Rising S Bunkers offers the best underground steel shelters, bomb shelters, safe rooms & blast doors on the market. We lead the industry in quality and we have the highest standards for craftsmanship in underground bunkers and other emergency shelters. The Rising S standard of quality is unmatched by any other bunker company on the market today. Additionally, every project is completely customizable. Many customization's are available at no additional cost.

"Not even sure where to begin with this nightmare which I will now need to spend more money in legal just to get my money back if I'm lucky. It all started back in 2022 when a respectful salesperson Gary sold me on an underground bunker. Still to this day, he answers the phone for me, and he doesn't even work at Rising S company anymore. To keep a long story shorter, I paid over $100K for my unit after being pushed to make payments to 'keep it on the assembly line'. It has been paid in full since August of 2023 (just about 15 months for anyone counting). I received a response (finally) earlier this year in March that there is new ownership of the company, and the man in charge is Brad Dancer. After trying to contact for quite awhile, I did finally get him on the phone. He apologized and explained to me that he's in over his head. Even though I believe I have been more than patient, I agreed to give him some time to finish and deliver my unit. We agreed that August of this year (2024) I would have it. I checked in by email in June to ask if we were still on track. I received a response that we were indeed on track. Now fast forward to today (10/25/24), I have been completely ghosted by email, phone, and text. No responses at all by ANY form of communication. At this point, I realize I have been robbed of over $100K. And after reading many other consumers reviews on different platforms, it appears I'm not the only one. I will now begin my journey with the Attorney General and Legal process. I'll update my status here so anyone can see what happens. At least people can get answers some way. It is not a good feeling to not be able to get a company to call you, especially after they've taken over $100k. You can't even leave a message on the office line ( which no one has EVER answered by the way). I don't understand how a company like this could still be in business. My recommendation to anyone reading this.....I hope it's not too late for you."

Concrete Walls questions, answered by experts

Aim for a concrete thickness of at least 4 inches for the walls of your above-ground storm shelter and 3.0 to 3.5 cubic yards of concrete for the base of your storm shelter. If you’re concerned about the thickness of your concrete while building a storm shelter, get in touch with a professional storm shelter builder to make sure your work is up to code and safe. 

Generally, a wall can bow up to 30% of its thickness, or around 2.5 inches for an 8-inch-thick structure, before it becomes an urgent situation. If your basement wall bows more than 1 inch, it's time to have a basement inspection to determine if a repair is necessary, depending on the soil conditions and structural specifics. Walls nearing 4 inches of bowing will require significant repairs. More than 6 inches of bowing usually means the wall will need replacing.

Unfortunately, concrete cracks happen, so there’s no surefire way to avoid them long-term. To slow down the cracking, apply a sealant every two to three years and use sand rather than salt to melt snow or ice. Using salt speeds up the freeze-thaw cycle, which may increase the likelihood of cracking. Additionally, keep vehicles and heavy machinery off of your concrete, as the weight can lead to more cracking.

Yes, thicker concrete is less likely to crack. The thicker the concrete is, the less susceptible it is to extreme changes in weather conditions that often cause concrete to crack or chip. If you’re unable to install a thicker concrete driveway for any reason, you can also ask your professional to install more rebar or wire mesh to provide greater strength and better resilience to damage.

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.
