Two profiles
Hollow and solid, and you can mix them on the same deck.
Hollow and solid composite, with a grooved texture
The composite decking that has always done the job: a grooved texture, six colours and two profiles to choose from, hollow or solid. Hard-wearing, versatile and low-maintenance, it suits any kind of outdoor space. Lay it yourself or leave it to your usual installer.
Sun, rain, chlorine, salt and daily use. CDECK Original® is built to stand up to the weather with minimal upkeep: simple cleaning and maintenance is all it takes.
Hollow and solid, and you can mix them on the same deck.
The classic finish, the one that never dates.
Around a pool or on a restaurant terrace. Class 3, the highest rating, certified in European Technical Assessment ETA 26/0031.
No knots, no splinters. Children can run across it and nothing happens.
It copes with moisture and salty air, if you live near the coast.
The shade settles over the first few months and stays that way from then on. UV additives keep it from cracking or fading over the years.
Insects and termites stay out. So does biological decay.
January cold or August heat, it makes no difference.
With the patented Quick-Fix® system: a single screw per board. It goes down fast and lifts up without breaking anything, if the day ever comes. Take a look at the fixings and finishing trims too.
Cut it and drill it the same way, with the tools you already have.
From responsibly managed forests, and 100% recyclable.
Both come with the same finish and colours. The difference lies in the structure and in how demanding the project is. And yes, hollow and solid boards can be mixed on the same project, keeping the same finish.
| Criterion | Hollow | Solid |
|---|---|---|
| Dimensions | 2300 × 140 × 24 mm | |
| Inside | Hollow, with air chambers | Solid, no cavities |
| Weight | Lighter, easier to handle (5.58 kg) | Heavier (9.58 kg) |
| In the sun | Heats up slightly less | Heats up slightly more |
| Impacts | Stands up to normal use | Stands up better to impacts |
| Best for | Most terraces and gardens | Areas with extreme conditions (severe cold, high moisture, heavy impacts) |
For a domestic terrace, the hollow board is more than enough. Solid makes sense when the site asks for more: a busy commercial space, a very damp area or harsh winters.
CDECK Original® uses the patented Quick-Fix® system, with a single screw per board. Simple, quick installation, whether you do it yourself or work with your usual installer.

Slightly, and predictably. It is a composite with visible wood fibre: over the first few months the shade lightens until it settles into a more natural colour, and from then on it stays put. Colour and texture remain much as they are.
Like any outdoor flooring, yes: dark colours more than light ones. The hollow board heats up slightly less than the solid one, thanks to the internal ventilation. If the space is very exposed, go for a light colour such as Beech Beige.
An estimated service life of over 30 years under normal conditions of use and maintenance, with a warranty of up to 25 years.
The hollow board works for the vast majority of projects, and it heats up slightly less as well. The solid board is tougher and makes sense in busy areas or difficult conditions: frost, high moisture. They share the same colours, dimensions and installation, so you can mix them without any trouble.
Yes to both. The surface has a Class 3 slip rating, the highest, measured wet and certified in the European Technical Assessment. It copes with chlorine and salt water, so it works perfectly around a pool. Just avoid prolonged contact with concentrated products and permanent immersion. And as it doesn't splinter, you can walk on it barefoot without any problem.
Each hollow board weighs 5.58 kg and each solid board 9.58 kg. With three boards per m², that comes to around 17 kg/m² for hollow and 29 for solid. On top of that come the joists and the fixings, which depend on the project, but it gives you an idea: it's a low weight for outdoor flooring and on a normal balcony or roof terrace there isn't usually a problem. If you have any doubts about your case, tell us about it.
Water and a mild detergent, and that's it. No sanding, no painting, no varnishing. If you use a pressure washer: 150 bar maximum, around 30 cm away and always along the length of the board. Here you have cleaning and maintenance in full detail.
It isn't just a board: it's a complete system, and that shows in the result.
• It's stronger. 53 N/mm² in bending for the hollow board and 58 for the solid one. And one of the strongest hollow boards you'll find anywhere.
• It stays stable. High abrasion resistance and very little dimensional variation over the years.
• It's fitted with the patented Quick-Fix®: a single screw per board. And with the intermediate PRO clip you can lift out a single board whenever you like, without taking up the rest.
• The substructure is the real thing. Joists in PVC or aluminium, not wood that rots.
• Class 3 slip resistance, even when wet.
• Six colours and two profiles you can mix in the same installation.
• Accessories for everything. Trims, end caps, pedestals, wedges: whatever you need, it exists.
The trade-off, plainly stated: it costs more up front than other composites. You get it back as soon as you start doing nothing to maintain it.
