Next they tested for Trametes versicolor (a white rot fungus), Tyromyces palustris (a brown rot fungus), subterranean termite, and marine borer
, and the results showed that among the three tested woods, pine had the greatest resistance to white rot and brown rot fungal attacks, and the polystyrene wood had much greater resistance than untreated wood to brown rot fungi, white rot fungi, subterranean termite, and marine borer
However, it was revealed that the pilings of the pier were severely comprised by Marine Borer
Worms and had become unsafe.
Deterioration of timber members is also due to impact damage, longitudinal and lateral forces, overstressing, drift/ice, poor construction details, insect and marine borer
damage, and fire.
attack was most severe at Townsville, followed by Cairns and then Bundaberg.
Among its credentials, Boswell has been extensively involved in the Port Authority of New York and New Jersey's Marine Borer
Monitoring Program over the last six years, providing the Port Authority with a tremendous amount of timber core sampling data and other information related to marine borer
biodeterioration rates of attack in various types of treated and untreated wood structures.
ACZA treated samples displayed significant mass losses over the 7-year exposure period even though no marine borer
attack of the higher retention samples occurred.
If a Level III effort of inspection is required, specialty equipment may be needed such as a waterblaster for cleaning large surface areas, or hydraulically-powered coring tools for taking timber samples to assess marine borer
One trade-off to this environmental benefit is a significant increase in the amount of marine borer
activity within these same coastal waters, equating to widespread damage to marine timber infrastructures.
The major visual defects were splits, decay, and marine borer

and Timber Piling Options (Victoria: CSIRO, 1986).
attack and eat wood, steel will rust and corrode, vinyl will degrade from ultraviolet and concrete will deteriorate over time as the rebar starts to corrode.
