All of our decking and cladding substructure posts, joists and battens are long-lasting and boast a 25-year warranty. Unlike traditional timber, our recycled plastic or aluminium substructure provides a durable substructure that will not rot, warp or weaken over time.  

Use our plastic joists to create a sturdy and durable decking substructure using our pedestal system or can lay straight onto a hard-standing surface. Our Ecoscape plastic joists are made from 100% recycled materials and designed for quick and easy composite decking installation. The long-lasting decking substructure will not rot or splinter over time and is available with a 25-year warranty.
