Our sleepers are specified by many companies. We often assist with difficult or non standard designs for site specific retaining walls. We encounter poor soil conditions, existing infrastructure issues as well as high surcharge requirements. We work with our Engineers or our clients engineers to come up with a practical solution. We supply our sleepers to Qld Rail for some of their network maintenance and enhancement projects. Their Engineers design retaining walls using our “off the shelf” sleeper specification saving them time and money. It is also a requirement that the retaining walls have a long service life. This is a new piece of upgraded infrastructure at Murarrie requiring a specific practical retaining wall. The steel posts on this wall are heavy duty and were ordered in specific sizing for this job. Qld Rail crews carried out the construction and have done a nice job.
