How to choose the right decking tiles

Wooden decking tiles are suitable for covering an existing surface, such as a concrete terrace, balcony or path, without building a joist framework. They can be laid in a few hours and moved if needed.

It is not suitable for direct contact with the ground or for ground that remains damp: Douglas fir is Use Class 3, not Use Class 4. On natural ground, provide a bed of compacted gravel and packers, or a concrete slab.

Laying advice

Base: lay the tiles on a flat, stable surface with good drainage. The most common option is a concrete slab fitted with adjustable pedestals, which create an air gap and compensate for unevenness. On compacted gravel, packers are sufficient.

Gaps: leave 2 to 5 mm between tiles to allow rainwater to drain away and the wood to expand and contract.

Layout: align all the slats in the same direction for a linear effect, or alternate their direction from one tile to the next for a chequerboard effect.

Cutting: cut with a circular saw or jigsaw, then protect freshly cut edges with an outdoor finishing oil. Along a garden border, a geotextile membrane beneath the tiles helps limit regrowth.

Care and protection

Supplied untreated, Douglas fir naturally turns grey within 6 to 12 months without losing strength. To retain its pinkish-brown colour, apply an outdoor wood saturator when laying the tiles, then every 1 to 2 years depending on exposure.

Clean the decking tiles twice a year with a soft brush and pH-neutral soapy water. If moss or lichen appears, treat it with a product suitable for outdoor wood before reapplying a wood saturator. Check the level of the pedestals or packers every year.

✓ Clear wood saturator: protects without changing the wood’s colour
✓ Tinted wood saturator (grey, teak, honey): to coordinate the tiles with garden furniture
✓ Outdoor hard oil: penetrates the wood and helps limit staining

Frequently asked questions

What is the difference between a wooden decking tile and a duckboard tile?

They are the same product: a decking tile made from wooden slats fixed to crosspieces. This Douglas fir duckboard tile measures 50 x 50 cm and is 5 cm thick, with slats nailed to wooden crosspieces and no clips or plastic supports.

How many tiles are needed for a 12 m² terrace?

You need 48 tiles: 4 tiles per m² multiplied by 12. Add 5 to 10% if the area has corners or requires cuts around obstacles. For a rectangular terrace with dimensions that are multiples of 50 cm, the calculation is straightforward.

Can these tiles be laid on an existing concrete terrace?

Yes, this is the best setup. Lay the tiles on adjustable pedestals to create an air gap beneath them: water can drain away, the wood can dry, and the pedestals compensate for the slope of the concrete slab to create a level surface.

Are these wooden decking tiles suitable for a balcony?

Yes, provided the balcony can support the weight. Each tile weighs 4.5 kg, or 18 kg per m²: for a 6 m² balcony, allow for 24 tiles weighing 108 kg. Have the building manager or builder confirm that the balcony can support this load before ordering. Laying the tiles on pedestals is still recommended for drainage.

Why choose a Douglas fir tile rather than one made from tropical hardwood?

Douglas fir is a French wood species processed in the Massif Central. It is naturally durable to Use Class 3 for outdoor use without ground contact. Tropical hardwoods are denser and more durable, but also heavier and more expensive. Douglas fir is suitable for a terrace laid on pedestals or a concrete slab.

Is Douglas fir turning grey a defect?

No. This is a natural change in outdoor wood that occurs within 6 to 12 months. UV exposure and rain turn the surface grey without affecting the wood’s strength. To retain its original pinkish-brown colour, apply a wood saturator when laying the tiles, then every 1 to 2 years.
