One can easily spot the signs of a leaking mortar joint. The following are the signs to look out for:
Some blocks or bricks may have a wet appearance, particularly around the mortar
If some bricks seem to be wearing out faster than the rest of the wall, then this is a sign of a point of entry. The mortar could possibly be deteriorating on some bricks.
Water stains may appear on the inside walls, and further examination may show that the water came through the mortar
Water can trace its path through the mortar, and eventually running the walls down and emerging in the basement. If there are puddles beneath the wet bricks, then there exists a bad leak that is undoubtedly related to the mortar joint.
If your property has a block for a wall, it can be more challenging to identify the problem. In such a case, water can seep through the mortar, reach the hollows of the brick and appear inside the home many feet away from the actual entry point.
There are many reasons for mortar joint leaks. Mortar can basically wear out over time, particularly when exposed to harsh conditions and weathered. Poor construction may also contribute to quicker deterioration of the mortar especially when bad quality materials are used or if they are laid too thin.
Essentially, if water floods in your home or the exterior walls are assaulted due to heavy rains, water will flow with less resistance. This could possibly be through the brick itself, or through the mortar. Water always finds a path. This is the reason why it is imperative to install the appropriate waterproofing and drainage systems to inhibit water from tracing a path through your mortar and walls and eventually into your home.
