Anyone any ideas as to how to stop this rampant weed?

Now getting into all the ground hugging plants.

Soleirolia soleirolli ?
I never realised anyone thought of this plant as a weed (honest). I have a
garden full of this stuff and actively encourage it to grow . It acts as a
living mulch on my fast draining rocky soil.
It appears to be quite well behaved and stays about a few inches high except
in really wet areas where it can be more rampant.
Having said all that I am the chap that actually likes Heracleum
mantegazzianum
