UNDERGROUND HIGH-TECH SHELTERS FOR MAXIMUM PROTECTION AND SURVIVAL Prefabricated units all-included packages: each module is prefabricated in controlled environment with quality control at our shop. To be delivered on site with standard trucking equipment no need for any oversize transportation permit. Fast and doesn’t attract unnecessary attention. Noninvasive pier-based foundations: we don’t pour concrete on site. This leads to faster installation, a cleaner construction process, and less settlements. Our piles don’t affect existing structures and can be installed adjacent to the existing buildings. Two days installation. We excavate the pit and drive piles on day one, install units, and backfill on day two.
