Vineyard and Trellising Solutions

Resilient and Pest Resistant

Safe, Strong and All Australian

Suitable for organic orchards and horticulture. Long lasting support for your vineyard trellis systems. No harsh chemicals or toxins are seeping into the soil. Wet and acid soil conditions do not affect the integrity of the post. they will not rot or burn and never be eaten by insects.

Made in northern NSW by Australians for Australians.

Scroll through the gallery below that feature concrete fence posts being used for Vineyard support posts. Visit our other galleries to see how they are used for other trellis systems like Dragonfruit, Custard Apples and Passionfruit Trellis’s as well.

Vineyard Trellising Solutions 

These are safe and strong structures that can last for centuries without affecting our ecosystem. Prestressed posts limit plant disease and are very resistant to the outdoor environment over a long period of time 

High load capability due to concrete with a low water/cement ratio able to be compliant with even the toughest infrastructure requirements. The concrete posts are used extensively in agriculture for vineyards, fruit production, animal enclosures and to support irrigation systems. 

Higher span between posts 

It is important to note that whereas normal post spacing in vineyards does not exceed 18 feet, the extra strong concrete posts were successfully installed at 30 foot intervals. This further reduced the overall cost of the trellis. 

Finally, vines were affixed to the fruiting wires as per standard practice. 

Based on material cost alone, the concrete post is clearly superior over treated wood posts. Additional advantages of concrete over wood include its strength, durability, simple wire-to-post fastening, ease of wire re-positioning, fewer posts required per trellis row, and concrete material impervious to lightning, fire, rot, and wood-boring insects. 

the use of sustainable concrete posts for trellising and fencing is economically and environmentally beneficial. 

HOLES IN CONCRETE 

Holes are cast into the posts to provide attachment points for transverse supports and to thread with wire or cable if required.

The posts are  made using pre-stressed concrete which is vibrated to eliminate weaknesses. An added effect of vibration is smooth posts with uniform shapes that also facilitate mechanical harvesting. 

Unlike reinforced concrete, which incorporates steel reinforcing bars (rebar) to strengthen concrete for use in various forms of construction such as bridges and high-rises, pre-stressed concrete has additional strength that allows it to support greater spans than ordinary reinforced concrete. What this means in the vineyard are strong end-posts that can support lengthy training wires and fruit-laden vines. Standard reinforced concrete isn’t resilient enough to withstand the same pressures, reducing its endurance and potentially increasing the frequency of replacement. Australian Concrete Posts claims that its pre-stressed concrete posts are resistant to shocks, wind gusts, atmospheric agents and chemical inputs used in the vineyard. They also increase the potential for mechanizing the vineyard operation: Hit a concrete post with a tractor or harvester (we don’t recommend it), and it will likely suffer less damage than a wooden post, which is more likely to need replacement. Ditto for metal posts, which will likely bend if you run into them with equipment (again, not recommended). However, metal posts are typically fabricated to have elevated resistance to wind stress and other factors, depending on the vineyard site. 

Unfortunately, wood posts do not last forever. In humid conditions combined with high temperature fluctuations, wood deteriorates much faster, especially if posts are in-ground. Reports from New Zealand indicate that even sustainable wood posts cannot compete with concrete posts for longevity. 

What are the real alternatives to wood posts? In my vision, in the next 100-150 years, the future of vineyard trellis will be built using prestressed concrete posts using 40mpa concrete with no lime content. These are safe and strong structures that can last for centuries without affecting our ecosystem. 

The obsolescence of these concrete posts would be much less because they can withstand the weight of loaded grapes, strong winds, extreme climate changes, etc. The idea on using concrete posts for the vineyards is not a new one but unfortunately, has not yet found support among growers. Using concrete posts for vineyards is relatively rare, but here are some examples of their use in the USA since 1914 and persistent use for the last 60 years in Moldova and some areas in Hungary. Concrete posts have also been used for decades in New Zealand.
