ABSTRACT:
A method of preserving timber from decay liable to arise in the presence of moisture, e.g. in railway sleepers, comprises forming cavities in the timber at appropriate points and inserting in each cavity a plug which has been fused into a monolithic element consisting of a water-soluble wood preservative such as boric oxide; the wood preservative diffuses into the timber from the plug, to establish a zone protected from decay, more slowly from a fused than from a compacted plug.
