New garage - slab/frame interface

[BotusBuild]

HI,

Looking forward I will be building a garage on a slab foundation with timber framing. I want to naturally get the Slab/Frame interface correct with regard to damp proofing. Below is a diagram I have put together for which I am looking for constructive critique. NOTE: I have left out the anchoring of the sole plate to the slab to keep the diagram simpler.

 

I am thinking also that the DPC, DPM and Vapour barrier should be taped/sealed together, or would the batten on the bottom piece of cladding achieve that anyway?

The batten needs to be higher up, so it doesn’t get hammered by bounce back from rainfall.

 

IMHO, the membrane should be flapping a bit there to promote drip / runoff, vs being clamped tight by the batten. Just feels like that would hold / harbour moisture too much (my simple opinion).

So move the batten up a bit, and bring the vapour barrier over the batten rather than behind it. Sounds good
