Treated Pine Sleepers 200 x 50mm x 2400/3000/1800mm - H4 Treated Timber for Landscaping and Retaining Walls

Yes, treated pine sleepers vary in quality. At Australian Treated Pine, we produce only high-quality sleepers that are H4 rated, suitable for external in-ground use.

When used correctly, treated pine sleepers can last up to 20 years.

Like all timber, treated pine is a natural product and can be prone to surface cracking and splitting, especially when fully exposed to the weather. To minimize the effects of weathering, we recommend applying a high-quality oil.

Wet treated pine sleepers are a cost-effective, non-structural product ideal for garden edging, fencing, baseboards, and other outdoor uses. Although they are treated for outdoor use, they have not been kiln-dried or structurally graded.

CCA treated pine is timber that has been pressure treated with a preservative containing copper, chromium, and arsenic (CCA) according to Australian Standards. This treatment protects the timber from termite infestation and decay caused by fungi.

CCA treated pine is safe to use in typical building projects and household environments. It is recommended to follow standard safety precautions, such as wearing a dust mask and protective gloves, but no special measures are necessary. You can saw, drill, plane, and paint treated timber without concern.

Alkaline Copper Quaternary (ACQ) is a water-based wood preservative method that has been recently introduced in countries seeking alternatives to copper, chromium, and arsenic (CCA) treatments.

ACQ treated pine is safe because it does not contain arsenic or chromium. This makes it ideal for use in building raised garden beds, outdoor furniture, and playgrounds.

Sleepers are a popular choice for building retaining walls. To construct a retaining wall with sleepers, ensure that the posts are properly installed in the foundations at the correct intervals. This is essential for the retaining wall to support the weight of the soil behind it. H4 or higher treated pine sleepers are recommended for wet and damp environments to prevent rot and decay.

H4 treated pine is safe for vegetable gardens. Our ACQ treated pine does not contain arsenic, ensuring it won't affect your health. However, it's important to choose materials that you feel comfortable with. There are many other options available at landscapesupply to suit your preferences.

H3 treated pine is suitable for off-the-ground applications, while H4 treated pine is designed for use in contact with the ground and in potentially wet or damp environments. For ground-level installations, it's best to use H4 sleepers to ensure durability and longevity.

The cost of a garden sleeper varies depending on the type of wood, size, treatment type (such as CCA or ACQ), and the supplier. On average, garden sleepers range from $14 to $60, depending on these factors.

When choosing treated pine sleepers for retaining walls, consider the following:

1. Correct Size: Select the appropriate size based on the distance between the supporting posts and the height of the wall. The higher the wall and the further apart the posts, the thicker the sleeper should be.
2. Straightness: Opt for sleepers that are as straight as possible. This will make the construction process easier and result in a better-looking finish.

Termites are less likely to eat treated pine sleepers because they are permeated with a chemical solution that resists decay, infestations, and other deteriorating effects. However, treated pine sleepers are not completely immune to termites, so it's important to seal them with a good quality oil for added protection.
