Welcome to In ground Safe Room!

Severe weather is notoriously unpredictable. We have a vast knowledge about the conditions and surroundings that cause it and how often this occurs throughout the country. We have sophisticated warning systems, as well as extensive radio and 24/7 news and television coverage of these storms and Tornadoes as they approach and even destroy. Even with all of this technology and warning systems, still hundreds are killed each year from tornadoes, freak storms and other disasters, with thousands more injured. Property loss and damage is routinely in the billions of dollars. Help protect your family today with an investment into your families lives by keeping them safe from tornadoes and tornado destruction with an In ground Safe Room Tornado Shelter by Granger Plastics!

Every home should have a safe room for families to use in case of emergency. But if you home or business is located in an area known for sever storms and tornadoes, an interior room may not be enough to survive uninjured. This is especially true for manufactured homes and buildings, or any structure without access to a basement or a below ground level. Whether you live in a populated area or a remote location, there are many possible emergencies, disaster situations or local conditions in which you and your family would just feel safer in a protected place that is inaccessible to others and nearly indestructible to the elements.

Safe Room Tornado Risk Map, Tornado Shelter, Granger ISS, Tornado Risk Map

As you can see from the graphic above, the entire United States is at risk of Tornadoes. A smaller group of Western-most states are only likely to see Tornadoes up to 130 mph, but the over whelming majority of states could see Tornado wind speed, typically 160 mph or faster. While a large, centralized population could see Tornado wind speeds in the 200-250 mph range! In 2010 alone, we have seen a number of Tornadoes strike unusual areas for Tornadoes to hit, including New York City, Phoenix, Washington D.C., Connecticut and more!

Many people well tell you from personal experiences, tornadoes can cause true devastation. Tornadoes are well known for home destruction, as well as demolishing some of the strongest structures know to man. They throw trees and cars, down dangerous power lines and pick nearly anything up that crosses its path. As most safety experts will tell you, in a time of heavy storms and tornadoes, below ground in a safety shelter or a safe room is the safest place to be.

Tornadoes are measured in the "Fujita Scale" (or F-Scale). Commonly referred to as an "F1, F2, F3, etc.", the scale rates Tornadoes on intensity, based on the damage that is inflicted upon human-built structures and vegetation. The official scale is determined by meteorologists and engineers after a ground and/or aerial damage survey; contingent upon the circumstances, ground swirl patterns (cycloidal marks), radar tracking, eye witness statements, media reports and damage imagery, as well as photogrammetry/videogrammetry if motion picture recording is available. Even though each Fujita Scale damage level is associated with a speed of wind (mph), the Fujita scale is a damage scale and the wind speeds that are associated with the damage listed are unverified. Listed below are the Fujita categories of Tornadoes and their associated, estimated wind speeds.

F Number Fastest 1/4-mile (mph) 3 Second Gust (mph)
0 40-72 45-78
1 73-112 79-117
2 113-157 118-161
3 158-207 162-209
4 208-260 210-261
5 261-318 262-317

The extremely durable, innovative, polymer construction of the Inground Safe Room Tornado Shelter can provide a useful life span that under most conditions should exceed 500 years! Unlike concrete, steel and fiberglass In ground Safe Room Tornado and Storm Shelters, the Polyethylene construction won't deteriorate, alleviating concerns and maintenance issues that apply to other materials. Concrete safe rooms tend to settle and form cracks throughout the unit. With fiberglass safe rooms and shelters, moisture is a problem causing the unit to crack, deteriorate and/or possibly rot. Unlike Steel units, the In ground Safe Room Tornado Shelter will not rust or corrode. The extremely thick 1/2" double wall construction, offers not only the extreme strength of a rotationally molded product, but offers a wall thickness combination that exceeds most single wall units.
