TUFFPOLY Composite Sleepers are an advanced lightweight retaining solution that deliver the natural look of timber with the lasting performance of cutting-edge composite materials. Each sleeper (available in Drift or Charcoal) weighs under 10kg – almost 10× lighter than concrete – allowing walls to be built easily by hand without the need for heavy machinery or extra labour.

Made from a fibre-reinforced polymer (with no timber or steel), TUFFPOLY Sleepers will never rot or rust and are engineered for a 60+ year design life and come with a 25 year warranty. Designed and tested in Australia, TUFFPOLY Sleepers exceed Australian Standards (AS 4678:2002) and are strong enough to retain earth up to 1.4 metres high.

Now you can achieve the classic beauty of timber, with the strength of concrete and steel, without the weight, complexity, or maintenance issues — saving you time, money, and your back.
