Damp course not on outer skin

[2020c]

See diagram.

Garage raft foundation been installed recently and I've the first row of soapbars around the first layer of the raft onto of the dpc.

I built up one corner 6 block high and finished for the day. Plumb and levels as can be but then remembered I forgot to put another layer of dpc on top of the soap bar.

I'm 95% taking this down when I go at it again tomorrow or is it even worth taking down and just continue building as I am seeing I've the dpc under the soap bar and under the raft in radon barrier.

I know in houses the dpc should be 150 above ground level but if I was to keep it like I have it built now, how is it possible for damp to cross into the garage floor.

You still need a pair of independent DPC's (inner and outer leaf) at internal FFL.

That is the finished floor level you see here where the dpc is under the top block

I see no insulation, screed or anything else indicating a finished floor. All I can see is an engineered raft.

It's a detached garage. No need for insulation or screed.
