BOARD TYPES

Explore our range of composite decking boards by clicking on the images below. Once you’ve identified the style and colour that best suits your space, contact us to arrange a visit with samples.

Timbertech/AZEK

TimberTech / AZEK boards feature a recycled PVC core encased in a proprietary polymer blend. This construction offers robust protection against the elements and provides a variety of colour options for customisation.

MILLBOARD

Millboard decking combines recyclable polyurethane with mineral resin to form a durable core. This core is encased in a unique Lastane® layer that not only protects the board but also conceals screw heads by resealing over them, resulting in a seamless finish.

TREX

Trex boards consist of 95% recycled materials, forming a wood-plastic composite (WPC) core. A protective polymer cap wraps around the top and edges, safeguarding against wear while allowing the uncapped bottom to breathe.

EVA-LAST

Eva-Last’s Pioneer boards feature a glass fibre-reinforced foamed PVC core for enhanced strength. The surface showcases a photorealistic print, protected by a clear wear layer that ensures colour longevity and resilience.

Over 20 Years of Deck Building Experience

 

“Longevity in any industry stems from building trust, maintaining strong relationships, and consistently doing the right thing. With over two decades in deck construction, I’ve upheld these principles through dedication and ethical practices,” says Mark Behnecke, Deck Consultant.

Being appointed as an inaugural board member of the Australian Deck & Handrail Association (AHDRA) stands as one of Mark’s proudest achievements. “It’s an honour to contribute to shaping the future of our industry and mentoring the next generation of deck builders,” he adds.

Deck of the Month

The Azek / English Walnut Composite Board

The brief from the homeowners was simple, tell us where you think the pool will be best suited, give us maximum space and sunlight, make it functional, and build us the best deck ever. They basically gave us the keys to the backyard and said , ” we trust what you do “.

Mark from Sustainable Decking Co. was one of the most professional tradies that we have worked with.He always let us know when he was coming and delivered to us a brilliant deck that looks great. Workmanship A1.Thanks Mark Bill and Helen Fell.

Built a huge deck out of Millboard. Amazing product and Mark is an amazing installer. Mark maximised any wastage of the board and went above and beyond to ensure longevity of our deck. He treated our job like he would if building in his own backyard. Thank you.

Mark and Daniel did an outstanding job replacing our old wooden deck and front step with one made from Azek/ Timbertech composite materials. We were kept fully informed throughout about any minor modifications/ adjustments that were needed and were always consulted about the various options available. Mark arrived on time every morning and was a complete professional in every respect, from quotation through to job completion. We are thrilled with our new deck and front step and can highly recommend this company. Tim and Lisa
