Landscape Edging for Retaining Wall Base Borders

Drive stakes into the ground at a 45-degree angle through the stake pockets to lock the edging securely. Sure-loc's dual stake locking system ensures sections connect without overlapping. For retaining wall bases with slope changes or curves, aluminum edging is recommended for its flexibility. Always overlap sections per product instructions and use extra-long stakes in sandy or loose soils.

No. Sure-loc aluminum edging is made from high-strength recycled aluminum alloy that offers excellent corrosion resistance and will never rust — even in marine environments or wet soils common near retaining walls. It is non-toxic, UV-stable, and will not crack, rot, or become brittle over its lifetime, making it ideal for permanent border installations.

Standard 4-inch height edging is sufficient for most retaining wall base borders. For steep elevations, deep mulch beds, large rock areas, or sandy soils, Sure-loc's 8-inch SureEdge models provide greater ground penetration and stability. Extra-long 12" or 18" stakes are also available for added hold in challenging soil conditions.

Yes. Landscape edging installed at the retaining wall base creates a physical barrier that contains mulch, gravel, or aggregate. Sure-loc's aluminum and steel edging maintain their position long-term thanks to the dual stake locking system and substantial construction. The 8-inch tall SureEdge model is especially effective for deep mulch or large rock bed applications.

Both are suitable for commercial applications. Steel edging — particularly Sure-loc's 3/16" or 1/4" models with shot blast surface preparation and powder coating — offers maximum durability in high-traffic areas and resists maintenance equipment damage. Aluminum SureEdge is lighter, corrosion-proof, and preferred for institutional or marine-adjacent projects where rust-free performance is critical.

Yes. Sure-loc's Anti-Frost Heave Technology uses 45-degree angled stake pockets that anchor the edging against ground movement caused by freeze-thaw cycles. This is especially valuable at retaining wall bases where soil pressure and frost shifting are more pronounced. The Elite-Edge plastic profile also includes a V-lip specifically engineered to prevent frost heave displacement.
