Retaining Wall Blocks After Extreme Rain: What Does AS 4678 Mean Here?
Heavy rain can increase soil pressure and expose drainage problems behind retaining walls. Retaining wall blocks must form part of a properly designed system that considers soil conditions, wall height, foundations, reinforcement and drainage. Australian Standard AS 4678 provides guidance for earth-retaining structure design. After extreme rainfall, check for blocked drains, water build-up, new cracks or wall movement. Besser blocks and segmental retaining systems require appropriate site-specific assessment. Contact a trusted retaining wall block supplier or qualified professional to discuss suitable materials and solutions for your project.
