mortared

Mortared is a term used in construction and masonry to describe units of masonry—such as bricks, stones, or concrete blocks—that are bonded together with mortar. Mortar is a binding material, typically a mixture of cement or lime, sand, and water, which fills joints and secures individual units in place. When masonry is described as mortared, it implies that the bonding material has been applied and joints have been finished to create a continuous, load-bearing or non-load-bearing wall or structure.

The word derives from mortar, the binding substance used in masonry. In historical contexts, mortared masonry often employed lime-based mortars, sometimes with additions like pozzolanic materials. Modern practice commonly uses cement-based mortars, either reinforced with Portland cement or combined with lime for compatibility with traditional materials. The choice of mortar affects workability, strength, breathability, and the movement of moisture within the wall.

In practice, mortared masonry involves laying units with joints filled by mortar and later finishing the joints through a process called pointing or repointing. Proper mortar selection is important for durability and for preserving historic fabric, as incompatible mortars can cause deterioration. In restoration work, lime mortars are favored for older buildings due to their flexibility and moisture transfer properties.

Overall, mortared masonry remains a fundamental method for constructing and repairing walls, with material choices tailored to the structural and environmental requirements of the project.
