When a structure is subjected to a blast wave resulting from an accidental or intentional explosion on the outside of the building, the skin of the building is subjected to extreme high pressures that may blow the exterior and windows into the occupied spaces of the building. During these events, the building elements can become deadly shrapnel and increase the damage of such event. Cable Catchment systems are Engineered Blast Mitigation systems that are designed to limit the consequences of a blast. This is done by limiting the size and amount of elements that are susceptible to being propelled into the occupied space.

A catchment system is made of cables pitched to limit the size of the potentially projected façade elements and can be combined with a steel mesh to create a net that can catch blocks and large debris while allowing the energy and limitation of forces applied to the building frame/structure to dissipate. The main advantage of such an application is the fact that it makes existing façade and window systems (including historical structures) safer without replacement or an upgrade. Using high strength materials and hardware derived from its vehicular restraint systems, BCSI can design and implement Cable Catchment Systems adapted to each specific structure and client need
