Hi guys

Were thinking about renewing our caravan floor as we think its abit spongy in certain parts, what say you all???

Thanks

Sounds like delamination.   You don't renew it, you repair it.  Michael has done a lot of good posts on this.    Try a search.

my version for what its worth

hi,delamination...frightening no if you set out your stall and take your time.this is not a two hour job as stated,when you have finished you will know why they charge so much at the caravan repair shop.i have just done ours a few months ago.i will go through the steps best i can.ours had gone in two places,next to the door entrance and next to the sink four feet away.you will find that delamination is where the floor is used most.ie next to the sink and the door entrance.first decide how much delamination you have,ie.2 feet (old school) or 6 feet,this information is required when you go to order your epoxi resin mix.one mix will cover about 3 feet by 3 feet.got mine from barrons £25 for both tins.you also need a large syringe to inject the mixed epoxi resin.this will also sell.also the chemicals (glue) are called apollo 1 and apollo 2.i think the code is A8136.the small tin is the hardener and must be used in the time on the tin.the first thing is to remove all carpets or lino.second(must) tape up all joints and the cowls under the caravan .use a good tape.ie brown packing tape,3 in wide.if you dont the glue will run out on to the ground outside through all the seams.you will not know until you see a pool on the path..third ,support the floor under the van in some way so it cannnot bend when pressure is placed on top,do not push up the floor.you can damage the fittings inside.use wood blocks stacked up just touching the floor on the underside in the same place as the delamination.fourth find a sharp 10mm drill .you need to buy 10 mm round wood to cut and plug the holes,sold in 6 foot lengths.this needs cutting into plugs,half inch long and sanded down at one end to make it go in easy.the next step is to do a test hole,find a place that has no gas pipes on the underside.slowly drill one hole until it only just touches the plywood at the bottom.DO NOT DRILL THROUGH.tape up the drill at this depth,use plenty of tape to stop the drill going deeper than it should.mark out the area of delamination,black marker,in a square grid pattern of 4 inch each way .when finished you will have a large square full of holes to the size of the delamination.ie.3 x 3 feet.clean away all and any dust or shavings.have a large polythene bag ready to put over the square,the glue does not stick to polythene.you need a tin  or old pan to mix into of the correct size for size of mix.a clean strong stick to stir the mix.only mix what you need within the time allowed.start at the rear end injecting the holes one by one until it flows out then plug with the wood plug.when finished ,place poly bag over all holes.put a heavy weight on top ie.wheels and tyres or gas bottles.leave for 24 hours to dry.sand down all plugs until smooth.you must wear a mask for the fumes and open the windows when you are doing the job.rubber gloves are handy too.CHECK UNDERSIDE FOR GAS PIPES BEFORE STARTING.wish i could type. thought this may help

We have this problem too - just for an idea, how much do dealers charge & what happens if you leave it?  Does the floor drop through?

i stand corrected on this i believe its about £450 at the dealer.as to the floor.think of it as an icecream sandwich there is a thin ply on top,a thin ply on the bottom,and in the middle is the foam filler.what happens is the top ply comes away or unglues from the filler foam and lifts up.this will happen in the most used places ie.doorway,in front of the sink unit.before the floor drops through.not likely. the lifting will spred from one end to the other.it happens on caravans of 12 month old too,found at first service.
