Key Aspects of H5 Retaining Walls: Suitability: Ideal for structural, high-moisture, and in-ground applications. Material Options: Common sizes include 200x50mm or 200x75mm treated pine sleepers, and 100x100mm or 150x150mm posts. Lifespan: With proper construction, H5 treated timber can last 25 to 50+ years. Installation Tips: Posts: Use 125x125mm H5 posts at 900mm to 1.2m centres for better stability. Drainage: Crucial to prevent hydrostatic pressure; use drainage gravel and a slotted pipe behind the wall. Fixings: Use hot-dipped galvanized steel nails or screws. Height: Generally, walls over 1m require council approval and engineering certification.
