A method includes providing a plurality of prefabricated parts for assembly, where the plurality of prefabricated parts comprises one or more rubber mats and a central core. The method also includes preparing one or more external surfaces of the central core, applying a sealer to the one or more external surfaces of the central core, applying a bonding agent primer and a top coat to the one or more external surfaces of the central core, and pressing the one or more rubber mats to the one or more external surfaces of the central core. The method further includes applying a constant pressure to the one or more rubber mats and the central core, where a combination of the one or more rubber mats and the central core forms a blast and ballistic resistance wall.
