case study 56e19a8f41e004.53961310 1 - Balustrade wall defects

The subject building is part of an estate of 1930s style low-rise blocks of apartments in West London of conventional brick and filler joists built construction with open access decks and private balconies.

Problems with cracks in the Balustrade walls

This very large building is curved with convex walkway balustrade walls.

Outward stepping at the base of the walls, together with outward leaning and cracking of the brickwork and coping stones to the walkways’ balustrade walls, was reported and noted.


Action Wall Ties investigated the defects and reported that the causation was found to be due to seasonal moisture, thermal expansion and contraction i.e. hygrothermal movement.

The expansion had pushed the walls outwards, in some cases stepping out the base of the wall and the wall leaned outwards.
