Abstract

Methods, systems, and devices for installing barriers in openings of gaps in or between structures such as walls, ceilings, and floors are described herein. At least one barrier molding bag is positioned in the hole or gap, and a flowable firestop material that is preferably operative to cure or harden, such as a hydratable cementitious slurry, is introduced into the bag to create a barrier in the hole or gap.
