Here’s Why Oklahoma City Needs Underground Bunkers

Oklahoma is situated in the “alley of tornado” making it prone to strong hurricanes, tornadoes and twisters. Such natural disasters can cause a lot of damage and claim lives. Therefore, it is recommended to install underground bunkers in Oklahoma City. It is the safest option for the residents to protect themselves in case of natural calamities.

Here are some reasons why it is important to have underground bunkers in Oklahoma City.

1. It Can Be Custom-Made

Underground bunkers can be built according to your requirements and can fit all the members of your family safely. They’re built according to the FEMA guidelines providing sufficient space per person, giving special attention to each family member’s age and special requirements like wheelchair access.

2. You Can Stock Emergency Supplies in it

During a natural disaster, you get no warning to collect the essential items your need before heading to the shelter. An underground bunker can be stocked with all the emergency supplies you might need during an emergency. This includes bedding, food supplies, toiletries and medical supplies.

3. It Can Store Your Valuables

Besides necessities, you can store your documents, IDs, jewelry and other valuables in the underground bunker. In case of natural disasters, these underground bunkers prove to be safer and more convenient to access because banks can be hard to reach and your valuables can be destroyed.

4. It Is Easy to Access

4 Alternate Ways To Use A Storm Shelter In Norman, OK

Storm shelters are an inevitable investment you need to make, living in Norman. The frequent hurricanes and tornadoes demand protection and safety for your family. But is that all you can use a storm shelter for? Storm shelters can be useful besides just being used during storms. There are quite a few ways for you to utilize your storm shelter during the off-storm season.

Here are a few alternate ways for storm shelter uses in Norman.

1. Use It As a Personal Vault

One of the safest places in your house to keep all your valuables and precious belongings can be your storm shelter. It can act as an alternative to your bank locker. You can use it to keep important documents, cash, expensive artifacts or any other valuables you want to keep safe. This doesn’t only act as a protection against theft or robbery, but in case of flooding, the storm shelter can protect all your precious valuables and belongings.

2. Use It For Extra Storage

You can use your storm shelter for extra storage if you’re running low on space in your house. For example, if you run a small business from your home and have received a big order, you can use the shelter to store your inventory safely. It can also be used to keep extra furniture and other household items like mattresses and bedding that may be used occasionally.

3. Use It to Store Food

In Norman, we understand the extent of damage hurricanes and tornadoes can cause. It is always safer to be ready and stock non-perishable food items to prepare for such emergencies. You can use your storm shelter as a space to stock up on canned and non-perishable food items.

 4. Use It As A Guest Bedroom

Is It Important To Hire A Professional For Concrete Storm Shelter Installation?

Like many Americans, you might be tempted to attempt a DIY safe room or storm shelter installation in your home. But there are several reasons why that’s a bad idea, most of which have to do with your safety and that of your family in times of natural disasters.

This blog talks about why hiring an expert is necessary for your concrete storm shelter installation and where you can find reliable storm shelter experts in Norman and Oklahoma City.

1. Structural Integrity

For your storm shelter to withstand dangerous storms, it must have a sound structure. Hiring a professional for your concrete storm shelter installation will prove more beneficial as they’ll look into whether the walls, ceiling and floor can hold you and your family during a tornado or hurricane.

Our concrete storm shelters are incredibly strong and come with a 10-year warranty on leaks and corrosion. We’ll also do an inspection after the installation to ensure the structural integrity of your safe room.

2. Ventilation

Your storm shelter also requires a proper ventilation system to keep oxygen flowing in and out. Depending on whether your storm shelter is above-ground or underground, a storm shelter expert will ensure that your safe room receives ample fresh air for you and your family to safely ride out the storm.

Our experts can also support you in applying for your storm shelter permit so that you don’t miss any important documentation.

