Masonry Construction utilizes pre-fabricated modular concrete or fired clay blocks assembled in the field to create walls. Masonry walls are usually reinforced to resist lateral loads due to wind and seismic requirements. Masonry walls can span vertically 22 to 30 feet depending on thickness and reinforcing. Masonry walls are typically used for schools, jails, hotels and low rise retail structures. Masonry walls are strong, durable and low maintenance in addition they have good fire rating and low sound transmission.
