GSA Specified Product
U.S. Patented System
Explore Weathercap's patented masonry joint protection systems. Designed for belt courses, cornices, and coping, our soft lead flashing flexes with building movement to create a permanent, leak-free seal. Ideal for historic preservation and new construction, it extends sealant life and prevents moisture penetration in critical masonry joints.


While we specialize in masonry joint protection, for concrete finishing, professionals often prefer leather or durable nylon tool belts. Look for belts with wide pouch openings for easy access to trowels, edgers, and jointers, and reinforced stitching to handle the weight and abrasive nature of concrete tools.
