It is not uncommon for people to try and use fillers to patch up cracked bricks, but this won’t necessarily do the trick and cracks could very well continue to surface. That’s because the cause of the crack is not addressed by simply filling in the fissures. It’s important to ensure there are no serious structural issues impacting the structure.

Cracked bricks: What are the causes?

There are many factors that can result in cracked bricks, including:

  • Ignoring mortar damage. It is possible to repair cracked mortar with a simple process called repointing. Cracked bricks indicate that the damage has reached beyond the mortar. Bricks are more difficult to repair than crumbling mortar, but it is much easier to fix mortar damage if bricks are not treated quickly.
  • Internal or external pressure
  • Water damage
  • Leaks, or any point(s) where water can get in
  • Thermal expansion. The wall expands when it is exposed to the sun. This expansion can lead to cracks.
  • Freeze and thaw cycles. The wall can crack if it is subject to pressure from temperature fluctuations between hot/cold. The wall’s water can freeze and then thaw, which puts a lot of pressure on the bricks. This pressure eventually causes cracks.
  • Bricks can be cracked by vines or other leaf. The vines can be pulled on and caused to crack the bricks surrounding them. The bricks are more sensitive to moisture from the greenery, which adds additional moisture.
  • Foundation problems: Bricks can crack if the foundation isn’t in place.

Brick Crack Patterns: How To Know If Your Cracked Bricks Signal Foundation Issues

Is just one brick cracked? Do you notice cracking bricks along a single wall? The type of damage you are observing will be determined by your answer.

Horizontal Brick Cracks: If you notice brick cracks moving in a horizontal direction you may be looking at a symptom of foundation failure. This is usually caused by soil under your home pressing against the foundation. The walls can cave inwards as a result. These cracks can grow until the wall collapses if not treated.

Vertical Brick Cracks: This is yet another common sign of foundation failure. Vertical cracks can indicate that your home may be shifting. The foundation will shift if there are soil changes. This can lead to cracks in bricks, as well as other problems such sagging floors.