3. Security

Perhaps the most important reason you should hire a professional for your concrete storm shelter installation is to make sure that your shelter is fully secure. Some features that we add to our storm shelters for protection include steel doors with gas hinges and deadbolts, thick walls supported with a rebar cage, and have them pass the Texas Tech Impact Test, among several others.

Flat Top Vs. Slope Top: Which Type Of Shelter Works Best For You?

Storm shelters are necessary additions to homes across South America. If you’re a resident of Oklahoma City or Norman, your home should have a safe room installed to ensure your safety during a natural disaster.

So if you’re looking for the right shelter for your home, you should know that common varieties in safe rooms include flat-top vs slope-top shelters, both of which offer general benefits and advantages specific to their shapes. Read on to learn which of the two works better for you.

Flat Top Shelters

These shelters are typically installed in the ground, which means they can go either outside your home or in your garage, depending on how much space you’ve got. Because their tops are flat, they don’t obstruct anything, which is why you can install them in your garage and park your car on top.

Both our flat-top vs slope-top shelters come equipped with several useful features. These include gas hinges on a steel door, with pre-cast concrete and strengthened with mesh and rebar. For more information on our storm shelters, read through our FAQ page.

Slope Top Shelters

In several ways, flat-top vs slope-top shelters are almost identical in design and specifications. However, some differences might be relevant to some of you. The sloping top allows rainwater, snow, and other debris to slide right off the shelter’s top, as opposed to flat-top shelters.

The slope also makes it easier to spot the shelter from a distance, which would not be possible with a flat-top shelter in most cases. Our flat-top vs slope-top shelters offer 10 years’ worth of protection against leaks and corrosion and come with wind turbines to ensure ventilation. Finally, either of these storm shelters can be made to accommodate anywhere between 5 to 23 people.

3 Advantages Of Getting A Garage Storm Shelter

Do you have a garage with your home in Norman? If so, you might want to consider installing your new storm shelter there instead of having it set up right outside your house. Garage storm shelters are perhaps the quickest way you and your family can get to safety if a storm warning goes off.

Garage shelters, if installed properly, can also withstand tornadoes as deadly as those classified as EF5. Here are some advantages of installing a garage storm shelter on your property.

Quick To Access

Having a storm shelter on your property makes it much faster to get to safety. This is perhaps the biggest advantage of having your garage storm shelter, along with being an efficient way to utilize space in your home.

We offer several garage shelters for sale in Norman and Oklahoma City, quotes for which are provided completely free of cost. Learn more about our garage shelters and their specifications before making your decision.


Every home deserves a shelter built to keep their needs in mind. If there’s anyone in your family who uses a wheelchair, your garage storm shelter must be wheelchair-friendly. Similarly, grandparents who may struggle going up and down the stairs may require support from a staircase’s guardrail.

There are several ways to customize your garage storm shelter. We first conduct an assessment of your property and collect information about each family member to see what they’ll need to access the safe room. Then, we will share a final plan with you for approval before beginning the installation.

What Specifications Should My Steel Safe Room Have?

Safe rooms are common across South America, given how often it is ravaged by natural disasters like hurricanes and tornadoes. That’s why your Oklahoman home needs a reliable storm shelter since it sees storms almost all year round.

So if you plan on getting a steel safe room for your property, go through this blog to learn which features it should have for the safety of your family.

1. Accessibility

One of the major features your steel safe room should have is easy access for all your family members. This means that you might need your safe room to also be disability-friendly, meaning that people on wheelchairs can also access it as needed.

A good steel room would have a ramp that allows wheelchairs to go inside or a staircase if the shelter is installed underground. Lastly, your storm shelter should also be installed in an area of your home that everyone can reach quickly when a disaster warning is given by the authorities.

2. Security

Some necessary features that we think a steel safe room should have include deadbolts on the door, which should be secured with strong anchor bolts. The bolts that we use for our shelters are incredibly strong, with each one offering 10,000 lbs.

The entire structure of the storm shelter should be encased in steel, with the door at the thickest for maximum protection. We also ensure that all our shelters are deemed safe by authorities and pass the Texas Tech Impact Test.

