As the superior vapor barrier, Barrier-Bac prevents mold from entering slabs, reducing the health risks to those at home or working in the building. The barrier also saves money for homeowners or property managers in the long run by reducing or eliminating the cost of mold remediation later.
Our Barrier-Bac Composite products provide a mechanical bond with concrete through the extra lamination of our geo-textile fabric. When concrete is poured over the composite vapor barrier, the geo-textile lamination adheres to the concrete to prevent pocketing.
Pocketing occurs when soil settlement allows water to migrate between a standard smooth surface vapor barrier and the concrete slab, creating pools of water directly in contact with the slab. Because of the mechanical bond and excellent peel adhesion of Barrier-Bac composite product, pocketing cannot occur. Contractors find this most valuable for projects with a high water table, void-formed slab, or expansive soil conditions.
VBC-90 is a cross-laminated polyethylene membrane laminated with a nonwoven polypropylene geotextile. The composite is tough, durable and can withstand harsh construction environments. Compared to paper floor protection, the polypropylene fibers do not absorb the stain from decorative concrete and do not scratch wood, tile or other finished floor systems. The fuzzy fibers also provide room for more air circulation. Water will not deteriorate VBC-90 like it will paper floor protection.
Barrier-Bac also acts as a vapor barrier against Radon, Methane and other harmful gases. It works together with your ventilation system to add a level of protection to your building from these gases. Barrier-Bac vapor barrier also acts as a physical barrier that reduces the risk of termite infestation.
