Yes after a week after the person thought it was done and plastered over the
foam it suddenly pushed a lump of plaster out and formed what I can only
describe as a bubble gum like structure poking out of the wall by the window
the foam was filling a void near.
I hate the stuff.
Its like some kind of alien organism.

The flooring runs under the kitchen units all the way to the wall. A
laminate fitter examined this and suggested that rather than lifting and
replacing the plank it would be possible to drill a small hole, squirt in
expanding foam and then weigh down the floor until it had set.

Expanding foam when expanding exerts a large force on constraining
materials and is quite likely to lift the floor no matter what you try
to weigh it down with. Moreover, in a confined space it will not set
quickly and could easily continue to expand for several days.
