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?

It may be unusual, but we have designed a precast concrete product in for our ground floor. A bit more expensive than beam & block, but It has the following key benefits: has insulation already attached to its underside can be installed by manufacturer in a day and then ready for next stages puts the concrete of the floor inside the insulated envelope increasing the insulated thermal mass Due to some Made Ground on site and not wanting the vagaries of Ground Gas well testing, we decided to incorporate a gas membrane into the design which replaces the DPM. This gas membrane will be installed above the concrete floor and then ultimately have screed over the top. There is the option to do perimeter first and then infill, but cheaper to do all as one. What I am wondering is how I leave all this for the subsequent year or so as the rest of building works goes on. Options that spring to mind are: Just do perimeter and leave concrete slabs exposed (probably grouted), infill later Do full gas membrane and cover with full depth of screed (minimum 75mm) including underfloor heating pipes Do full gas membrane and partial cover with screed (? e.g. 30mm ?) to protect the gas membrane I expect people who have used Beam & Block and a gas membrane have faced the same quandary, so it would be great to get some pointers.

Do I need to be concerned about 3-5mm height difference between the blocks and beams in my sub floor? The plan is for a DP membrane (not sure of thickness), 200mm of PIR foam, ufh in 50-60mm concrete screed, Luxury vinyl tiles. Options I see are: Do nothing 1200 gauge DPM Dry sand Leveling compound Other? Thanks
