Wooden decking is one of the most traditional solutions for outdoor flooring. Its natural beauty and organic feel make it a popular choice for gardens, swimming pools, terracesand balconies— but not all types of wood offer the same performance, and all require regular upkeep to maintain their appearance and durability.
In this guide, we cover the main types of wooden decking for outdoor use, their real advantages and disadvantages, and how composite decking compares as an alternative. If you’re weighing up natural wood against composite decking, you’ll find the information you need to decide with confidence.
What Is wooden decking?
Wooden decking is a raised flooring surface made up of timber boards fixed to a support structure (joists), also typically made of wood. The term “deck” originates from the upper floor of a ship — traditionally built with parallel planks over a framework that allowed water to drain away, preventing pooling and reducing the risk of slipping.
Today, wooden decking is widely used in residential and commercial outdoor spaces — gardens, pool surrounds, terraces, balconies, patios and outdoor seating areas. The type of wood chosen directly influences durability, maintenance frequency, safety, comfort and, naturally, price.
What are the advantages and disadvantages of wooden decking?
Choosing wooden decking for outdoor use involves considering several factors, such as durability and resistance, maintenance, aesthetics, comfort and safety, installation, price, among others.
Natural beauty
Wooden decking offers unparalleled natural beauty. Each board features unique organic patterns created by nature, adding charm and elegance to any outdoor space.
Safety
Wood is a naturally slip-resistant surface, and the raised deck structure allows water to drain beneath, eliminating the risk of large puddles forming.
Thermal comfort
Compared to other materials, wood has the advantage of heating up less when exposed to direct sunlight, making it more comfortable to walk on barefoot.
Maintenance
To last and maintain its appearance and weather resistance, wooden decking requires annual or biannual maintenance, which may include sanding, painting, varnishing or sealing — representing ongoing costs and effort over time.
Durability and resistance
It can develop cracks, warping, rot and insect damage, including termites, if not properly maintained.
Aesthetics
its appearance can change over time due to ageing, prolonged sun exposure (which can cause colour loss) and general wear.
Safety
Some woods develop knots and tend to produce cracks or splinters over time, which can pose a safety risk, particularly for children and pets.
Cost
High-quality wooden decking, such as ipeand teak, tends to be expensive. Treated pine is more affordable, but can still prove costly in the long run when ongoing maintenance costs are factored in.
Access to the substructure
Traditional fixing systems make it difficult or impossible to access the area beneath the deck, which means it is very hard to treat the support structure or clean debris that may accumulate.
Installation
The fixing systems commonly used for wooden decking are slower to install compared to other alternatives.
The Alternative: CDECK® Composite Decking
If you appreciate the look of natural wood but want a solution with greater durability and no need for ongoing maintenance, CDECK® composite decking addresses each disadvantage of timber:
No ongoing maintenance
CDECK® does not need to be sanded, varnished, oiled or painted. Maintenance consists of periodic washing with water and a neutral detergent. No annual treatment costs.
No splinters or cracks
The surface is smooth and stable — it does not develop splinters, does not crack and does not split. Comfortable to the touch and safe for walking barefoot, even in pool areas or around children and pets.
Proven superior durability
Made from wood fibres and polymers, it resists decomposition, rot, discolouration and damage from insects and termites. Estimated lifespan exceeding 30 years, with a warranty of up to 25 years.

What types of wooden decking are available?
There are significant differences between the various types of wooden decking. Treated pine and teak decking, for example, fall into entirely different categories in terms of durability, maintenance and price. Here are the most common options on the market:
Treated Pine
Treated pine decking undergoes a chemical impregnation process under pressure, where chemicals are injected to inhibit fungal growth and insect attack, reducing the risk of rot and weather-related deterioration.
Strengths: good value for money, as it is generally low-cost and, if properly maintained, can last a long time.
Limitations:being a softwood, it is prone to scratches, splinters and cracks — a risk for children and pets. It changes colour and is easily damaged by moisture. Requires regular maintenance (painting or varnishing) to preserve its appearance. The chemical treatments applied raise environmental concerns. It is the least durable option among woods used for outdoor decking.
