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…Read More

Once moisture enters the system, the roof insulation quickly deteriorates to a point where the roofing and insulation must be completely removed before the roof can be replaced. With timely intervention, it is possible to avoid the necessity of costly and disruptive roof removal.Read More
