A glued-in-rod wooden structure includes a prepared hole for sealing voids which may be open to the prepared hole. In one example, the prepared hole is filled with an expanding foam which at least partially fills and seals the voids open to the prepared hole. Thereafter, the prepared hole may be enlarged by drilling to its final diameter for receiving the rod. Any voids in the enlarged hole remain sealed by the expanding foam.