Garapa
Garapa decking is a mid-range option, offering greater durability and resistance than treated pine, but without reaching the prestige and performance of other exotic hardwoods such as ipe or teak. It is appreciated for its attractive golden tone, which darkens over time. Its density provides
Strengths: good natural stability and resistance to rot and insects, without the need for chemical treatments; attractive golden colour.
Limitations: significantly more expensive than treated pine; colour fades without regular maintenance; installation can be challenging due to its hardness and weight; may expand and contract with climate variations, leading to cracks and warping.
Cumaru
Originating from South American forests, cumaru is a dense and durable hardwood with a colour that ranges from golden yellow to reddish brown. Naturally resistant to fungi, insects and rot, it is a high-quality option, though still below the most premium choices such as ipe or teak.
Strengths:high mechanical resistance and durability; good value for money among exotic hardwoods; visual appearance similar to ipe.
Limitations:high cost; difficult to install due to its weight, density and hardness — the surface may not be smooth after sanding, and the oily nature of the wood interferes with screw or glue fixing. Significant colour variations between batches (from light brown to dark red). Without maintenance, it turns grey. Sensitive to coastal environments with high salinity.
Ipe
Originating from the tropical forests of South America, ipe is one of the most prestigious woods for decking. Its extremely high density and natural oils give it exceptional resistance to deterioration, insects and moisture — without the need for chemical treatment. It features an intense colour (dark brown) and an elegant texture.
Strengths: exceptional durability (can exceed 25 years with proper maintenance); smooth finish to the touch; dark, sophisticated colouring.
Limitations:very high price; difficult to install due to its density and weight; requires regular maintenance with oils or sealants to preserve the original colour. Availability has been declining — extraction can contribute to the destruction of tropical forests, although certifications such as FSC promote sustainable practices. Although less pronounced than in other woods, ipe is also subject to expansion and contraction with climate changes.
Teak
Teak is considered the most premium option among woods for decking. Originating from Southeast Asia, it is distinguished by its natural oiliness and high density, which give it excellent resistance to rot, pests and harsh weather conditions. Historically associated with shipbuilding, it is known for its golden-brown tone and exceptional durability.
Strengths: excellent natural resistance to water and salt (ideal for pool areas and coastal environments); superior dimensional stability; sophisticated appearance; does not require chemical treatment.
Limitations: the most expensive on the market. Although sustainably certified sources exist, historical exploitation has raised environmental concerns, and sustainable options tend to be less accessible and even more costly. Without regular treatment with oils or sealants, it takes on a silvery grey tone. Heavy, which can make installation more difficult. May show significant colour variations.

FREQUENTLY ASKED QUESTIONS
Frequently asked questions about wooden decking
It depends on budget and willingness to maintain. Ipe and teak are the most durable and resistant — but also the most expensive and require periodic maintenance. Treated pine is more affordable but deteriorates more quickly. For those looking for durability with minimal maintenance, CDECK® composite decking is the most balanced alternative.
The price varies significantly depending on the type of wood chosen, the area, the type of installation and the region. Budget-friendly woods such as treated pine are considerably more affordable than exotic hardwoods such as ipe or teak. In any case, on top of the initial material cost come installation costs and, above all, the accumulated maintenance costs over the years — a factor frequently underestimated at the time of decision.
Most outdoor woods require annual or biannual maintenance — deep cleaning, sanding and application of a protective oil or varnish. Without this maintenance, the wood loses its colour, develops splinters and cracks and can rot within a few years.
Yes. Even treated or exotic woods can rot if maintenance is not adequate, particularly in humid climates or in areas with insufficient ventilation beneath the deck. Damage can affect both the boards and the support structure, requiring partial or full replacement.
When new, wood is comfortable and slip-resistant. However, over time it can develop splinters and cracks — a risk for children who walk barefoot. CDECK® composite decking does not have this issue: the surface remains smooth, splinter-free and slip-resistant even after years of use.
Composite decking has a longer lifespan. A well-maintained exotic wood deck can last 15–25 years; CDECK® has an estimated lifespan of over 30 years, with a warranty of up to 25 years — without the need for regular maintenance to achieve that longevity.
Yes. The old timber decking is removed and CDECK® is installed using the Quick-Fix® fixing system, which adapts to different types of base — concrete slab, existing surface or areas that cannot be drilled. To find out the best installation solution for your space, request a quote.
