Hepa Vacuum, which, like the Microtrap, filters out the smallest of particles. The containment, which consists of two layers of thick plastic which are placed on all walls and floors, will then be constructed. All plastic seams are then sealed with duct tape. When the containment is completed, the microtrap's negative pressure is checked and then actual asbestos removal begins. All Asbestos material is wetted down with amended water, which helps to minimize the chance that asbestos fibers will become airborne.
