CDECK Original – Composite decking for outdoor spaces

CDECK Original is a semi-natural product, which means that slight variations in colour and texture may appear over time.
During the first few months after outdoor installation, the colour will gradually change until it stabilises. The final tone will be slightly lighter and more natural than the original colour due to water absorption in the wood fibres. Once stabilised, both colour and texture remain practically unchanged.

Yes. Slip resistance: OK — Class 3 (EN 15534), as per the DoP.

Yes. CDECK Original is suitable for pool areas, including chlorinated and salt water environments. As with any outdoor decking, avoid prolonged contact with concentrated products.

Yes. Like any outdoor decking, CDECK Original warms up in the sun; darker colours heat up more than lighter colours. Compared to timber decking in a similar colour, CDECK may reach slightly higher surface temperatures, depending on solar exposure, ventilation and installation conditions. Hollow-core boards tend to heat up less than solid boards, as they allow some internal ventilation.

CDECK Original has an estimated service life of over 30 years, under recommended use and maintenance conditions, with a warranty of up to 25 years (please refer to the applicable warranty terms and conditions).

Advantages:

• It offers better mechanical performance — with high-strength hollow-core boards compared to many hollow-core alternatives and even some solid solutions — due to the formulation and production method. In the DoP, the bending strength (EN 310) is 48 N/mm² (hollow-core) and 57 N/mm² (solid).
• Boards can be custom-made (between 1.8 m and 3 m) to better suit each project.
• Greater dimensional stability and better abrasion resistance.
• Wide colour range (6 options).
• Hollow and solid boards share the same configuration, allowing you to mix both types within the same installation.
• Broad range of profiles and accessories, offering solutions for almost all installation scenarios.
• Patented fixing system that saves installation time, using only one screw per board and allowing individual board removal thanks to the intermediate PRO clip.
• Uses PVC or aluminium joists, ensuring high stability and durability.

Disadvantages:

• Usually involves a higher initial investment.

No. As a WPC product containing wood, permanent submersion may cause irreversible changes due to excessive water absorption.

Yes, provided that:

• a braced structure is used, as described in the technical data sheet;
• the ground is compacted in the support areas;
• the lower air cavity remains unobstructed, typically achieved by using a geotextile membrane.

The CDECK fixing system is unique and patented:

• Very easy to install and remove thanks to its click-in design.
• Requires only one screw per board.
• Includes several types of clips for different situations, including one that allows individual board opening — to access drainage, inspection chambers or simply to perform deeper cleaning.
• Allows the decking to float, improving adaptability to dimensional variations and ensuring better long-term stability.

Maintenance consists simply of periodic cleaning to maintain its appearance and prevent the accumulation of debris.

It should be washed using a pressure washer (max. 150 bar, 30 cm distance),
always cleaning in the longitudinal direction of the boards.
