If your property is the middle of a drought or in the middle of a hurricane, the most secure place to find a refuge during an emergency is underground. There are many kinds of storm shelters that are available including small shelters for residential use to large emergency shelters that can be used in schools. And the most important thing is that these kinds of shelters are inexpensive, so you'll save lots of money.
Below-ground shelters are much easier to construct than above-ground storm shelters. The shelters are simply lowered into the hole, and then filled with concrete. If the weather is enough severe the lid is put on and the Shelter is bolted to the concrete slab. Since they're constructed in the ground, they're much safer than shelters that are above ground. You will not be concerned about the dampness of your roof or uncomfortable conditions.
There are underground shelters that you can put in your garage, in addition to above-ground storm shelters. This type of shelter is similar to other underground storm shelters, minus that it's installed under the garage. The only difference between above-ground shelters and underground shelters is that they are constructed of high-quality steel. They also must meet local codes and FEMA requirements. The best method to secure your home is to build your own storm shelter, but be sure you hire an expert and obtain the right permits before you begin.
