Floor delamination

[Glenn_5132962]

Has anyone managed to repair floor delamination entirely from below. ie lying under the van and drilling up into the floor & injecting the glue and plugging from below?

I ask because I really do not want to disturb the carpet. It looks like the makers installed the carpet first & built everything else over it. To get it up I would have to dismantle the bed boxes, shower cubicle, fridge & oven units. The alternative would be to cut the carpet around the bases of all these units & I know if I do this I will end up this gaps when I try to refit.

Also, is it always the upper layer of wood that becomes seperated from the foam?

Carpet under the units - I'm guessing you have a UK made caravan.

There are a number of photo stories (Eriba Owners club - German web-site) detailing the restoration of old Eriba caravans (30+ years old), and in two of those - the floor was repaired from underneath.

Floor delamination tends to occur in heavy use areas - like the doorway,in-front of the cooker, etc., - and it's always the top surface that goes first - the polystyrene core failing and breaking under use.

Yes it's a 1998 swift 5 berth. It's spongy right in front of the cooker. So if it's the actual core breaking up and not the bond between the core and the wood then there should be no reason not to attempt the repair from underneith? The only drawbacks will be trying to keep the glue in while I plug the holes? I'm prepared to try this I think before trying to get the carpet up.

Anyone any other advice?

The repair from underneath would sound perfect in this case - the areas of difficulty encountered (rough translation form the German) were making sure that they had measured correctly from the outside of the caravan , that they had checked (many times) the drill depth, that they had covered a sufficiently large area, and that you've prepared all the sealing plugs (dowels) before hand.

You also need to make sure that the floor has a (weighted) board covering the repair area to stop any bubble or distortion of the floor when you pump in the two-part resin.

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

Hi Glenn, This is the method and material for repairing de-lam from the underside of the van This is a description of the method I use for the repair of floor de-lam,

Determine the extent of the damage from inside the van, transfer the information to the underside, drill a series of 8mm holes through the first layer of ply ONLY these should be centered at 200mm over the whole area, now drill 6mm pilot holes through the insulation until you just touch the upper ply NOT through, mix the 2 part adhesive carefully and load into caulking gun supplied with kit, the mixture will stay usable for about an hour, push the plastic probe into the hole until it touches the upper ply then pull it back a 1/4", pump the adhesive into the floor four or five pulls should do it you will feel the pressure build depending on the severity of the de-lam in that area, work your way across all the holes one line at a time, when injection is complete, place boards inside van and place weights on to apply an even pressure across the reworked area, place plugs into holes,and leave for 24/48 hours. DO NOT inject to close to origanel joins in the floor!!! make sure you clean all equipment with the supplied solvent within the hour. The kit is available from http://www.theglue.co.uk/ if you need anymore info let me know. George.

Thats a great help. I'm going to buy the kit from the glue people & give it a try.

Thanks!
