Twinbloc
A UNIQUE STACK-BONDED APPEARANCE WITH STRUCTURAL INTEGRITY
Twinbloc masonry is the fast, sure, economical way to create the impressive appeal of 'stack bonding'. Created to standard block proportions, Twinbloc incorporates a carefully gauged central groove to give the appearance of two half blocks when laid and yet, as it is laid stretcher-bond, it provides the inherent strength of any Specification Masonry wall removing the need for bed-joint reinforcement to stabilise the wall in the majority of situations. It is available in a choice of:
