Condensation on mdpe pipe in kitchen

[gambo]

New floor and everything rerouted to allow for more space and different kitchen cabinet layout but I spotted that the mdpe pipe is wet (just below the paper towels). I did a few observations and after sticking lots of towels into the hole I think it's just condensation.

What's the best way to prevent it? Covering with kitchen cabinets will probably reduce it but shall I put some close cell foam into the hole?

Dont use foam. Just use a length of pipe insulation.

It was obviously flowing cold water - so pipe surface below dew point. If it's a concern just insulate it, with the grey pipe insulation you can pickup anywhere

My worry is that when I close it with cabinet on top the condensation may cause mould.

I've covered the pipe to see if this helps but also to make sure condensation comes from kitchen.

To my surprise the foil is completely dry on outer side but wet on inner. Does the condensation come from the ground? Or is this some dpc issue? Shall I just cover it like this?
