1970 INSPECTION OF EXPERIMENTAL MARINE PILING

The 54 Cooperative piles at Coco Solo, Canal Zone and the 273 Cooperative and NCEL experimental piles at Pearl Harbor, Hawaii were inspected during the weeks of 9 and 23 March 1970, respectively. After 7 years of exposure at Coco Solo, 9 of the 12 piles treated with creosote-coal tar showed borer attack of varying degrees of severity. Only minor attack was noted on 2 of the 18 dual-treated piles. None of the Cooperative piles at Pearl Harbor was attacked by borers after 7 years but 33 of the 207 NCEL experimental piles showed attack by one or more Martesia after 3 1/2 to 6 years. Some were also attacked by Limnoria. The most severly attacked piles were those treated with CCA-Type B, chromated copper arsenate, by a commercial treater. (Author)
