How do you fix crumbling bricks on a house?
Similarly one may ask, why are the bricks on my house crumbling?
Spalling happens when moisture inside thebrickexpands and contracts due to temperature changes. Itcausesbrick to lose its topmost layer. Because of this,stressbuilds up inside the brick because the mortar doesn'tletthe moisture escape to the surface of the brick where itcanevaporate.
In this regard, what causes brick erosion?
Erosion. Brick walls are typicallydurable,but they are not impervious to erosion.Brick andmortar expands and contracts as moisture entersand evaporates. Overtime, the natural expansion and contraction ofthe brick andmortar caused by water infiltrationcauses erosion, orcrumbling of the mortar.
You can arrest and stop the flaking ifyoucan stop water from entering the brick. The bestwayto try to do this is to saturate the brick with aclearmasonry water repellent that contains silanesandsiloxanes.
