The proven Concrib sleeper wall system was specified for Mirvac’s latest development in New South Wales with the intention to present the blocks near flat and ready for building.

Mirvac’s latest planned community at Saddlers Ridge in Gilleston Heights near Maitland, NSW is a premium development, and offers the exclusive lifestyle of a country atmosphere and spectacular rural outlook, with all the amenities of a town. Client requirements necessitated a retaining wall system that would tick all the boxes for maximising land value, be aesthetically pleasing and meet the design life standards for residential retaining wall systems.

Concrib has designed and installed a wide range of earth stabilisation systems for civil and building contractors, government authorities, architects and consulting engineers. 

Concrib was engaged by the contractor Robson Civil to supply and install a vertical cantilever concrete sleeper wall system. Concrib installed 600 square metres of walling reaching up to a height of two metres.

Concrib’s concrete sleeper wall system was suited to the development for a number of reasons. The system’s narrow construction footprint used minimal space and kept the value of the land as high as possible. The concrete sleeper wall’s design and subtle wood grain finish allowed seamless blending with the land, contributing to the rural feel. Additionally, the retaining wall meets AS4678, the Australian Standard for Earth Retaining Structures, which requires residential retaining walls to have a design life of at least 60 years.

Fencing requirements were simplified with Concrib’s standard ‘fence connection’. Galvanised posts with lengths of steel extending at the tops meant the fence posts above the wall could be easily attached.

Concrib’s engineered retaining wall combines the aesthetics of a wood grain finish with the strength, durability and longevity of concrete. Unlike a wooden wall, these sleeper walls are termite-free and will never rot.

Once installed, Concrib’s sleeper retaining walls can be painted in a wide variety of colours. Concrib uses a highly resistant specialist concrete sealant to ensure the sleeper walls remain aesthetically pleasing for years to come.
