Why does my masonry wall crack?
Masonry walls, whether built of stone, brick or cement, all absorb moisture and react to stresses due to their weight and age. When inferior or inappropriate materials compound these factors, you may end up with a mess of peeling, popping and cracking mortar or masonry. Accurate diagnosis of the cause of your wall’s deterioration should guide your plan to cure it.
What causes cracks in cement walls?
Settling results from shifting soil underneath the wall and causes vertical or diagonal cracks and spalling. Many cracks due to settling are unattractive but structurally insignificant, but a professional engineer can diagnose whether the wall needs reinforcement before mending. Peeling in cement, concrete and mortar mixtures that have not been formulated to meet loading, creep or pressure differentials may need professional repair rather than resurfacing.

For whole wall or large area restoration, mix a sanded cement, called parge, to cover spalls or discolorations, or moisture damage. Clean the area well with a wire brush or low-pressure steamer, and wet the area with a hose or sprayer to keep the dry masonry from soaking water in, causing the parge to cure too fast.

Can You Mortar Over Old Mortar?
If your brick is 50 years old or less, you can probably repoint it safely with modern, portland cement–based mortar (although the guy doing the next repointing, who'll have to grind it out, may curse your decision). But if your house was built before World War II, the mortar is likely a mix of lime putty and sand, and you should try to match it. Otherwise, over time, as the soft old brick swells and shrinks against the rock-hard mortar, the bond between them will break, moisture will get trapped in the wall, and the brick faces will start popping off. Traditional lime mortar acts like a cushion, flexing with the brick's movement while allowing moisture to migrate easily out of the wall.

How are the wythes separated in a cavity wall?

How to inspect a wall for bulges?
The simplest method is to sight down the face of the wall with one eye, studying the surface for bulges. Another approach is to look inside the wall cavity with a borescope, an inspection device consisting of long rigid or flexible tube with a lens at the end. After boring a small hole in a mortar joint, an engineer can insert the borescope and look behind the veneer bricks to examine the cavity and the condition of tie bricks or metal ties.
Why do bricks crack in the winter?
Environment took its toll too. “Denver’s sunny days and cold nights are the real culprits,” notes Diane Travis, technical advisor of the Rocky Mountain Masonry Institute, a nonprofit organization whose mission is to increase understanding and use of masonry. “When it rains or snows, brick becomes saturated,” she explains, “Then the water expands 9 percent when it freezes.” The constant freezing and thawing, called freeze-thaw cycles, can fracture even tough materials like brick, block, or stone. Once the outer wythe of brick starts tearing away from the inner wythes, it creates a vertical crack between the layers of the wall. “Broken brick accumulates in these fractures,” adds Travis, “and this debris forces the crack to get wider and wider.” Houses in climates where there are significant temperature swings might also be subject to this damage.
What is the condition called when bricks are separating from the bricks behind them?
