Guardian Modular Vault Panels are poured using new developments in ultra high strength concrete technology. The 6” thick high strength Class I Guardian Panels provide the same strength as standard 12” thick reinforced concrete panels, but require much less space. Materials are continuously tested to insure consistency in quality. Guardian Modular Panels are 36″ to 40″ wide with heavy gauge weld plates for complete weld integrity. The ideal solution where space is limited, modular panels are available in Class M, 1, II and Class III.
