Review of TopDex Composite Decking

TopDex is among the various companies that offer composite decking as an alternative to traditional wood decks, offering a more durable and low-maintenance alternative. Since timber decks are subject to weathering, mold, termites, and warping, it’s no wonder why property owners everywhere are increasingly opting for composite decking. 

But how does TopDex compare to the competition, and what do they offer in terms of composite decking? Read on as we review TopDex’s products so you, as a homeowner, can make the best decision. 

TopDex: A Brief Intro

TopDex is a company based in the European country of Latvia and is committed to using wood polymer made from recycled materials in their products. They supply their products throughout Europe and the US and aim for a simple yet attractive alternative to timber decks. 

What is TopDex Decking Made of?

TopDex uses WPC materials, which stands for wood plastic composite. TopDex’s decking materials contain:

  •  55% wood fibres – made from wood flour, a durable by-product of wood manufacturing 
  • 30% synthetic polymers – these are HDPE, which stands for high-density polyethylene
  • 15% supplements – these are components such as paint pigments, mineral fillers, anti-fungal agents, etc. 

How Many Colours of Decking Does TopDex have?

TopDex comes in eight different colours that can be applied to any of its products. 

  • Cherry
  • Sahara
  • Cappuccino
  • Cinnamon
  • Chocolate
  • Vanilla
  • Graphite
  • Platinum

What are the Finishes of TopDex Decking?

TopDex decking can be cut to custom length and comes in two finishes: natural wood, which, as its name suggests, mimics the natural wood grain of traditional timber boards, and grooved, which provides a uniform appearance throughout. 

Choosing the finish has a lot to do with the deck’s purpose. The uniform grooved finish is ideal for commercial properties, while the natural wood grain adds a homey touch to homes and private properties. 

Profile of TopDex’s Decking

TopDex’s composite decking is hollow – providing the beams with a lighter weight than solid beams and extra durability, and scalloped – meaning that it isn’t reversible and only has one usable side. Scalloped decking is a little cheaper than non-scalloped decking and makes for an easier installation. 

TopDex’s composite decking is slip-proof, making it safer than wood boards, and doesn’t warp or fade in the sunlight. It also lasts a minimum of 25 years in prime condition, making it a smart investment to add property value. 

TopDex Lines

Alongside decking, TopDex offers a variety of products such as fencing, shutters, blinds, small structures such as gazebos and garden sheds, railings, benches, and even aboveground flowerpots.

For our review, we will be looking both at the hollow composite decking boards and the solid fence boards. 

  • Composite Decking Boards: Classic – these hollow decking boards are grooved and scalloped.
  • Composite Decking Boards: Vintage Wood – as its name suggests, these composite boards mimic natural wood’s appearance without traditional timber decking’s downsides. 

How Long is TopDex’s Warranty?


TopDex offers a 10-year warranty for its decking materials. Which is short compared to most composite decking with warranties of 25 years. It is even shorter when compared to the best composite decking warranties. Opens in a new tab.
