Will PIR bridge DPC?

    I intend to pack my subfloor joists with 100mm Recticel PIR and double tape for vapour barrier then 18mm ply. To create a fully sealed floor I will need to push the PIR between the outer joist and inner leaf which has a DPC at mid joist level and the wall below is damp.

    My question is whether the PIR will bridge the dpc in anyway if I butt it up against the damp wall or whether there is a better solution around the perimeter?

    Thanks in advance
