Why the Concrete vs Timber Question Comes Up
Concrete picnic tables have been a fixture in Australian public parks since the 1970s. They're heavy, vandal-resistant and -- in theory -- permanent. But councils and parks managers increasingly find that the 30-year-old concrete tables on their sites are cracking, spalling and uncomfortable to use, while newer hardwood specifications are delivering better outcomes at comparable lifecycle cost.
This guide compares concrete and Australian hardwood timber picnic tables across the metrics that matter most for public outdoor furniture procurement.
Side-by-Side Comparison
| Factor | Concrete Table | Australian Hardwood (Class 1) |
|---|---|---|
| Weight | 300--600kg typical | 100--180kg (Ironbark at high end) |
| Installation | Crane or forklift required | 4-person carry or standard forklift |
| Seating comfort | Hard, cold in winter, scorching in summer | Naturally insulating, comfortable year-round |
| Vandal resistance | High (scratch, graffiti -- but it shows) | High with hardened steel hardware + Ironbark density |
| Maintenance | Spalling repair, rebar rust, grout cracks | Periodic oil (optional), hardware inspection |
| Expected life | 30--50 years (with repair) | 25--40+ years AS 5604 Class 1 (no repair needed) |
| End of life | Concrete waste, difficult to dispose | Biodegradable, can be chipped/composted |
| Accessibility (AS 1428.1) | Fixed bench -- not inherently accessible | Same, but accessible variants available from Auscraft |
| Thermal comfort in AU climate | Poor -- absorbs and holds heat | Good -- timber insulates, doesn't retain heat |
Where Concrete Still Makes Sense
Concrete tables aren't always the wrong answer:
- Extremely high-vandalism sites: Where tables are physically attacked (cut, broken, set on fire) -- concrete's mass provides passive resistance that even Ironbark can't match.
- Coastal saltwater exposure at the waterline: Where standing water and daily wave wash create a permanently saturated environment. Concrete is inert to salt; even Class 1 timber needs some height above tidal reach.
- Budget-constrained permanent installations: In some markets, pre-cast concrete tables can be sourced for less than custom hardwood.
Where Australian Hardwood Wins
For the majority of Australian park, school and commercial outdoor furniture installations, Australian hardwood outperforms concrete on user experience and total lifecycle cost:
- Comfort: A concrete bench seat on a 35 degrees C Australian summer day is effectively unusable. A Spotted Gum bench seat remains comfortable at the same ambient temperature -- a significant factor for school lunch areas and public parks.
- Installation: A 150kg hardwood table moves with a forklift and installs the same day. A 450kg concrete table requires crane mobilisation and may need concrete footings to distribute the load without cracking paving.
- AS 5604 compliance: Australian Class 1 hardwood species provide a measurable, third-party validated durability standard that can be referenced in council tender specifications. Concrete doesn't carry an equivalent durability class under the same framework.
- Accessibility: Auscraft can build open-ended accessible variants in any hardwood species, meeting AS 1428.1 without a separate purchase.

Cost Comparison Over 30 Years
Initial purchase price is rarely the relevant metric for public outdoor furniture. The 30-year lifecycle cost matters more -- particularly for councils with long-term asset replacement schedules.
- Concrete: High initial cost (crane, footings, install), potential repair cycle (spalling, rebar rust) at 15--20 years, difficult to dispose at end of life.
- Hardwood Class 1: Moderate initial cost, no repair cycle expected for 25+ years, biodegradable end-of-life disposal.
For councils that track assets on 20--25 year depreciation schedules, AS 5604 Class 1 hardwood is typically compliant with the expected asset life -- whereas a concrete table that begins spalling at year 15 represents an unplanned maintenance event.
Frequently Asked Questions -- Concrete vs Timber Picnic Tables
Are concrete picnic tables better than wooden ones for Australian parks?
For most Australian parks, AS 5604 Class 1 hardwood (Spotted Gum, Ironbark) offers better comfort, comparable durability and easier installation than concrete. Concrete has advantages only at extreme vandalism or tidal splash sites. In standard parks, the thermal discomfort of concrete in Australian summer makes hardwood the preferred specification.
How long do hardwood picnic tables last compared to concrete?
Class 1 hardwood lasts 25--40+ years with no repair cycle. Concrete lasts 30--50 years but typically requires spalling and rebar treatment at 15--20 years. The expected lifespans are similar -- but the hardwood requires no maintenance intervention during its service life.
What does a council need to specify for hardwood instead of concrete?
Specify AS 5604 Durability Class 1, UNSPSC 56101700, and AS 1428.1 accessible variant if required. Auscraft can supply a formal quotation and specification sheet in council tender format -- contact us with your site brief.
