50MPa concrete sleepers are the heavy duty specification for retaining walls on reactive clay soils, walls over 1.0m in height, and sites with elevated surcharge loads such as driveways, vehicles, or structures. The higher compressive strength provides greater resistance to bending and cracking under demanding conditions.
For the most demanding applications, see our Premium 60MPa Concrete Sleepers. For standard residential walls, see 40MPa Concrete Sleepers. Not sure which spec you need? Read our Concrete Sleeper Specification Guide.
