Black Pearl®
COLD APPLIED ASPHALT BUILT-UP ROOFING & WATERPROOFING SYSTEM
DESCRIPTION
Unlike “weatherproofing”, a true waterproofing membrane will maintain its watertight integrity and prevent the passage of liquid under dynamic, static, continuous, or intermittent hydrostatic pressure.
Black Pearl® is a true waterproofing membrane.
Tenaciously adhered Black Pearl® waterproofing also prevents the passage of liquid water between the membrane and concrete substrates, even under 250 pounds per square inch of hydrostatic pressure. Black Pearl® also resists deterioration from common identified chemical exposure and resists root penetration. Offered with long term warranties assuring it will perform its waterproofing function, Black Pearl® is backed by the first name in American commercial moisture protection, The Barrett Company.
