Proper ground clearance and flashing are essential at all intersections to prevent damage, such as from efflorescence. Best Practices & Innovations

The Masonry Veneer Manufacturers Association (MVMA), often in collaboration with the National Concrete Masonry Association (NCMA) , provides industry-standard guidelines to ensure the quality, safety, and durability of adhered manufactured stone veneer (AMSV). Their primary guiding document is the "Installation Guide and Detailing Options for Compliance with ASTM C1780."
