Okay - I knew the floor was a little spongy when we put the van away for the winter...

The van is an 1984 Bailey Pageant Maestro D - 5 berth - no damp anywhere!

Picked it up to day, and having read all I could on sorting out a delaminated floor, I was expecting to find a wood/insulation/wood sandwich. However, all I find is a wood/foam-insulation layer.

The problem is that where the insulation sits on the subframe of the caravan the insulation has become compressed. My question is do I go about sorting the floor in the same way - by drilling and injecting a resin or do I need to do something a little different?

Thanks in advance.

how big is the area         regards brian

Brian, it is the usual area from the door to the sink opposite, so 0.6x1.5m.

Thanks for replying

Could it be packed up with pipe lagging the good stuff.

It's odd that it hasn't ply on the bottom.

There is definately no ply under the insulation/foam. I'll try to up a photo at osme point so that you can see teh construction.

Paul, as to packing it would it be safe to lift the florr from underneath with a trolley/bottle jack and try to pack it that way?

Thanks all, Steve B

Steve, is your Bailey the old style of build (ie not sandwich type construction)? I had a Marathon built the 'old'way, that had a solid plywood floor with polystyrene stuck to the underside of it, so when you looked underneath it was polystyrene covered with a (loose) plastic membrane. That floor used to move and creak, but just movement between the panels.

Try drilling a small hole right through, you should be able to ascertain it is sandwich construction or not.

Vernon87 - you are spot on, black underside to the polystyrene, with a layer of plywood on top.

So what my options? Is packing between the subframe and the compressed polystyrene my only option - other than replacing the complete board?

Thanks

Vernon - thanks for the tip.

I've got an Aluminium chassis. So can I use the plywood idea and just bridge the chassis members with ply or would this cause me too much of a lift problem as it will lift the floor above the original level?
