What is the durability of brick?

What is the most durable brick?
The grade and type of clay masonry units are defined in ASTM C 62, C 216, and C 652. Grade SW (or severe weathering) is the most durable classification of brick. Grade MW units are less durable and can be used for face brick in parts of the country where the weathering index is not as severe.
What are the three durability designations for brick?
There are three factors that help determine brick durability: compressive strength, water absorption, and the saturation coefficient. The Brick Industry Association has more information about these factors in Technical Note 9A: specifications for and Classification of Brick.
Are there different grades of brick?
There are three grades of brick to choose from: Severe Weathering (SW): Able to experience freeze and thaw cycles; perfect for cold climates. Moderate Weathering (MW): Tolerance to frost and freezing; used for outdoor walls. No Weathering (NW): For indoor use only.

In short, bricks and mortar aren’t 100% waterproof. Even modern homes that are built with cavity walls and largely impermeable materials can still be affected by penetrating damp (water coming in from outside).
