What is the correct approach when installing brick veneer on a wall?

When installing brick veneer on a wall, several crucial considerations must be met to ensure the structural integrity and longevity of the installation. Leaving a specified air space, such as 25 mm, is essential as it helps to manage moisture that might get behind the brick veneer. This air space facilitates drainage and ventilation, which can prevent issues like mold growth or damage caused by water trapped within the wall assembly.

Additionally, incorporating weeping holes is a best practice that allows any moisture that does enter the air space to escape. This drainage prevents water accumulation that could lead to significant damage over time. Regularly placed weep holes are vital and are typically positioned above the flashing.

Flashing is also an important component; it is installed to direct water away from vulnerable areas of the wall assembly. A proper installation requires that flashing extend a certain distance up the wall, generally more than 150 mm, to effectively channel water without fail.

This collective approach, encompassing all the practices, ensures that the brick veneer is installed correctly, safeguarding against moisture-related issues while enhancing the durability of the overall structure. Thus, recognizing the need for weeping holes, maintaining an adequate air space, and ensuring correct flashing installation are all integral to the process of installing brick veneer effectively.
