I have checked my van again and the delamination is briefly....horrendous
Would it be worth stripping the van and re-laying the whole floor.......
The area from the kitchen area to the rear of the van all appears to be "spongy"
I have checked the underside of the van and all appears ok except for 1 small area near the nearside front support (wood rotten but not the main frame just the "treated" plyboard.
Also because of the area and urgency I am looking at using the expanding foam filler, and weighting down the floor, that is if, complete replacement is either too difficult or too expensive.
Other option is to sell the van on Ebay and buy a replacment van, letting the buyer know ALL the problems.......
my 5 birth was delaminated from the kitchen/fire area all the way to the back.....its a few hours work (1/2 day) to do, but well worth it.......make it good........its well worth it.
Hi Sprouty , i wouldn't use expanding foam , i'd buy the proper stuff if i was doing a large area , do a search for Delamination you'll find some good posts covering everything you need to know .
There is a way to drill a matrix of small holes (2 mm each, 2 to 4 inches apart, check that) ) from top to the bottom layers. Than with an injection needle in ject expoxy resin to fill up on each spot, filling up the empty space in between. By withdrawing (vacuum) a little bit at the end of each injection when retracting the needle, one does not get resin on top of the floor. Once the whole relevant surface is injected put weight on the surface and let it dry. This way upper and bottomlayer of the floor become bonded again, durably. There must be several descriptions about this procedure with images in English, but I only know a Dutch source.
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
