ABSTRACT:
Method for suppressing borer attack and accompanying erosion in a marine structure such as a pier or dock, and a borer-immune structure resulting from application of the method. The method features steps for encasing the exposed surfaces of a wooden marine structure with a plurality of rigid plates sized to the surfaces to be encased. Steps are provided for supplying a water-resistant sealant at predetermined regions on the plates such that the sealant may be spread over predetermined portions of the structure surface and the plates by clamping the plates and sealant to the marine structure with a corrosive resistant fastener. The method also preferably includes steps for providing the encasing plates with sealant-locating furrows at the plate faces that mate with the marine structure to be encased, the locating furrows being provided for receiving the sealant at a prescribed location relative to plate borders and for pre-measuring the amount of sealant to be applied. The borer-immune structure features a plurality of rigid, pre-sized encasing plates clamped to the surface of an underlying wooden marine structure by means of corrosive-resistant fasteners, the encasing plates and marine structure surface further including a layer of water-resistant sealant spread there between at predetermined locations of the plates and surface proximate the plate borders by clamping. Additionally the encasing plates preferably include furrows for receiving and pre-measuring the sealant to be applied.
