Quetta Bond

Quetta Bond is a technique developed after the Quetta earthquake, used in brick and other masonry buildings, where vertical reinforcement is used to improve horizontal and vertical bond between walls (see image)[1]. "The Quetta Bond is simply a slight variant of [the brick laying technique] 1½ Flemish Bond where the voids are filled with concrete and steel reinforcement bars rather than brick. It was almost certainly invented (if that is the right word) by Royal Engineers. The RE was heavily involved in the aftermath of the Quetta earthquake".[2]
