Everything You Need to Know About Wood Slabs

Australians are increasingly turning away from dull, characterless mass-produced furniture, opting instead for custom pieces tailored to specific rooms, made from choice materials and fitted with personalised design features. Current trends are steering clear of machined, boxy furniture and towards more organic, uniquely shaped pieces crafted from salvaged raw wood slabs. This creates unique furniture, emphasises the natural beauty of local hard and softwood species and is guaranteed to last in indoor and outdoor settings with minimal upkeep. 

What are Live-Edge Timber Slabs?

Live-edge timber slabs are wide, singular boards cut from a full tree trunk. They preserve the tree’s original edge, with common imperfections such as burls, cracks and grain patterns revealing the inherent character of the wood. Slabs are sourced from sustainable harvesting or salvaging fallen and storm-damaged trees. 

Custom pieces produced from wood slabs range from dining tables and countertops to side tables and nightstands. Smaller pieces are also being turned into cutting boards, floating shelves, wall art and coffee tables. Grain patterns, colours, and distinctive features largely depend on the wood species. 

Common Wood Slab Varieties 

Australia is home to native timbers with diverse colours, grain patterns and textures that add charm and historical depth to furniture. Hardwoods are particularly sought after for their distinct properties. Common wood species include: 

  • Jarrah: Instantly recognisable for its deep, rich reddish-brown colour and interlocked grain, Western Australian Jarrah is also valued for its hardness, high density, and natural resistance to pests and decay.
  • Spotted Gum: Blending a variety of natural colours (from pale creams to grey and chocolate brown) and a wavy, interlocking grain, Spotted Gum is chosen for its extreme hardness, durability and dimensional stability – prerequisites for pieces seen in heavy-duty daily use. 
  • Tasmanian Blackwood: A premium Acacia species, often chosen for custom cabinetry and its golden-reddish browns and distinct, dark veins. Being softer, the wood is also easier to shape and work with. 
  • River Red Gum: Ranging in colour from light pinks to deep, vibrant reds, and with a moderately wavy grain pattern and distinct gum veins, River Red Gums are the most common Eucalyptus tree in Australia. Favoured for its high density and durability, it’s a common choice for larger dining tables. 
  • Marri: Native to the southwest of Western Australia, Marri is another Eucalyptus species chosen for its warm, golden-honey hues and swirling natural wood grain with numerous knots and irregularities. 

Key Advantages 

Unique Designs 

No two pieces of live wood slabs are the same. Each piece has its own distinctive shape and features such as grain patterns and imperfections, even within the same wood species. This lends furniture pieces more character. 

Durability and Reduced Maintenance Needs

Australian hardwoods are some of the world’s most impact and pest-resistant wood varieties. They’re ideal for both residential and commercial spaces and can last for decades with proper care. All that’s needed is regular cleaning and occasional oiling or polishing to retain natural colours and sheen.

Sustainable and Eco-friendly 

The wood is sourced from trees that would otherwise end up in burn piles or landfills, as well as from trees reclaimed during land clearing, urban development, or after storm damage. Using the tree’s natural shape and form also helps minimise waste. This approach offers a more sustainable and eco-friendly alternative to mass-produced timber harvested specifically for commercial use.

Customisation and Versatility

A key advantage is the option to acquire a solid wood slab tailored specifically to the space. Buyers can choose from different timber species, each with its own character, along with dimensions, colours, grain patterns, and finishes befitting the surroundings. 

Moreover, slabs are often finished with resin to preserve unique features and fill in cracks, knots and voids. They are then turned into dining tables, countertops, shelves, headboards and furniture pieces that are both practical and unique. These pieces can fit into a variety of interior and exterior design styles, ranging from rustic and traditional to modern and industrial. They can also be paired with furniture accessories such as table legs and drawer handles in various materials. 

Main Buying Considerations 

Size and thickness, timber slab moisture content, and an understanding of grain patterns and natural imperfections all contribute to pieces that work in defined settings. Slab thickness dictates the strength and visual presence of the furniture piece. Consider slabs around 3 cm to 4 cm thick for shelving, 4 cm to 6 cm for smaller coffee tables and benches, and up to 10 cm for larger dining tables. Also take into account pieces that need to be planed or trimmed to ensure a flat surface. 

Widths generally determine functionality. This can range from 40 to 60cm in coffee tables to 120cm in dining tables. And lengths dictate capacity. As an illustration, standard dining tables seating four people are typically 150 cm, while those seating eight or more people are upwards of 200cm. 

Moisture content determines the stability, durability and structural integrity of the wood slab. For indoor pieces, look for air or kiln-dried slabs with an overall moisture content between 6% and 8%. This can be measured with moisture meters. Furniture and architectural pieces used outdoors generally gravitate between 10% and 15%. A good idea is to let slabs acclimatise to the settings before they’re cut, jointed and finished. 

Lastly, grain patterns and natural wood imperfections are what add character, appeal and the warmth that no mass-produced furniture can replicate. Australian hardwoods in this respect go with dynamic and complex structures, with interlocking or straight grains, gum veins, knots and burls providing their own authenticity.
