Self-Adhering Waterproofing Membrane

Tarco introduces BG700, a self-adhering membrane for below-grade waterproofing applications. With a nominal thickness of 60 mils, BG700 includes two layers of waterproofing protection: an SBS-modified bituminous layer and a high-strength, cross-laminated, polyethylene facer.

The facer has exceptional tear resistance and waterproofing characteristics, while the mod bit layer meets the demands of a waterproofing membrane. The specially formulated rubberized asphalt compound yields a pliable sheet that self-seals around fasteners and will not crack or dry. This highly durable material can be used in a variety of applications. It adheres well to a wide range of substrates such as concrete, plywood, OSB, metal, wood, vinyl, masonry, and certain rigid insulations, insulated concrete forms (ICF) etc.

Besides the two layers of waterproofing, BG700 has a removable silicone treated release line on the bottom adhesive side.

“The waterproofing protection, strength and durability offered by BG700 is as good as it gets,” said Josh Bailey, Business Manager, Building Envelopes Products for Tarco.

The name BG700 suggests that this extraordinary membrane is suitable for “below grade” waterproofing applications and that is certainly true. However, it is also suitable for countless other waterproofing applications such as the following:

• Under siding, exterior plaster or wall flashing
• Vertical and horizontal waterproofing of foundation walls, tunnels, and earth shelters
• Plaza decks, balconies, terraces, and planters
• Wherever there is a need to resist hydrostatic pressure
• Strips can be used to patch cracks and repair leaks
• Interior applications in “wet areas” (such as utility rooms, bathrooms, and kitchens)

“Our goal is to create a product equal to or better than any product in the market today,” said David Snowden III, President of Tarco. “We have reached that goal with the BG700, a waterproofing membrane that is in a class of its own.”
