Plastic Wedges 15mm are a practical installation accessory for concrete sleeper retaining wall systems. They are used to help pack, align, and secure concrete sleepers inside steel retaining wall posts during installation, making it easier to achieve a neat, stable, and consistent wall finish.
Supplied in a pack of 100, these wedges are useful for installers, landscapers, builders, and DIY retaining wall projects where small adjustments are needed between the sleeper and post. They help reduce movement, improve fit-up, and support cleaner alignment during concrete sleeper wall construction.
Plastic wedges are used during concrete sleeper retaining wall installation to fine-tune the fit between sleepers and steel posts. Because site conditions, post alignment, sleeper tolerance, and wall layout can vary slightly, wedges provide a simple way to pack out small gaps and help hold the sleeper position more securely.
They are especially useful when installing sleepers into galvanised C posts, H posts, and corner posts where the installer needs to maintain a consistent face line. Correct packing can help reduce unwanted movement, improve the finished appearance of the wall, and make installation more controlled.
Plastic wedges should be used as an installation aid, not as a substitute for correct post spacing, footing depth, post alignment, or sleeper selection. Posts should be set accurately, sleepers should match the post spacing, and the wall should be installed according to the required design and site conditions.
Use wedges only where small packing adjustments are needed. Large gaps, leaning posts, incorrect post centres, or poor footing alignment should be corrected properly before the wall is completed.
Plastic Wedges 15mm are available in a pack of 100, with bulk box quantities available by request. Delivery is available across Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Gold Coast, and regional Australia. Get a free quote for your retaining wall accessories.
