When to Choose 60MPa Sleepers

60MPa sleepers are the right call when:

• Your wall is over 1.2m in height
• The site has reactive clay, expansive soils, or poor drainage (common across Adelaide's inner suburbs and hills)
• There is significant surcharge load — vehicles, structures, or sloped ground above the wall
• You need a wall engineered to last 50+ years with minimal maintenance
• Your engineer or council has specified a minimum concrete strength

SA Council & Engineering Requirements

In South Australia, retaining walls over 1.0m typically require a building consent and structural engineer's certification. Walls near boundaries may require additional approvals. Key references:

• SA Government — Building Rules & Standards
