Abstract: A wood preservative insert for insertion into wooden structures and a process for producing those inserts. Water is added to a dry mixture comprising at least one boron compound and at least one fluorine compound and the resulting hydration reaction binds the wood preservatives together and, once dried, results in a wood preservative insert which dissolves only on contact with moisture and has sufficient strength to be easily handled.

Abstract: The invention described is a wood preservative applicator or bandage for wooden structures such as wooden poles which wraps around the pole at ground level. The bandage comprises a inert matrix 2 which has a surface for contact with the wooden structure and has a plurality of reservoirs 3 formed therein. The reservoirs communicate with the surface of the matrix and contain a solid tablet of wood preservative chemical for supply to the matrix surface. The plurality of individual reservoirs are arranged on the flexible matrix to enable the matrix to be shaped to conform to the contour of the wooden structure. The bandage is also provided with a fastening means for securing the matrix in position on the wooden structure. The fastening means is a line of indentations formed above and below the plurality of individual reservoirs.
