FREQUENT MASONRY PROBLEMS

JAGGED JOINTS

CAUSES

Over time, brick walls are subject to various constraints such as salt, pollutants, temperature differences, the freeze-thaw cycle which can significantly affect their behavior. Consequences of these constraints, the mortar disintegrates and crumbles, becomes sandy and loses its waterproofness. Water infiltrates behind the brick siding and when there is frost, corrodes and breaks the anchors, causing the bricks to move and creating significant structural problems.

CONSEQUENCES

The mortar crumbles and falls at the front and back of the wall.

SOLUTION

• In the case of a mortar in good condition: Empty and add mortar on top of the old one to stop the deterioration of the joints.
• In the case of a mortar in poor condition: Dismantle the wall and rebuild the damaged section.

TO NOTE

Assessing the condition of the mortar between the bricks is essential. If the assessment is not adequate, placing new mortar on mortar in poor condition will make the problem worse! The majority of our customers notice the crumbling of their joints. On the other hand, it is rare that the solution is as simple as joining. There is a popular belief that water seeps through the joints. This belief is false, since water has a greater tendency to infiltrate through the porosity of the brick than through the mortar joint.
