What consists of layers of impervious material to seal out moisture in masonry construction?

The concept of using layers of impervious material to seal out moisture in masonry construction is best exemplified by the idea of a vapor barrier. A vapor barrier is specifically designed to prevent moisture from penetrating through walls, ceilings, or floors, which is crucial in maintaining the integrity and durability of masonry structures. It acts as a barrier to water vapor, ensuring that moisture does not condense within the building materials, thereby preventing damage such as mold growth and structural deterioration.

In masonry construction, it is essential to create a protective layer that effectively stops moisture from the outside environment from entering the building. This is where you find various materials employed, such as polyethylene sheeting or rubberized membranes, which serve as a vapor barrier. These materials are strategically placed to control moisture levels and safeguard the structure against the adverse effects of water infiltration.

Flashing, while also a moisture control method, typically refers to the components installed to direct water away from critical areas, like intersections of roof planes and vertical surfaces. Sealing tape can be useful in certain applications to seal joints and seams but does not function as a comprehensive moisture barrier on its own. Weatherproofing refers more broadly to techniques used to protect structures from the elements rather than being a specific impervious layer.
