Advantages Over Concrete Sleepers:
The key advantages of SuperSleeper™ over traditional concrete sleepers are numerous:

1. Lightweight Nature: SuperSleeper™ weighs less than 6 kilos, making it significantly lighter than typical concrete sleepers, which are around 75 kilos. This weight reduction translates into substantial financial savings, including reduced labour, machinery, and logistics costs.
2. Durability: SuperSleeper™ is engineered to last and meets a 60-year design life requirement for retaining walls. It is highly durable and can withstand the test of time.
3. Ease of Installation: The lightweight nature of SuperSleeper™ makes installation faster and easier. It eliminates the need for heavy machinery and two-man lifts, resulting in approximately 30 to 40% faster installation compared to traditional methods.
4. Flexibility: SuperSleeper™ can be cut easily using common tools like a circular saw or grinder, allowing for precise customization to fit various project requirements.
