Hi

I've got the bouncy floor syndrome that I've got to repair. I've read up , got the kit but I could do with knowing the rough thickness of the ply that's used in an old abi ace globetrotter if anyone could help ?

Thanks

you would of got wooden pegs with the kit.
Drill through the top 5mm of ply board through the polystyrene gently until you feel the bottom ply once you have injected the resin knock in the wooden dowel it should fit flush with the floor if it protrudes when dry cut it off with a sharp chisel give the floor a light sand.
if it is a really soft area you may need to put a weight {leisure battery}on top as the top ply can rise.
Don't forget to tape up under the van floor any joints .

I'm not sure why as long as you only drill through the top sheet and touch the bottom one all should be fine. I drilled the top and then pushed the stationary drill bit down through the foam untill I reached the base and marked the bit with a piece of masking tape, this will show you how deep to go and no more. I also gaffer taped any seam underneath the area being worked on to stop the expanding foam oozing out onto the concrete below.

Similar to Pickled Onion but I used a stop collar on the drill bit to prevent the bit going all the way through. I'd put cheap plastic dust sheets under the van, its surprising where the solution can ooze out of. Be aware that the water pipes if they go across the van in the floor may have been laid diagonally.

Thanks for the reply's , didn't realise it had polystyrene in between the wood. Checked the pipes , they all go down one side of the caravan. The area that I've got to repair is basically right in the middle of the floor between the sink / cooker and the heater / cupboard unit , so clear of everything.

Thanks again

The 'foam sandwich' between the floor section gradually gets squashed down in the area which gets most traffic, hence the door, sink, fridge and cooker are the most affected areas. The top plywood panel just springs up again but it leaves a void and it's this area of no support that gives the spongy feel. There are some wooden spars every so on (you will find out where they are when you start drilling your grid patern) but there aren't enough of them in these heavily tramped spots.

Plan everything before you start, watch videos on YouTube to get the knowledge of what to do, read other's blogs and have everything you will need to hand. Find the area of the floor that needs the work and draw a regular 3 or 4 inch grid pattern to indicate where you need to drill. Avoid the spars beneath, no work needed as they are doing the support. Keep it clean as you work, it's easier to do then than when it's set. Do it in a very well ventalated area so doors and windows open to allow the fumes out. Good luck.

Dave

Well git the floor done during the last school holidays ( I work school term times ) ended up drilling 80 holes. Didn't expect the adhesive to expand quite as much as it did , but it's done , cleaned back smooth and carpet refitted. That's the bit in front of the cooker/sink but I think the bit in front of the door my need doing in the couple of years.

Thanks for the help guys , Adam

Well done Adam

Yep, the expanding foam needs to be a bit lively to get into all the voids between the floors. The 2 pack version can be so aggressive you need to restrict it's expansion with weights on top and blocking beneath or it will bow the plywood out top & bottom.

Hi Dave

I did read about that possability so I had some axle stands and a jack under the floor to stop any flex.

Hi Adam, good man, it's always good to be aware of any drawbacks and be proactive, less unpleasant surprises that way.
Forums like this one are invaluable, they pass on so much experience and information freely so that almost any job is managable by most practical people. Glad you've got it done without too much hassle.

You mentioned that you will probably have to do a bit more in another area or two at a later date, that seems to be the norm. The good thing is you will find it easier and quicker now that you have completed the first one, plus you have saved a great deal of cash in the process.

Dave.
