Maçonnerie CB intervenes on all types of masonry work and to familiarize you with our world. We invite you to go through some definitions related to the field of masonry:

Weep hole

Weep hole

Also known as vents, weep holes promote proper air circulation behind your wall. It prevents mould from growing on the inside of wooden fences. Weep holes should be spaced 3 or 4 bricks apart, depending on the type of block used.

brick wall


The gap is the space between your existing wooden wall and the masonry wall (brick, stone, or concrete blocks). This space allows us to build a wall that is straight and adequately ventilated.

Efflorescence brick wall


Efflorescence is a deposit that frequently forms at the base of a wall or under a windowsill. This phenomenon is caused by minerals in the cement components, which emerge from the masonry units when they are exposed to humidity (i.e., rain or condensation vapours). It creates whitish, salty looking stains.


Buckling (ventre de boeuf)

The term buckling refers to the swelling of a brick, stone or concrete block wall. If the swelling is nominal, the wall can be easily repaired by removing the bricks, cleaning them, and then rebuilding the affected section using the same bricks, new mortar, galvanized anchors and a Tyvek® vapour barrier. If the bricks are excessively damaged, they can be replaced with similar new bricks.

If the swelling is excessive, there could be a risk of collapse or water infiltration. In this case, it may be necessary to use heavy equipment to demolish the wall safely, and to rebuild it.

wall tie

Wall tie

A wall tie is a strip of ribbed metal that is meant to be fastened to the existing wooden wall so that it can be attached to the masonry wall. Wall ties need to be galvanized to prevent rust and buckling.



Flashing is a membrane that is installed at the base of the interior wall and on the corner irons (angle irons) of doors and windows. Flashing should be of high quality, ideally made of a self-adhesive membrane (i.e., Blueskin®, Resist-0 or Soprema). A high-quality layer used along with plastic vents (weep holes) will ensure adequate wall ventilation, thus preventing the appearance of humidity inside the wall.
