A portable molding apparatus includes a lower portion including an extension device that is movable between an extended position and a retracted position, and a platform coupled to the extension device, an upper portion positioned above the lower portion, the upper portion including a base, a plurality of walls extending upward from the base, the plurality of walls defining a cavity bounded by the plurality of walls and the base, and a lid positioned over the cavity, a core positioned within the cavity defined by the plurality of walls, and a pin coupled to the core and extending downward from the core through the base, where the pin is spaced apart from the platform when the extension device is in the retracted position and the pin is engaged with the platform when the extension device is in the extended position.

A bullet resistant wall system including ballistic paver blocks constructed, configured, and arranged to form a wall having at least two adjacent individual layers. The at least two adjacent individual layers include multiple adjacent rows of the ballistic paver blocks. The ballistic paver blocks are formed from wet ballistic concrete prepared without an addition of a preformed foam or wet ballistic concrete prepared without an addition of a stabilizing agent.

A bunker system for shielding radiation emitted from a radiation treatment device includes a multi-core wall structure that completely surrounds the radiation treatment device. The wall structure includes a cast-in-place concrete inner core of limited thickness in order to minimize curing time requirements. The inner core is immediately surrounded by an outer core constructed from a plurality of preformed modular blocks. Each modular block is constructed of a radiation shielding material, such as concrete. As part of the assembly process, the preformed modular blocks are designed to be stacked top-to-bottom and side-by-side in an interlocking fashion to form a continuous wall structure, with blocks additionally arranged in a front-to-back relationship to achieve the required outer core thickness. The dual-core construction of the wall structure enables the bunker system to be quickly and efficiently assembled with enhanced quality control and potential reusability.
