Vertical-Articulation/Control/Expansion Joints allow controlled movement in masonry effectively to mitigate the occurrence of cracking and other linked defects.

They are now required to be installed in all un-reinforced (meaning constructs such as brick veneer house walls or standalone brick fences) masonry walls; except on land with certain soil classifications (determined by lab-testing and a structural engineer’s report).

Movement may occur due to material shrinkage, material expansion or earth movement. In general, these changes are brought on by climate or temperature/ thermal variations over a building structures lifetime. The articulation joints accommodate these movements in the building.

Expansion joints are not simply empty voids between individually built brick structures. Expansion-ties are built into the mortar beds to connect each structure. The expansion joints are then sealed with caulk (flexible silicone based product) that matches the colour of the masonry.

We cut and install expansion joints, including mortar matched expansion-tie installation and caulking to seal. In this example, Brick Repairs cut & installed expansion joints around a townhouse in Knoxfield. First photo is the fresh vertical wet-saw cut and then the final result.

I can highly recommend Brick Repairs as they did a neat job and helped us out under time critical circumstances.
