Dpc question

[Deluks]

You don't need two DPMs, is this house built in a river?

The weight of concrete will push the dpm against the wall, as long as it meets the dpc you'll be alright with a mastic bead behind it.

lol yeah its not in a river but below the outside road level and always had a history of rising damp as it was my late grans house so i kind of want to make sure i fully solve the issue
