DPC choice below Beam & Block

[MortarThePoint]

We're using Thermabeam rather than beam and block, but the compressive load under the supports will be similar. As there are concentrated loads, do I need to use a specific type of DPC? What DPC do people use for beam & block beams to bear directly on?

I used high loaf 600 mil So I could fold it out to rap the edge of the beam and sit my first course of block on

Thanks @nod

 

High load: Do you remember the brand you used? I've seen this commonly available, but no idea if any good:

600 mil: I read that as you used a 600mm wide DPC folded up over the beams, sounds like a nice approach.

If you just ask for high load Dpc 

The BM will know what you mean

One of The handiest Things is with it being thicker it’s easier to keep in place

I went with Capital Valley Plastics High Performance DPC as it is rated for 3+ storeys and I could get in next day. I don't need its gas properties, but its Radon proof as well:
