Conservatory Floor - damp round edges

[Carlos8881]

Hey all - see if anybody can assist

Seems there is water ingress within our conservatory. We took over the house, in the conservatory had damaged/damp laminate flooring. removed laminate to show screed layer and found some dirt/wet ground around edges of flooring - see pictures

My partner wants put new stuff down right away - but we need to figure out how to limit/stop the damp issue.

1 - is this 10-20mm gap around edge of concrete supposed be there?
2 - is there anyway we can clear this up, to prep for putting down new membrane & vinyl.

Bit of a novice, so any assistance in layman terms would be great!
Thanks,
C

Properly focussed and oriented pics will help?
Did you dig out the loose soil that can be seen?
You have a blue membrane (a DPM) thats been stopped short - it should have been flopped up the "wall" behind the skirting.
If you clean up the soil & the last bit of laminate, and remove the skirting in pic #247 things might become more clear?
Slide a thin spatula like tool down the back of the skirting to clean break the glue & any fixing.

Updated,clearer pics - thanks for the note back - do these pics help more?

i have cleared some of the soil but it quickly get to harder material. unsure where the dirt has came from.
is it worthwhile putting a thin strip of DPM around edge of concrete and under new skirting?

Thanks

Have creepy crawlies been bringing the dirt up from your garden path ? don't want to send O.P on a wild goose chase, but it may be possible?

There was/is a load of woodlice under laminate when taken up, esp around the edges.

But would that explain why these areas are so wet/damp?

We have also done a look around for broken seals - found one - but its on other side of where most of the damp appears.

External pics would be more helpful , complete structure and above .

The problem often is that conservatories can be built without any adherence to building regulations, or even good practise. It might be best to accept that this exists and use waterproof materials, like ceramic tiles, for the floor. It's obviously a little damp - woodlice like damp.

Gotcha - looking at using Luxury Vinyl Flooring - as they are warmer than tiles at least. Just wanted to see if i could do something to limit the future impact of any damp.
Will put some sealer/filler around edges to limit ingress. Just unsure if thats best practice!

If you can get the base completely cleaned up, you'll need a moisture tolerant screed like Arditex NA, a liquid DPM application such as F-Ball F77 folllowed by another coat of moisture tolerant screed before you can lay LVT to the area.

Those images are typical of poor quality low end conservatory construction. It looks like the source of the problem lies with condensation as it's forming around the edges (where coolest) and is prevalent in conservatories, which are prone. Very little of the overall connie budget is dedicated to the base. Hence loads of problems. Most connies are little more than glorified sheds and are only good for storing redundant gym equipment and discarded bread-makers.
