Preservation of structural timbers
Mr P. A. Campbell, of Vermont South in the State of Victoria, Australia, has written voicing concern at the statement appearing on p10 of BS 5589 to the effect that ‘the heartwood of radiata pine is treatable’. He believes that this information may be misleading and, if not modified, could lead to the premature failure of ‘significant
engineering structures’:
Among other uses, treated radiata pine is being used for crib retaining walls in the UK and the untreatable heartwood should fail within a few years. Do any of our members have any experience of this?
