How can I check if the DPC injection was done properly?

What is the recommended diameter of the dpc holes and the distance between them? we're going for the no warranty option so I feel the need to double check these things.thank you

On my DPC the holes are 22mm in diameter with the distance being every 110mm, however it does depend on what is being injected, as most will be smaller in diameter than my dpc.

There should be 2 holes per brick and to be effective it should be drilled on the inside aswell. Do not try to treat the internal wall from the outside as there is no way of knowing if the bricks have been drilled in the right place.
