Traditional masonry mortar is categorized into three primary performance types based on compressive strength and application: Type S, Type N, and Type M. Type S mortar offers high bond and compressive strength, making it ideal for below-grade foundations, retaining walls, and heavy-duty load-bearing brickwork. Type N mortar provides medium strength and excellent workability, making it the industry standard for general above-grade exterior walls, chimneys, and tuckpointing. Type M mortar is the strongest formulation, designed primarily for heavy structural engineering, industrial chimneys, and high-pressure foundations, though it offers less flexibility than Type S or N options.
