Thanks for the reply guys, sounds like this is contested territory.
BTW guys, I am using dense blocks, so they are super heavy, if that makes a difference.
Just for clarity's sake, what do you mean by lapping here ? Would I put a 10mm bead on the DPM, flatten it and lay the DPC, and then another 10mm on the DPC followed by the block work ?The DPM is lapped under the DPC, which is laid on a 10mm solid bed.
