DPM adjoins ground beam

[anorakdiyer71]

We've extended out , opening up back wall of house, with goalpost structure.

We had to put in a 600mm wide by 1m deep ‘ground beam’with steel cages then filling in with strong mix.
This is the hole stretch across back of original property

We have recently dug out the existing house, to get the insulation benefits and currently there's a new oversight

The ground beam in between these oversights never had any DPM

Im concerned this may be a potential issue with damp as the ground beam has no DPM

If there is no visqueen protection, it's highly likely to encourage damp.

What can we do before Celotex other than laying another dpm across ( which is our intention anyway )

Exactly that.
