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

TRADA image

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.

New research identifies additional species for use in marine and freshwater constructionnavigation-arrow

This report summarises the main findings of a collaborative research project funded by the Environment Agency and TRADA, which aimed to identify additional species for use in marine and freshwater construction.

The research examined the performance of 18 lesser-used species (LUS) tropical hardwoods, benchmarked against greenheart and ekki. Five...

Specifying timber species in marine and freshwater constructionnavigation-arrow

Historically, the UK construction industry has favoured a narrow range of tried and tested hardwood timbers for use in marine and freshwater applications.

 

Over-reliance on a small number of species is not compatible within sustainable forest management, as certain species are being over-exploited. This is likely to reduce the...

Making the grade - A guide to appearance grading UK grown hardwood timbernavigation-arrow

This guide details appearance grades applicable to hardwood planks and boards from trees grown in the UK. It broadly follows the grading criteria set out in EN 975 - 1 but with modifications to take account of the timber availability, species, characteristics and production methods found in the UK.
