What is a composite terrace?
A composite terrace is made up of boards manufactured from recycled wood fibers and polymer resins. This blend creates an innovative material that mimics the appearance of wood while eliminating its flaws: no splinters, no rot, no treatment required.
Composite boards are available in various shades and finishes, with or without grooves, mimicking natural or modern wood. They are installed on a ventilated structure (supports, aluminum or wood joists), ensuring excellent stability and longevity.

Frequently Asked Questions – Composite Decking in Belgium
Is composite really easier to maintain than wood?
Yes. Unlike natural wood, composite boards do not require sanding, oiling, or antifungal treatment. A simple cleaning with clear or soapy water, once or twice a year, is enough to maintain their appearance. Additionally, they do not warp and do not produce splinters, making them ideal for families and poolside areas.
What is the lifespan of a composite deck?
Depending on the quality of the material and installation conditions, a composite deck can last between 15 and 25 years, or even longer. High-end solid boards offer exceptional resistance to moisture, UV, and temperature variations, making them a reliable long-term solution in Belgium.
What is the difference between solid boards and hollow boards in composite?
- Solid boards are more robust, more stable, and better suited for heavily used decks or installations on pedestals.
- Hollow boards are lighter and more economical, ideal for low to medium traffic decks. They require a perfectly ventilated installation to avoid moisture stagnation.
The choice depends on your project, budget, and environment (sun exposure, humidity, intensive use or not).
Is a composite deck suitable for installation on pedestals?
Yes, composite is perfectly suited for installation on adjustable pedestals, provided you choose a solid supporting structure (aluminum or treated wood joists). This method avoids heavy masonry work and allows for good ventilation under the deck, which is essential for its longevity.
What is the price of a composite deck in Belgium?
The cost of a composite deck depends on several parameters (type of board, surface area, structure, finishes). On average, you should expect between €110 and €190 per square meter, including complete installation. This price includes the supply of boards, the supporting structure, installation, and finishes. A personalized quote is always recommended for an accurate assessment.
