Benefits of CitiDeck®

CitiDeck® is a non-slip timber deck board designed for use in urban environments and where inclusivity and accessibility are essential. 

Originally developed to promote inclusivity at the Olympic Park, Marley CitiDeck® is now specified for many urban applications, from schools and hospitals to housing developments and restaurants. Timber decking is the most sustainable, and one of the most environmentally-friendly, hard landscaping products.

The smooth profile of Marley CitiDeck® is easy to clean, preventing accumulation of dirt, litter or food waste. Featuring two non-slip inserts with a white-coloured aggregate, there is a choice of C16 or C24 grading and both carry the UKCA and CE mark. CitiDeck® has been independently tested by the Health and Safety Laboratory.

Specifying for different sectors

Schools, nursery and playgrounds

CitiDeck® decking can be used to provide a safe and attractive outdoor space that is easy to maintain and creates an adaptable space for both outdoor play and teaching areas.

Pubs, restaurants and hotels

People love eating outdoors, especially when the weather is warm. Marley CitiDeck® is ideal for use where regular cleaning and maintenance in catering environments needs to be quick and easy.


Safety is everything, but so is accessibility. Decking should be slip-resistant and not create a hazard or a barrier for people in wheelchairs or those who are otherwise less able. Take a look at these specification considerations in more detail. 

Boardwalks, bridges and cycle paths

Boardwalks are useful where you need to provide access to an area that may be difficult to reach, such as in rough terrain or marshland. For any boardwalk, bridge, or outdoor path the surface is critical in preventing slips, but the type of decking, its preservative treatment and construction are also very important considerations.
