Our team was inspired to create NOTWOOD when they recognized the demand for easily available retaining walls in Australia without the use of costly laborers and equipment. With more than 20 years of experience in the concrete sleeper business, we are well-versed in the characteristics of high-quality sleepers that are easy to install and that let you build your own retaining walls for a much lower price. The NOTWOOD product line is renowned for its quality, variety, and affordability and is supported by our parent business, Outback Sleepers Australia, which has been producing concrete products for more than 20 years.
