly fewer requirements. You won’t deal with roof leaks, exterior paint fading, or pest damage to the structure.
We drill small, penny-sized holes in your concrete and inject a specialized polymer. The foam expands, filling the void and providing a structural repair that levels the slab perfectly.
