What type of masonry installation consists of a masonry veneer secured with approved mechanical fasteners to an approved backing?

The correct answer is anchored masonry veneer. This type of masonry installation involves a veneer layer made of masonry materials like brick or stone that is fastened to a supporting structural backing using approved mechanical fasteners. This method allows the masonry to be secured against lateral forces and provides a degree of flexibility to accommodate movement, which is important in reducing the risk of cracking.

Anchored masonry veneer is distinct from other options like solid masonry, which is a method of constructing walls entirely out of brick or block without a backing, making it much heavier and not reliant on mechanical fasteners. Adhered masonry veneer involves bonding the masonry to the backing with mortar or adhesive rather than mechanical means, which is less resistant to certain types of forces. Precast masonry refers to concrete elements that are cast in a controlled environment and may not involve a veneer or the same fastening methods as anchored masonry veneer.

Understanding these distinctions is crucial for selecting the correct masonry installation method in construction projects, ensuring compliance with building codes and structural requirements.
