Furthermore, the arrised (chamfered) edge profile prevents sharp corners and gives a clean, professional appearance for visible landscaping applications.

Why Choose H4 CCA Treated Timber Sleepers?

First and foremost, H4 CCA treatment provides the highest level of protection for timber in direct ground contact, far exceeding H2 and H3 rated products that are only suitable for above-ground use. Furthermore, the CCA (Copper Chrome Arsenate) preservative penetrates deep into the wood for protection that lasts decades. As a result, H4 timber sleepers outlast untreated timber many times over in retaining wall applications. In addition, the treated pine base material is consistent in size and straight, making for easier installation. According to the Australian Department of Agriculture, treated timber products must meet specified standards for use in agricultural and landscaping applications.

Installation Tips for Treated Pine Sleepers

Before installing your retaining wall, plan the layout and calculate the correct number of sleepers for each course. Then, set the first course on a compacted gravel base to ensure stability and drainage. In addition, use galvanised or stainless steel fixings to prevent corrosion staining on the treated timber. Finally, backfill progressively and compact well to ensure the completed retaining wall maintains structural integrity over time.
