Many physical signs are observed when stone and brick constructions require repair. The restoration of the brick or stone structure might only require the lintel restoration in Sydney for few masonry pieces that were damaged by accidental blunt force collisions.
It needs to grind out the mortar around the damaged units, then remove the damaged units, and then re-pointing to their original position using an appropriate mortar.
There are also times when more significant restoration efforts are required if parts of a masonry structure start to discolor and spalling the bricks (cracking as well as chipping) cracks in mortar and crumbling.
These are indications that the structure of the masonry is being attacked by elements on the inside and the material that makes up the wall starts to fall apart. This kind of damage is typically caused by water infiltrating the stone or brick structure and getting trapped in the.
When thawing and freezing occur, the stone can expand and contract at various rates, which causes a break throughout the entire material including mortar and bricks. This kind of degrading has to be stopped by locating the cause of the leakage of water, be it leaky wall flashing, or wall cap.
When the leak is discovered and stopped, there are several options for repair or replacement based on the severity of the damage. If the severity of the damage is substantial enough, it is possible that it is better (cost and time-wise) to replace the entire structure or wall.
