Across Melbourne's inner west, the Werribee plains, and the basalt clay country of the northern growth corridors, structural engineers routinely specify 150 Series posts for walls that need to handle the lateral pressures that Melbourne's ground conditions generate. With a 150mm flange width and significantly greater section modulus than the 100 Series, these posts are engineered for walls from 1.5m to 2.0m and beyond. Retaining Walls Direct has supplied 150 Series posts to Victorian engineers, builders, and commercial contractors for over 40 years.\u003c\/p\u003e\u003ch3\u003e150 Series Post Types for Melbourne\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e150 C-Channel (PFC)\u003c\/strong\u003e — heavy duty channel post for walls between 1.2m and 1.8m in stable, well-drained ground.

The Coode Island Silt underlying the inner west, the basalt clay plains of the northern suburbs, and the Silurian mudstone of the inner east all generate significant lateral soil pressure on retaining wall posts during Melbourne's wet winters. The 150 Series provides the structural reserve to handle these loads safely — particularly important given Victoria's strict building permit and engineer certification requirements for walls over 1.0m.\u003c\/p\u003e\u003ch3\u003eVIC Building Permit Requirements\u003c\/h3\u003e\u003cp\u003eAll retaining walls over 1.0m in Victoria require a building permit and structural engineer's certification. 150 Series posts are typically specified in these engineered designs.
