Boral Keystone® systems provide infinite flexibility for design variation and individuality. The range of components and installation methods cater for straight, curved and terraced walls, level or stepped foundations and capping, and a near vertical or set-back face. Then there is a choice of standard or flushface, and a selection of popular standard colours or custom colours can be ordered for larger projects
Keystone® systems are designed to reduce construction time and cater for all locations. The modular blocks can be moved and installed without the need for heavy lifting machinery, and the dry stacked, mortarless installation provides less complex, more rapid construction.
Boral Keystone® combines the durability of concrete units and interlocking fibreglass pins to produce maintenance free walls with life expectancies of 50 to 100 years
