Any advice on what weedkiller to use, and the best (read easiest) way to
'grout' the slabs to stop anything growing back for as long as possible?

I had similar triffids in full flower in our back yard (concrete slabs)
earlier. I adopted the following strategy.

1. blitz them with glyphosate, blitz them good and proper, wet them all
over.

2. Wait a week for the glyphosate to kill the roots then get a tool like
I have. It is basically a flat piece of aluminium in a strong hook shape
and a handle. You insert said tool between slabs and scrape out both
plants and accumulated soil.

3. Sweep it all up regularly.

4. scrape the gaps regularly to prevent soil buildup and especially at
the start of spring.
