Concrete Under Fence Plinths Adelaide

Concrete under fence plinths from Lonsdale keep Adelaide fence lines straight and dry. Each 50mm plinth retains the soil step under a fence and ends timber-to-ground contact, in colours matched to the SA-made sleeper ranges.

Concrete under fence plinth for added privacy and durability – ideal for fencing and retaining wall support

The Adelaide case for concrete plinths

Adelaide’s hills-face and foothills suburbs put a soil step under a huge share of boundary fences. Left alone, that soil migrates under the fence, holds moisture against the palings, and shortens the life of the whole fence line. A 50mm concrete under fence plinth is a permanent answer: concrete retains the soil, concrete takes the ground moisture, and the fence above it stays clear of the dirt for its full service life.

Colour-matching to the SA ranges

RWS plinth ranges match local sleeper colours, and Adelaide is supplied with the SA-made sleeper ranges, including the 60MPa SA line. That means a plinth run can continue the finish of an adjacent sleeper wall along the same boundary, rather than introducing a mismatched grey strip. Where the level change exceeds what a plinth should hold, step up to full concrete sleepers, steel-reinforced with N10 or N12 reo, AS3600 compliant and engineer-certified with a 50-year lifespan on certified ranges, on galvanised posts from the Adelaide steel range. Structural walls need engineering sign-off, which RWS does not provide; see retaining wall engineering for what certification involves.

Ordering from Lonsdale 5160

All Adelaide stock, plinths, sleepers and steel, runs through the Lonsdale 5160 warehouse, so combined orders leave together. Delivery is by external transport with forklift access required at the address. Trade customers get next-day pickup or 72-hour delivery on paid orders through the trade portal, and the instant quote calculator prices wall components in minutes.

Do plinths work under Good Neighbour style steel fences?

Yes. The plinth sits beneath the fence line and retains soil independently of the fence material. Steel fences gain a solid soil barrier at the base; timber fences gain that plus protection from rot-inducing ground contact.

Who pays for plinths on a shared Adelaide boundary?

Cost sharing on boundary fencing is a matter between neighbours under SA’s fencing arrangements, not something RWS determines. What we can do is quote the materials precisely so both parties agree on numbers before work starts; send fence length and soil-step details via contact us.
