Key Features & Benefits

• ✔
  H4 Hazard Level Treatment: H4 treatment is specifically designed for timber that comes into direct contact with the ground or is exposed to constant moisture. The preservative treatment protects against termites, fungal decay, and rot, significantly extending the lifespan of the timber in outdoor environments. This makes H4 sleepers ideal for retaining walls, garden beds, and fencing.
• ✔
  Pressure-Treated for Strength and Stability: The pressure treatment process infuses the timber with protective chemicals and enhances its dimensional stability. This reduces the risk of warping, splitting, or cracking, even in harsh weather conditions. The result is a strong, reliable sleeper that maintains its shape and integrity over time.
• ✔
  Natural Timber Aesthetic: H4 Treated Pine Sleepers retain the natural grain and texture of pine, offering a warm, organic look that complements a wide range of landscaping styles. They can be left to weather naturally or customised with stains or paints to match your outdoor décor.
• ✔
  Wide Range of Sizes: Available in various dimensions, H4 sleepers can be tailored to suit different project requirements—from small garden borders to large-scale retaining walls. This flexibility makes them a go-to material for landscapers and builders alike.
• ✔
  Standards-Compliant and Sustainable: These sleepers comply with AS/NZS 1604, the Australian and New Zealand standard for preservative-treated timber. Sourced from sustainably managed plantations, they support eco-conscious building practices while delivering high performance.
