Hi
My kitchen tap has come loose but the board it is attached to has broken away underneath (see attached picture, taken looking upward while lying on my back underneath the sink). The board is about an inch thick. Any suggestions about how I could patch this piece to rebuild it again so I can put a new tap in? The tap at the top is completely loose as well (see picture) as the board underneath it has broken away and isn’t holding it in place.

Unfortunately I can’t remove the bench top. I would have to patch it coming from underneath the sink 🙁

Any advice would be appreciated!
