Most of the time, masonry contractors are told to put cavity flashing on their work. Flashing acts as a barrier that keeps water from getting into the building and sends it back out the wall. Cavity flashings are often necessary where the downward flow of water within the wall would be hindered or halted.
Flashings are also utilised under masonry copings, sills, and other horizontal surfaces. The type of material used will directly affect how long the flashing will last, especially in places where it will be exposed to sunlight or weather.
Cavity flashing needs a way for water to drain out of the wall, and this is usually done with weep holes or head joint vents at horizontal ends. The weeps should be put right above the flashing and go to the masonry drainage plane.
Putting vents at the top of a drainage cavity helps airflow behind the masonry, which shortens the time it takes to dry and reduces the chance of efflorescence.
Cavity flashing is meant to securely absorb moisture and divert it through weep holes and other openings toward the exterior. However, due to everyday exposure to different weather conditions, it will deteriorate eventually.
Moisture might travel inside the structure if the flashing is missing, broken, or improperly built, causing water damage, mould development, and structural issues.
