I have just bought a Swift 470/2, and am looking for a little advice. The floor has got quite a bulge in it around the sink area around (1/4" high!) and upon lifting the carpet it seems the wood has really badly bulged and split. I have drilled a circle out to investigate, and it seems that as the wood has bulged, someone has filled the buldge with expanding foam to stop it flexing! I was wondering about chopping a section of the floor out (probably about meter squared), and securing some new ply with battons and glue on to the foam? Luckily the expanding foam doesn't appear to have damage the insulation and is seperating easily.
The way you have outlined your repair does not sound viable as it will not have the strength to support weight. I do not think that the remaining sound plywood/foam sandwich would have sufficient inherent strength to anchor your repair.
If you repair the area by framing it with battens that are screwed and glued with epoxy, then replace the top skin using epoxy the repair will probably be stronger than it ever was in the first place.
Epoxy will not attack the foam, and has a high level of strength in its own right, so it is the perfect stuff to use.

This is exactly how I planned. Thanks very much. What sort of epoxy do you recommend and where from. Screwfix?
One last question (I promise!), the wood appears to be around 6mm thick, does this sound about right? Any known good place to by it from, or just search b&q etc?
Repair going well, but it appears the expanding foam bodge has created a real dip in the polystere floor. Is there anywhere I can get a new sheet of polysterene from?
