Choosing the right deck material can transform your outdoor space. A deck should feel like a natural extension of your home. It’s a spot to unwind, entertain, and enjoy the fresh air. But choosing the right material for your deck is important, especially in areas where salty breezes and humid summers like the Mornington Peninsula put outdoor surfaces to the test. A deck needs to be more than just good-looking–it also has to stand up to the elements while keeping maintenance manageable. In this blog post, we’ll explore the top two popular options, concrete and timber, to help you weigh the benefits, drawbacks, and best fit for your outdoor space.
Concrete Decking
Concrete decking is a popular choice for those who want a sleek, modern look with long-lasting durability. It’s a versatile material that can be stamped, stained, or textured, with options like exposed aggregate concrete adding unique texture and visual interest.
Advantages of Concrete Decking
- Durability. Concrete is known for its resistance to harsh weather with Strong UV rays and wet damp winters and salty sea breezes and it’s also immune to rotting and pests like termites.
- Low Maintenance. Compared to timber, concrete is relatively low-effort. It’s easy to clean and doesn’t need constant upkeep.
- Versatile Design Options. Concrete can be stamped or stained in different patterns so you can get a range of looks without compromising on durability. For those wondering about its lasting appeal, decorative concrete options continue to offer timeless versatility.
Drawbacks of Concrete Decking
- Heat Retention. If your deck gets a lot of direct sunlight, concrete can heat up fast, making it uncomfortable to walk barefoot.
- Limited Customisation After Installation. Once concrete has been poured and set, any major changes can be costly.
- Difficulty in Repairs. If there are major cracks in the concrete it can significantly diminish the concrete’s aesthetic appeal. Such repairs are difficult and costly to rectify.
Timber Decking
If you love a natural, earthy look, timber decking is a classic choice. Popular timber types for coastal areas include Merbau and Spotted Gum, both offering that beautiful, warm look that complements the surroundings.

Advantages of Timber Decking
- Natural Aesthetic. Timber’s rustic charm gives your space a warm, inviting feel that blends beautifully with nature.
- Cooler Underfoot. Unlike concrete, timber doesn’t retain as much heat which can be a welcome relief in summer.
- Ease of Customisation. Timber can be sanded, stained, and painted over time, allowing you to refresh your deck’s look as you like. Additionally, alterations are fairly simple and straightforward.
Drawbacks of Timber Decking
- Maintenance Requirements. To keep timber looking good, it needs regular sealing or staining to protect against moisture and pests.
- Susceptibility to Weathering. Timber can warp, rot, or splinter over time, especially in the face of coastal elements.
- Higher Cost. High-quality timber can be pricey initially and regular maintenance costs can add up over time.
Key Factors to Consider
Climate and Environmental Conditions
The coastal climate is as stunning as it is challenging for outdoor materials. With exposure to salty sea air, drastically fluctuating temperatures, and a fair amount of rainfall, both concrete and timber decking will experience environmental stressors. Concrete is a popular choice for long-term durability because of its natural resilience against moisture and pests. Salt air doesn’t easily impact concrete so it’s less likely to show wear from exposure.
On the other hand, timber is more vulnerable to coastal effects. Prolonged exposure to humidity and rain can cause timber to absorb moisture, leading to warping, rotting, or splintering over time. However, it doesn’t mean it can’t work on the peninsula, but it will require regular maintenance to keep it in top shape. Opt for durable wood like Merbau or Spotted Gum as these work well in coastal conditions.
Lifestyle and Maintenance Preferences
One of the biggest factors when choosing between concrete and timber decking is how much maintenance you’re willing to take on. Concrete is ideal for homeowners looking for a low-maintenance option as it only requires a regular sweep or occasional hose-down to keep clean. With concrete, you won’t have to worry about constant resealing or staining, which is a time-saving choice for those with busy schedules or simply less interested in upkeep.
Timber is for those who enjoy outdoor care and value a natural, evolving look. Timber decking needs periodic sanding, staining, or sealing to protect it from moisture and pest damage. This doesn’t just preserve its appearance, but it will also extend its lifespan.
Budget Considerations
Concrete comes with a lower initial installation cost plus its minimal maintenance makes it a cost-effective short and long-term choice. Since concrete is durable and unlikely to need replacement or regular upkeep, it’s a good option for those prioritising budget stability over time.
Timber has a wider price range depending on the type of wood. Merbau and other hardwoods come at a premium but they bring a natural elegance to the deck that’s hard to beat. Beyond the initial cost, you also have to budget for ongoing maintenance expenses including periodic treatments and repairs. Homeowners should weigh whether the aesthetic and other benefits warrant the higher upfront cost and incremental maintenance with timber.
Sustainability
For eco-conscious homeowners, sustainability can play a key role in material selection. Concrete has evolved to include greener options like Holcim’s ECOPact concrete, which reduces carbon emissions without sacrificing strength and durability, making it an excellent choice for long-lasting, environmentally-friendly decks.
Timber also offers sustainable choices, particularly when sourced responsibly. Many Australian hardwoods, like Merbau and Spotted Gum, are available from suppliers certified by the Forest Stewardship Council (FSC) or the Programme for the Endorsement of Forest Certification (PEFC). Choosing certified timber ensures that the wood is sustainably harvested, supporting responsible forestry practices.
Making the Rice Choice for Your Deck
Choosing between concrete and timber decking ultimately comes down to what matters most to you. Concrete is a smart pick for homeowners prioritising durability, low maintenance, and modern design. On the other hand, timber is perfect for those who love a natural, warm aesthetic, cooler surfaces underfoot, and the ability to refresh or customise the look over time. Each material brings in something unique so think about your budget, style preferences, and how much maintenance you’re ready to take on. Whether you want a deck that’s hassle-free or one with a rustic, natural charm, selecting the right material ensures your deck is a lasting, beautiful part of your home.
