Threshold Arrangement and DPC / DPM

[Daddyzord]

Was thinking of the arrangement below to continue the dpm / radon barrier that is under the interior concrete sub floor to the outside with a view to creating as much of a barrier to water ingress as possible 

 

A forward draining 3 panel sliding door rail  ( shown by osb ) sits on top. 
Exterior ground level is the Red line / top of conctrete block.
Interior level ( Green line ) is 100mm above the exterior.

 

I was also thinking to bond an additional small dpm upstand to extend up behind the aluminium door track internally.

 

Having a bit of a wobble about how well bonded / stable the single row of brick will be on top of the dpc. I was thinking of using a very thin layer of adhesive to bond the dpc down to the blockwork first.

 

Would really appreciate any input on this.!
