Big River Raw Engineered Timber Flooring

Big River Raw or Uncoated Engineered Australian Hardwood Flooring is manufactured exclusively in Australia from five layers of Australian eucalypt hardwood sheets bonded together to form a solid, stable floorboard. Each layer has its grain aligned at right-angles to the next, creating an extremely stable structure, with the top and bottom layer being the veneer of the chosen species

The special cross-ply manufacturing process creates boards with the genuine beauty of forest timbers but with greater resistance to shrinkage than solid timber boards

All Big River engineered flooring is milled from managed regrowth and plantation forest hardwoods. Big River hardwood flooring is Australian Forestry Standard (AFS) Chain of Custody certified.
