Under Fence Plinths

Under Fence Plinths

Under Fence Plinths are a practical and durable solution for closing the gap beneath fencing while improving the finished appearance of the fence line. Designed to suit a wide range of fencing styles, these plinths help reduce gaps at the base of the fence, improve privacy, assist with soil retention, and create a cleaner, more professional boundary finish.

Our concrete under fence plinths are manufactured with pre-stressed reinforcement to help reduce cracking and improve long-term strength. Available in Plain, Timberlook, and Composite options, they are suitable for residential fencing, boundary fencing, Colorbond fencing, timber fencing, and general landscape applications where a durable under-fence barrier is required.

Technical Overview

Under fence plinths are installed at the base of fencing to help close open gaps between the fence and the ground. This is especially useful on sloping blocks, uneven sites, newly landscaped areas, and boundaries where ground levels vary. By reducing the gap below the fence, plinths help improve privacy, reduce the chance of soil washout, and create a more finished appearance along the full fence line.

The pre-stressed reinforced design helps improve strength and reduce the risk of cracking during handling, transport, and installation. Compared with timber or improvised infill materials, concrete plinths provide a longer-lasting and more consistent under-fence solution, especially in outdoor environments exposed to moisture, soil contact, and weather.

Why Use Under Fence Plinths?

  • Closes fence gaps: Helps reduce open space at the bottom of the fence.
  • Improves privacy: Creates a cleaner and more enclosed boundary line.
  • Helps retain soil and mulch: Useful where garden beds, gravel, or landscaping sit against the fence line.
  • Stronger than timber infill: Concrete provides a more durable and longer-lasting solution.
  • Pre-stressed reinforced: Designed to reduce cracking and improve strength.
  • Low maintenance: No painting, staining, or regular treatment required.
  • Weather resistant: Built for long-term outdoor exposure.
  • Termite resistant: Unlike timber, concrete is not affected by termites or other insects.

Choosing the Right Option

Plain Under Fence Plinths are ideal where a simple, neutral, and practical finish is required. They suit modern Colorbond fences, side boundaries, and general residential fencing where appearance is important but a decorative texture is not essential.

Timberlook Under Fence Plinths are a good option when the fence line needs a softer or more decorative finish. The timber-style appearance works well with natural landscaping, timber fencing, garden edging, and homes where a plain concrete face may look too industrial.

Composite Under Fence Plinths are suited to projects where a clean, durable, and practical plinth is required in a format designed for compatible fencing layouts. They are a good choice for modern fencing installations where neat presentation and long-term durability matter.

Design Applications

  • Colorbond fencing
  • Boundary fences
  • Timber fencing
  • Residential side fences
  • Garden and landscape fencing
  • Fence lines on sloping or uneven sites
  • Projects requiring a cleaner under-fence finish
  • Areas where soil, gravel, or mulch needs to be held back beneath a fence

Installation Considerations

Under fence plinths should be installed to suit the fence system, post spacing, and ground conditions. Before installation, confirm the plinth size is compatible with the fence span and post arrangement. Proper site preparation helps ensure the plinth sits level, supported, and aligned neatly beneath the fence.

These plinths are commonly used where a fence alone would leave an uneven or unattractive gap at ground level. They are especially useful on sites with minor level changes, garden edging near the boundary, or where a more finished and enclosed fence line is needed.

If the fence is installed above a retaining wall or in an area with surcharge loads, drainage issues, or structural retaining requirements, the full wall and fence system should be checked to ensure the correct post, footing, and fence fixing method are used.
