DPC too narrow to attach membrane to!! Any ideas

[DaveRave]

My so called 'professional' Cornish builder has used the wrong size DPCs on my wall therefore there is not any overlap for me to attach my membrane to. He has used a 100mm DPC on my front wall ..nothing spare to attach to the Visqueen. Also the wider internal walls have the same problem. See the pics. These walls are on a slab which sits in the ground....no DPC. How can I tie my membrane into these DPCs?

Cant you get HIM to sort it out if there is a problem?

That is the normal width. The dpm is usually lapped over the dpc.
