Frost heave, reactive clay soils, and extreme temperature swings across the ACT place exceptional lateral loads on retaining wall posts. Retaining Walls Direct supplies the full range of hot-dip galvanised steel posts to builders, landscapers, and homeowners across Canberra and the ACT, backed by over 40 years of hands-on trade experience.\u003c\/p\u003e\u003ch3\u003ePost Types Available\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eH-Beam (Universal Column) Posts\u003c\/strong\u003e — maximum strength for tall walls, reactive clay, frost-affected ground, and engineer-specified designs.
