We have just done our floor in our caravan this weekend and had the kit off e bay it was called 1x1.1 litre one shot repair caravan floor delamination with dowels £19.25. It has done a fantastic job and floor is now rock hard.
I did mine with one-shot & dowels to great success, it's messy but does the job. Lots of info on here on how to do it.
One tip, use plenty of dowels as they are the strength of the finished job, good luck.

Hi Jo, the floor feels springy underfoot in heavily used areas, usually near the sink/fridge/door.
It is caused by the internal foam structure between the top & bottom plywood panels compressing and leaving an air gap inside. The repair foams up inside and fills the air gap, however the dowels give the majority of the strength and long term support to the job.

The floor in my caravan had delaminated about 2 years ago and repaired it earlier this year to which I used the green one shot glue and cut the dowels from 9mm. wooden dowelling from a DIY outlet. The adhesive has worked fine and the floor now feels firm again, however, after talking to a service engineer he said that he had seen this product fail many times after 12 to 18 months and quite often requires a second repair which he recommended the twin pack (glue and hardener). He said although it is more expensive to buy it is the best treatment for a permanent repair in the long term.
did mine last night but its still spongy in parts, it either needs another go or the floor has completely collapsed internally bearing in mind the van is 1987