3. Ventilation And Storage

Every storm shelter or safe room requires a fully functional ventilation system to keep everyone safe during a storm. That’s why our shelters have two large vents so that everyone can ride out the storm safely.

It’s also important for your safe room to have ample storage space where you can keep necessities, i.e., food, medical supplies, emergency radio, etc.

Three Indicators To Seek Shelter In A Safe Room

The state of Oklahoma experiences many tornadoes throughout the year, causing severe damage to wildlife and property. If you live in Oklahoma City or Norman, you’ve likely had to rush for shelter, whether in your home or to the community’s storm shelter.

In times of natural disasters, being well-prepared can determine your chances of survival. Therefore, paying attention to the signs of an impending disaster is extremely important. To help you plan your evacuation, here’s how you’ll know it’s time to seek shelter in a safe room.

Atmospheric Warnings

The most authentic way to know of an impending disaster – including tornadoes – is to watch out for any atmospheric signs. These can either be observed in person or delivered by relevant authorities via announcements. For authentic warnings, keep tabs on the National Weather Service’s website.

Read the following atmospheric warnings before seeking shelter in a safe room:

1. Sky Changing Color

Often when a tornado is about to arrive, the sky might turn a shade too green or just go dark. That’s a clear sign that you need to grab your pets (if any) and rush to the safe room with your family.

2. Debris-Carrying Clouds

Another sign of an impending tornado are clouds carrying debris. These might start small but often get bigger even if there is no funnel. Make sure to stay away from windows if you see debris flying around.

3. Calm Before The Chaos

Right before the tornado is about to strike, you’ll notice a stillness in the air. Treat this as an announcement of the disaster and stay inside your safe room until you’ve been informed it’s safe to go out.

Do Safe Rooms Offer More Protection Than Underground Shelters?

Are you a homeowner in Norman or Oklahoma City? You’ve probably encountered a few tornado warnings by now, which we understand can be quite anxiety-inducing for many residents. Given the climate of Oklahoma and nearby states, safe rooms and underground shelters are common additions for residential and commercial facilities.

But which of the two is safer? Find out in this contrast of safe rooms vs. underground shelters.

Safe Rooms

In the United States, safe rooms are designed to offer maximum protection against violent winds and storms while adhering to FEMA’s guidelines on constructing safe rooms. These are either made of concrete or steel, have heavy-duty doors, and can be built with insulation to regulate temperature.

Safe rooms are also useful in times of nuclear disasters, as their construction is done using materials that make it impenetrable, even for radioactive waste. However, all these features make safe rooms significantly more expensive to install.

Oklahoma Shelters offers steel and concrete safe rooms that can hold anywhere between 4 to 2 people, depending on the size you request. Connect with us for a free consultation on your property.

Underground Shelters

Unlike safe rooms, underground shelters and bunkers follow the guidelines of the ICC, specifically their NSSA 500 Standard for the Design and Construction of Storm Shelters. They are typically built within existing structures like garages or basements using lighter metals for quicker installation and fitting. However, lighter metals make for relatively-less safe shelters and lack temperature regulation as they aren’t usually insulated.

At Oklahoma Shelters, you’ll find both underground garage shelters and underground concrete or steel bunkers that follow the guidelines highlighted by relevant authorities. And what’s more, is that we use strong materials to make each for maximum protection against storms.

Still unsure about which safety mechanism is better for your home? You’ve got no reason to worry because Oklahoma Shelters can quickly assess your property and make recommendations accordingly. Call us at 405-367-7901 or leave an email at sales@sm.dev-version.com to get in touch.

All our safe rooms and underground shelters come with warranties, so you can rest assured knowing you’ve made a value-laden investment. For more information on our facilities and installation processes, read through our FAQ section.

Tornado Aftermath: Your Ultimate Survival Guide!

