Understanding Masonry Damage


Common Types of Masonry Damage


To repair masonry effectively, it's important to understand the types of damage that can occur:

  • Cracks: These can range from small hairline fractures to significant splits in the masonry.

  • Spalling: This occurs when the surface of the masonry flakes off, often due to freeze-thaw cycles or moisture infiltration.

  • Efflorescence: White, powdery deposits that form on the surface of masonry due to soluble salts in the material.

  • Discoloration: Staining or weathering that can affect the appearance of the masonry over time.


Causes of Masonry Damage


Identifying the causes of masonry damage can help prevent future issues:

  • Moisture Penetration: Water can seep into masonry and cause deterioration, especially during freeze-thaw cycles.

  • Structural Movement: Settling foundations or shifts in the structure can lead to cracks and other damage.

  • Environmental Factors: Weather conditions, temperature changes, and exposure to pollutants can all contribute to masonry damage.

  • Poor Construction Practices: Inadequate mortar mixes or improper laying techniques can weaken masonry over time.

Step-by-Step Masonry Repair Process


 Cleaning the Damaged Area


Start by cleaning the area around the damaged masonry. Use a wire brush to remove dirt, debris, and any loose material. For cracks, use a chisel to clean out the crack and ensure it's free of loose particles.

 Mixing the Mortar


Prepare the mortar mix according to the manufacturer’s instructions. Mix the dry mortar with water until it reaches a thick, peanut butter-like consistency.

 Repairing Cracks


Small to Medium Cracks



  1. Dampen the Crack: Use a spray bottle to moisten the crack. This prevents the masonry from absorbing too much moisture from the new mortar.

  2. Apply Mortar: Use a pointing trowel to fill the crack with mortar, pressing it firmly to ensure a good bond.

  3. Smooth the Surface: Smooth the surface of the mortar with the trowel, blending it with the surrounding masonry.


Severe Cracks



  1. Clean the Crack: Ensure the crack is clean and free of debris.

  2. Inject Epoxy: Follow the epoxy injection kit instructions to fill the crack. This typically involves inserting nozzles into the crack and injecting the epoxy resin.

  3. Allow to Cure: Let the epoxy cure as per the manufacturer's instructions, ensuring a strong bond.


 Repairing Spalling



  1. Remove Loose Material: Chisel away any loose or damaged brick material.

  2. Dampen the Area: Moisten the area with a spray bottle.

  3. Apply Patching Compound: Apply the patching compound with a trowel, shaping it to match the surrounding brick.

  4. Smooth the Surface: Smooth the patched area and allow it to set.


 Replacing Loose or Missing Bricks



  1. Remove the Old Brick: Carefully chisel out the damaged brick and surrounding mortar.

  2. Clean the Cavity: Clean out the cavity, removing any debris and old mortar.

  3. Dampen the Area: Spray the cavity with water.

  4. Apply New Mortar: Apply a layer of mortar to the bottom and sides of the cavity.

  5. Insert the New Brick: Place the new brick into the cavity, pressing firmly.

  6. Fill Joints with Mortar: Fill the joints around the new brick with mortar, smoothing with a trowel.


 Curing and Sealing


Allow the repaired areas to cure according to the mortar manufacturer’s instructions, typically 24-48 hours. Once cured, apply a masonry sealer to protect the brick from future moisture damage.

Maintenance Tips



  • Regular Inspections: Periodically inspect your masonry for signs of damage and address issues promptly.

  • Keep Bricks Clean: Regularly clean bricks to prevent the buildup of dirt and salts.

  • Apply Sealer: Use a masonry sealer every few years to protect against moisture infiltration.
