Assessment of the durability and engineering properties of lesser-known hardwood timber species for use in marine and freshwater construction

This collaborative research project between TRADA, the Environment Agency and HR Wallingford investigates the strength properties of five LUS - cupuiba, angelim, okan, tali and eveuss as an alternative to the frequently used Greenheart and Ekki.

In addition, this research report identifies marine borer and abrasion resistance of a range of candidate species.
