Spalled Brick Masonry on Retaining Wall
Multiple bricks in the retaining wall are spalling (face surface breaking away), likely due to freeze-thaw cycles and moisture infiltration over time. The damage appears concentrated in the lower courses where moisture exposure is highest. If left unaddressed, the structural integrity of the retaining wall will continue to deteriorate as more bricks fail.
DIY Feasibility
Requires matching old brick and mortar color plus proper repointing technique to avoid further damage.

Check for visible signs consistent with the diagnosis before proceeding.
What to do right now
- 1Clear soil and debris away from the damaged area to improve drainage
- 2Apply temporary clear masonry sealer to intact brick surfaces to slow further moisture penetration
- 3Install or improve gutters/downspouts to redirect water away from the wall
These are interim steps to slow or contain the issue while you arrange a proper repair.
