Eucalyptus is significantly stronger than oaks and mixed hardwoods in measurements of bending strength, shear, hardness and related measurements.

Wood Bending

Mixed hardwoods 1400 200 750

Field Applications:

  1. Consider specifying mat strength rather than dimension. For example, a 6.75” thick Eucalyptus mat has about the same bending strength as an 8” mixed hardwood mat.
  2. If you are engineering lifts or are working on particularly poor soils you may find that a single Eucalyptus mat is equivalent to two mixed hardwood mats.
  3. For transmission work you may find a 4″ or 5″ mat suffices given typical loads. Check out this article on testing 6″ mats for concrete trucks.
  4. For solar work you may find that a 4” thick Eucalyptus mat (roughly equivalent to a ~5″ mixed hardwood mat) is sufficient to support typical machinery weights.
  5. If you use laminated mats – three-ply bolted or glue-line mats: A ~4″ Eucalyptus mat is roughly equivalent to a five-ply 6 7/8th inch lam. Best explained visually. Book a short call for the details.