Hearing a tornado warning for the first time can be an overwhelming experience. That’s why having a plan of action is important because you don’t want to panic when an emergency strikes.

If you’re new to the state and aren’t yet accustomed to disaster warnings, this survival guide for tornadoes can help you and your family keep safe.

1. Stay Updated On Weather Conditions

The first thing you need to make a habit of is regularly checking weather predictions. Knowing when and where a tornado might hit is crucial to your safety plan, so this step cannot be ignored. To keep tabs on the weather, you can use the National Weather Service’s official website.

2. Have A Plan On Getting To Shelter

Next on this survival guide for tornadoes is an evacuation plan for you and your family members. If the storm shelter is above ground outside your house, you’ll probably need to factor in about 10 to 15 minutes to get inside. But if it’s a safe room installed within your home, i.e., an underground bunker in your garage, getting to safety can be faster.

To cut it short, once the warning hits, grab your family members and head to the shelter without wasting any time.

3. Keep Shelter Stocked With Necessities

Your storm shelter needs to have all necessities–food and water, emergency first aid, a communication device, warm clothing, etc. – already stocked well before the warning is announced. Because when the tornado hits, you might not have time to collect anything. So be prepared in advance to ride out the storm.

4. Use Radio To Call For Help

It always helps to have a communication device in your underground bunker to call people if you get separated from loved ones or require the help of evacuation authorities. We recommend that you keep a radio device to stay updated on the weather and communicate whenever necessary.

For residents of Norman and Oklahoma City, we have great news! Oklahoma Shelters offers free quotes on your residential facilities, so put in your details and schedule a visit. Our showroom has underground garage shelters and bunkers, concrete storm shelters, and safe rooms for you to choose from, which are installed following the safety guidelines by FEMA.

To stay safe during a tornado, you’ll need a well-built safe room in your home. Luckily, Oklahoma Shelters offers steel-safe rooms that can be built to hold up to 25-26 people. Call us directly or leave your details on our website to place an order.

The Three Advantages Of Having A Safe Room In Your House

Having a safe room in a house is mandatory in some districts of Oklahoma State, given how often it is hit by tornadoes. If you happen to live in any of these districts, you’ll need a service provider to install a storm-safe shelter at your home.

Safe rooms are necessary additions to homes in certain parts of the world where cyclones, hurricanes, and other natural disasters are frequent. Their job is to keep you and your loved ones safe from harm until the storm subsides. But storm shelters can also be used for other purposes.

Here are three advantages of having a safe room in your house.

An underground basement with food stored in barrels and some fruit baskets

1. Increases Storage Capacity

Besides the obvious benefit of saving your life from a life-threatening disaster, storm shelters can add to your home’s storage capacity. During a storm, it’ll be your haven, but the rest of the year, you can use it to store necessities like food, warm clothing and bedding, medical supplies, and anything that’ll fit inside.

2. Raises Property Value

When buying a family home, you’ll want to ensure that your investment brings good returns when the time comes. Having your home fitted with a concrete storm shelter will increase its property value, meaning that when you need to sell the property, you can get back what you invested into making the shelter or perhaps get even more!

3. Protects You In Case Of A Home Invasion

In times like these, you’ll probably want all the security you can get for your family. With storm shelters – either above ground or underground – you can stay safe from attacks on your home or family. Because our safe rooms come with door seals to safeguard you and your loved ones against dangerous winds, they will also protect you in case of a home invasion.

If you’d like a free quote on your home for an above-ground storm shelter in Oklahoma City or Norman, leave us your details, and we’ll coordinate a visit.

If you’ve recently moved to Oklahoma City or Norman with your family, make sure to have a safe room for your house or an underground bunker in your garage. The bunker should be installed in such a way that all your family members can quickly reach there in an emergency.

You should also get your bunker examined by experts before settling in. That’ll make sure your shelter is up to date on security standards and allow us to make any upgrades if necessary. To learn more about how we can keep your family safe during a bad storm, call 405-367-7901.
