TRADA has identified lesser-used species of hardwoods for marine and freshwater construction
TRADA has published guidance on lesser-known species of hardwoods for marine and freshwater construction in the new Wood Information Sheet (WIS) 2/3-66 Specifying timber species in marine and freshwater construction. Specifiers have a key role in making informed decisions on the type of materials to be used in schemes. They must balance technical requirements with environmental and cost considerations. Historically, the UK construction industry has favoured a narrow range of 'tried and tested' hardwood timbers for use in marine and freshwater applications, such as ekki and greenheart. 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 security of supply and cause inflationary price pressures in the future.
The WIS provides guidance on the technical properties of a number of lesser-used species (LUS) of hardwoods that may be used for marine and freshwater construction. It explains the advantages and risks of using timber in these environments and offers guidance on procurement. In order to produce cost effective, sustainable and long-lasting structures, specifiers must understand the hazards to which timber may be exposed and select the species with the most appropriate properties for the job. This WIS complements established design references, national or international standards and codes of practice.
