Landmark™ is a positive mechanical connection retaining wall system that achieves high performance under extreme loading conditions. It is designed with a unique locking connection between block facing and grid that offers unparalleled connection strength with a range of geosynthetic reinforcement products. A lock bar made from an engineered polymer fits into a specially designed channel built into the blocks. This locking system mechanically and positively connects the block to a layer of reinforcing material. Specially shaped flanges establish a uniform course-to-course set back and ensure a strong resistance to shear forces. Landmark™ is designed specifically for tall walls over 4.5 metres, high load bearing walls, infrastructure, industrial and transportation applications and structures located in seismic regions. Landmark™ is available only on a made to order basis.
