Under-fence plinths are pre-stressed reinforced concrete strips (50mm thick) that close the gap beneath a fence — keeping pets and soil in, weeds and erosion out. In Plain, Timberlook and Composite to suit any fence style. Australian-made, delivered Australia-wide by Retaining Walls Direct.
Written and product-checked by the Retaining Walls Direct team — supplying concrete retaining wall and fencing products across Australia. Last updated: June 2026.
An under-fence plinth seals the gap at the base of a fence (or tops a low retaining wall). Pre-stressed reinforcement reduces cracking and adds strength, and the range suits Colorbond steel, timber paling and composite fences — ideal on reactive clay where ground movement opens gaps under the fence line.
