i,ve been reading previous threads on delam. and am not sure at what stage a floor needs treating!

our 'van floor does feel slightly springy (it is not solid) but dont know if this is just the feel of walking in a van ...are the floors normally totally rigid ? having said that it has got the removable loose type carpet with cushioned vinyl underneath...im not sure if the give i feel is down to that!!!!

is there a way of checking without drilling holes????

hello Sue and John, try getting someone to walk in the van whilst the other checks for movement underneath, if you see the floor move you have delamination, i am going to do my floor this month hopefully all goes well, i'll let you know.

if it needs doing does it have to be from top or can you inject from underneath?

seems like a big job if its only from inside as our flooring goes right under all furnishings!

i know its a bit of a drag but they say the best way to do it is by taking up the carpet and injecting from inside, thats how i am going to do it, ok so i have to cut the carpet out, but its not that expensive to replace either with new carpet or i may go for cushion floor, I asked at Barrons about them doing it the price depends on how much resin they use, which they tell me its about £40 a time plus over £100 labour, they take the van in on a friday put it up on a ramp and inject it from underneath and it stays on the ramp till monday afternoon when u can collect it, so thats why im doing it myself worth a go i think.. good luck

Well worth doing yourself.....its not a major job.

Although the caravan floor repair kits are bloody expensive for a resin. I have seen ppl using expanding foam as an alternative repair kit, not tried it myself.

I used a resin made for the motor industry, a lot cheaper and sets in exactly the same way.

Like others have said, get someone else in your caravan and watch them walk over the area, if you see it sink when they walk over it its probably worth doing. The main areas to go are infront off the kitchen area and main doorway.

How old is your van, you didnt say?

how much resin would be required to do an area of approx 12 sq ft to a depth of an inch ?  Ours needs doing from door to front end of kitchen on half the width of the floor , Barrons have quoted £25 for the kit , dont know if there would be enough in one kit to do it , they never gave quantities.

it all sounds a bit more involved than i thought..............

im gonna get a quote off barrons first for them to do it before i go diving in & hacking the floor myself. If they do it it will be right .... wont it ????

Jon....get it done man......its not a big job. I eneded up injecting from the door right thro to the front lockers......it used about 6 litres off resin. The secret is drill a test hole and as it just breaks thro the plywood stop the drill and then just plundge it down and maesure how deap it is with the drill bit............ide be suprised if the drill bit falls more than about 6 or 8mm thro.......thats the void you have to fill.

You will also find as you are drilling thro that in some areas it will only have delaminated a couple off mm. If you use the stuff they sell in the caravan shops i would think that size off area may take 3 kits...possibly 4 depending on how bad it is.

Try a test area with expanding foam m8.........its a lot cheaper. Drill a 2ft square grid with holes about every 6" apart....start injectinmg at one hole, wait for it to come out the next and repate all over the pre drilled area........leave it 48 hours and i think you will find its solid as a rock.

Good Luck

cheers pal , where can i get expanding foam from ?

I dont want to do the whole lot with foam cos not sure how permanent the repair would be , but agreed, good idea to do a test piece with foam see what results i get , dont want to blow a shed load of money on a repair kit & stuff the job up especially if i need a few kits....

What size holes did you drill m8 and did you plug the holes after as stated elsewhere in this thread or just tidy them up after it had all set ?

Think the problem with our van is due to previous owners kids jumping from top bunk , (its a side dinette layout ) this is where the main damage is.

cheers.

Hi Sue & John,

It could be worth looking at caravanfaultfinder.co.uk  Click on Basics.  It would seem that there are two reasons for 'spongy floors'.   I used this site for diagnosis & cured our van floor by extra supports underneeth the floor made from 2" aluminium angle.  A relatively simple job to do.  If this would solve your problems I would be pleased to send photos' if this would help.
