Concrete Under Fence Plinths Canberra ACT

Concrete Under Fence Plinths — Canberra & ACT

Canberra's hilly terrain, sloped suburban blocks, and frost-affected soils create persistent gaps under fences that allow soil erosion, pest entry, and an untidy finish. Concrete under fence plinths are the trade-standard solution — a solid, durable precast base that sits beneath your fence panels to seal the gap, retain soil, and deliver a clean, professional result that withstands Canberra's harsh climate. Retaining Walls Direct has supplied plinths to ACT builders, landscapers, and homeowners for over 40 years.

Where Are Plinths Used in Canberra?

Concrete under fence plinths are particularly useful across Canberra's hilly suburbs including:

Sloped blocks in Belconnen, Tuggeranong, Gungahlin, and the inner north where fence lines run across gradients
Filling gaps under existing fences caused by frost heave or soil settlement
Creating a level, solid base for new fence installations on uneven ACT ground
Retaining small amounts of soil (up to 200mm) along a fence line without a full retaining wall
Pool fencing compliance — eliminating gaps that breach ACT pool barrier safety requirements

ACT Planning Requirements

Fence plinths used for minor soil retention along a boundary may be subject to development approval depending on height and location in the ACT. Check with ACT Planning before commencing work. For walls retaining more than 300mm of soil, a full retaining wall system is recommended — see our Concrete Sleepers Canberra range.
