I've put some cheap carrier type bag plastic over it to try and stop even more ingress.

The DPC is intact .

Yes, it was built in August and has been left uncovered and exposed to weather since then.

Hi, I'm hoping for some advice. What problems might I encounter if I build a conservatory on top of an existing dwarf wall that is soaking wet and full of rainwater inside it's cavity? Should I wait until spring when it's completely dry, or can I build upon it now? The dwarf wall consists of red brick on the outer, insulation in the centre (but it has a 2cm gap open to the weather all the way round) and thermal blocks on the inside. Will I get damp problems or some other problem I have not thought about if I put the conservatory on top of it now, rather than wait for warmer dry weather? Thanks.
