Retaining Walls Direct delivers concrete sleepers, galvanised steel H-beam and C-channel posts, drainage products and retaining wall accessories to Griffith, Leeton, Yenda, Hanwood and surrounding areas across the Riverina region of New South Wales. We supply residential homeowners, landscapers, builders and civil contractors throughout the Griffith City LGA.
Griffith sits in the Murrumbidgee Irrigation Area — a flat to gently undulating plain dominated by irrigated agriculture. Soils in the region are predominantly heavy clay (often red-brown earth or grey cracking clay). These highly reactive soils expand dramatically when irrigated or during rainfall and contract and crack in dry periods — creating the shrink-swell cycle that causes the most retaining wall failures in inland NSW. Irrigation in adjacent paddocks can also raise water table levels seasonally, affecting wall drainage.
Important: Retaining wall approval requirements in Griffith vary by wall height, location and soil conditions. Always consult Griffith City Council or engage a licensed engineer before starting any wall. Retaining Walls Direct is a materials supplier only.

Griffith's dominant soil types are red-brown earth and grey cracking clay — both highly reactive. These soils hold moisture for extended periods in the irrigation season and crack to depths of 500mm or more during dry periods. For retaining walls in Griffith, this means: post spacing should not exceed 1.5m; 50MPa sleepers are preferred; drainage must be aggressive and maintained; and geotextile fabric must correctly prevent clay migration into drainage aggregate. Seasonal irrigation from neighbouring paddocks can raise groundwater levels and increase hydrostatic pressure significantly.
In NSW, retaining walls over 1.0m or within 1.0m of a boundary generally require development consent under the Environmental Planning and Assessment Act 1979 and applicable SEPP. Contact Griffith City Council to confirm requirements for your specific property before commencing.
Drainage design is critical in Griffith's irrigation-influenced environment. Every retaining wall must include: 20mm drainage aggregate for the full retained height; slotted ag-drain pipe at the base directed to a legal outlet (not onto neighbouring irrigation areas); heavy-duty geotextile fabric (min 140gsm) between backfill and aggregate to prevent clay migration; and weep holes at 1.8m centres. In areas adjacent to irrigated paddocks, consider extending drainage aggregate depth and increasing weep hole frequency. Browse drainage products →
Walls over 1.0m or within 1.0m of a boundary generally require development consent from Griffith City Council under NSW planning law. Always confirm your specific requirements with council before commencing.
Irrigation from adjacent paddocks can raise the water table beneath and behind retaining walls, increasing hydrostatic pressure significantly. Drainage design must account for this seasonal load, not just rainfall. An engineer should assess walls in irrigation-adjacent locations.
50MPa sleepers are recommended for Griffith's reactive clay conditions. The higher strength and density provide better resistance to the lateral loading from shrink-swell clay movement. Browse 50MPa sleepers →
