A couple of questions.
1. Doesn't a DPC make a weakness in the wall, or is the material such
that the mortar keys into it for a good bond ?

Yes.

2. Is it better to use a waterproofed mortar and blue bricks ?

Your choice. Plastic is chheepp

3. When inserting a DPC, is the joint thickness between courses usually
still 10mm, or is it thicker ? I need this for the plans.

Uusally almost double. Is that really an issue?

TIA,
Simon.
