Wood polymer composite (WPC) decking, which is manufactured in the UK from a blend of wood fibres and high density polyethylene (HDPE) plastic. A low maintenance alternative to timber, it has been used in a wide range of environments including outdoor dining, leisure areas, balconies and garden decking.

The wood fibres are waste from a timber processor with FSC/ PEFC certification and the HDPE is sourced from recycled milk bottles.

Available in a range of colours and lengths, consult manufacturer for exact details.


  • 25 year warranty.
  • Fully sustainable.
  • Made to length.
  • 95% recycled content used in manufacture – 50% wood fibre and 45% HDPE.
  • 5% non-recycled additive content to improve physical, weathering and processing properties.
  • Wood polymer composite is 100% recyclable.
  • Will not splinter, split or crack.
  • Low maintenance.
  • Low moisture absorption.
  • Excellent dimensional stability.
  • A low potential for slip – wet (PTV: 37) or dry (PTV: 58).

ecodek® is resilient to changes in moisture, UV light and temperature and is highly suited to external applications as it will not splinter, does not require sanding, nor filling or preservative coatings.
