corroding mild steel balusters cracking masonry to balustrade walls (half-brick thick)

The subject buildings are 1930’s low-rise blocks of apartments in London of conventional brick and filler joists construction with open access decks and private balconies.

Defect

 

Cracking and dislodging of the brickwork and coping stones to the private balconies balustrade wall was reported and noted.

 

Discussion

 

Action Wall Ties investigated the defects and reported that the causation was found to be due to expanding corrosion of the handrails mild steel supporting balusters built into the masonry.

The corrosion of the embedded mild steel results in the formation of ferrous oxide that expands several times the thickness of the metal it has resulted from, thus breaking out the brickwork splitting  bed joints and lifting of the brickwork.
