To provide maximum resistance to explosions, this Blast Window Retention Anchor System offers a customized solution for each application and masonry substrate. The system is a steel bar enclosed in a mesh fabric sleeve that is inserted into the masonry and connected to the blast window frame. A cementitious grout is then injected into the sleeve to fuse with the mesh, expand, and shape itself around the steel to fit the space. Load testing has proven that large blast loads can be successfully resisted in all types of masonry. Cintec.
