A method for retrofitting a preexisting wall to include bullet resistance. The retrofitted wall incorporates ballistic paver blocks that are capable of augmenting either an interior or exterior wall. The flexibility gained by using ballistic paver blocks affords cost and weight savings over traditional concrete, or alternatively, metal shielding.

The present invention relates to a projectile arresting device comprising a foundation constituting a floor, a rear wall and partition walls extending in a direction substantially perpendicular to the rear wall. The partition walls comprises a rear edge, adjacent the rear wall, and a front edge. Projectile stopping material is arranged between the partition walls. A projectile stopping material retaining front layer is disposed between the front edges of the partition walls and arranged adjacent the projectile stopping material. The front layer has a convex shape. The invention also relates to a method for preparing a projectile arresting device.

A slat arrangement for redirecting the trajectory of a bullet has a plurality of elongated steel slats, and each elongated steel slat has a longitudinal front edge and a longitudinal back edge stretching between a first end and a second end. The steel slats are positioned in a louver-like fashion for changing the direction of a bullet following a trajectory along the normal of the slat arrangement. A support structure is connected to each steel slat at the back edge of the steel slat, between the first end and the second end of the steel slat.
