    Can anyone give us some advice about repairing an area of floor that has delaminated? Is it possible to do this yourself?

    Yes you can do it yourself,there is a kit available that you inject into the cavity,but am afraid it s not cheap.

    Why ever not if you have the skills and the time and if it's really serious undercover working.

    How bad is it ? How easy is it to get at ?

    I've seen this problem reported on the forums many times connected with Swift who failed to seal a joint somewhere - so you do it you need also to find why it is delaminating and cure that as well.

    From another forum

    Modern caravan floors and walls are made of sandwich construction. The floors are constituted of upper and lower sheets of thin plywood bonded to a styrofoam core, while the walls comprise the outer aluminium and the inside wallboard bonded to a polystyrene core. If the bond breaks down, delamination takes place. This is more likely to happen to the floor, which then feels spongy. The obvious sign of wall delamination is the aluminium panel bulging outwards. Both forms of delamination can be effectively cured using a specially-formulated epoxy resin.

    To repair a delaminated floor:

    1. Remove carpet.
    2. Drill holes in a matrix pattern to the affected area.
    3. Tape up any floor joints under floor to prevent glue escaping.
    4. Inject the 2 part epoxy resin into holes until resin comes out of surrounding holes.
    5. Insert wooden dowels into holes to add additional strength, similar to steel rods in concrete.
    6. Wipe up any excess resin.
    7. Allow 24-48Hrs for resin to harden.
    8. Assess treated area and if area still moving repeat steps 3-7.
    9. Once area is solid, sand back heads of dowels and any excess dry resin.
    10. Relay and fix carpet.

    Our's isn't. Half inch plywood here. There's an underfloor battery box to prove it.

    After that there is a further floor a few inches below.

    Proper job from Burstner.
