While authorities are still investigating the cause of the NYC incident, we know that bricks and particularly, mortar can deteriorate from years of water penetration. This picture demonstrates the effectiveness of Presto's LeachStop® on bricks and mortar which prevents penetration of water and the effects of the elements. The area in the center of the photo was treated with Leachstop® days before applying water to the brick wall. It is easy to see where the protected area prevents water from penetrating the brick and mortar. This not only helps prevent staining but preserves the integrity of the mortar that holds the brick in place. Protection is especially important during the winter months when water can enter the mortar, freeze, expand and crack causing the strength of the materials to be compromised.
Older constructed high-rise brick buildings should be inspected periodically to prevent a similar situation to the New York incident considering the liability of property owners and public safety. Call us at 1-800-693-1228 to discuss it or be of assistance.
