Protective Buildings

Originally developed as a proposal for sheltering U.S. military aircraft, PBSI structures are designed to protect people and equipment. Whether you need absolute protection for a $10M Lear Jet, a $5M Ferrari collection, a $700K RV, irreplacable artwork, sensitive records, sentimental heirlooms, or all of the above – there is no equal to the protection and security provided by an EARTH SHELTER PROTECTIVE STRUCTURE!

Build to your desires

Your EARTH SHELTER PROTECTIVE STRUCTURE (ESPS) can be built to your requirements as a custom vault for your valuables. Divide it into seperate secure areas for your automobiles, wine collection, and so forth. Add an office or workout area above your muscle car collection. Devote some space for your Stradivarius. An ESPS provides a constant temperature environment that also allows for easy humidity control.

Don’t mar your beautiful estate with a large metal building for your RV – an ESPS can blend naturally into the landscape. You may have any kind of facade on the front to beautify or camouflage the structure.

ESPS are very resistant to damage from fires

Unlike a conventional building, an ESPS has no combustible roof and fewer exposed external walls. Thus, an ESPS is much less likely to suffer damage in a forest or brush fire than a conventional building.

ESPS are very resistant to extreme weather

Violent weather has no effect on any part of an ESPS except for windows and the exposed entry walls, which can be protected by storm shutters or other devices. Nothing will freeze, even if left for months unheated.

Don’t let this happen to you!

ESPS are very resistant to earthquakes
Our buildings have withstood numerous earthquakes in California and Idaho with no damage even though buildings around them were damaged. In fact, ESPS are very resistant to earthquakes.

ESPS, when built for maximum protection, provide

In the late 1980’s, one of our designs was involved in a government blast test. The ESPS, which was located 600 feet from the center of the blast, experienced no damage from a bomb equal to the size of the Hiroshima atomic bomb. Since then, we built a shelter complex in Montana designed to house approximately 2,000 people. This complex is capable of withstanding an 8.5 magnitude earthquake and a 1-megaton air burst at ground zero.

In summary, our buildings are well protected against extreme temperatures, wind, tornadoes, fire and other natural disasters, as well as man-made threats. In addition to increased protection and security, PBSI structures offer significant savings on utilities and maintenance – while providing a beautiful, light, comfortable and spacious environment.

An ESPS can be built quickly and can provide many levels of protection. ESPS come in a variety of standard widths and lengths. Additionally, PBSI can meet your custom specifications.
