What is Spalling Brick?

Updated: Aug 26

Brick has been a popular building material for centuries, prized for its durability, aesthetic appeal, and low maintenance requirements. However, even brick can become damaged over time, and one of the most common forms of brick deterioration is known as spalling.


Understanding Spalling Brick


Spalling brick refers to the process where the face of a brick chips, flakes, or peels off. This damage typically occurs on the surface of the brick that's exposed to the elements. Spalling can range from minor surface flaking to large chunks of brick falling away, compromising the structural integrity of the wall or building.


Signs of Spalling Brick

To identify spalling brick, look for these signs:


1. Flaking or peeling of the brick surface

2. Cracks or pits in the brick face

3. Crumbling mortar between bricks

4. Pieces of brick on the ground near the wall

5. Discoloration or efflorescence (white, powdery deposits) on the brick surface


Many homeowners and property managers have no idea they have a spalling brick issue until they go to clean the brick and notice the signs.


What Causes Brick Spalling?


Several factors can contribute to brick spalling. Understanding these causes is crucial for prevention and proper repair.


Moisture Infiltration


The most common cause of spalling is moisture infiltration. When water enters the brick through tiny pores or cracks, it can freeze and expand in cold weather, causing the brick face to pop off.


Poor Quality Bricks

Bricks that are improperly manufactured or of low quality are more susceptible to spalling. These bricks may have a higher water absorption rate, making them more vulnerable to freeze-thaw cycles.


Age and Weathering


Over time, exposure to the elements can wear down even the highest quality bricks. UV rays, acid rain, and temperature fluctuations can all contribute to brick degradation.


Improper Cleaning Methods


The way you clean brick is important. Using harsh chemicals or high-pressure washing can damage the protective outer layer of bricks, making them more susceptible to spalling.


Salt Crystallization


In coastal areas or regions where de-icing salts are used, salt can penetrate the brick. As the salt crystallizes, it expands, causing the brick surface to flake off.


How to Fix Spalling Brick


Addressing spalling brick promptly is crucial to prevent further damage. The repair method will depend on the extent of the damage.


Minor Spalling Repair


For minor surface spalling:


1. Clean the affected area thoroughly

2. Apply a breathable masonry sealer to prevent further moisture infiltration

3. Use a color-matched mortar to fill in small chips or cracks


Extensive Spalling Repair

For more severe spalling, you should hire an expert. They will perform the following:


1. Remove damaged bricks carefully

2. Clean the surrounding area and prepare it for new bricks

3. Install matching replacement bricks

4. Repoint the mortar joints

5. Apply a waterproof sealant to protect against future moisture damage


Preventive Measures


To prevent future spalling:


1. Ensure proper drainage around the building

2. Regularly inspect and maintain gutters and downspouts

3. Apply breathable sealants to protect against moisture infiltration

4. Address any signs of water damage promptly
