I've been asked to do a 50mm deep fill over wet ufh because they've had such a bad time with 2 builders ripping them off that they have no confidence anymore and near 15k down the drain already... I was originally down to do the top screed level anyway ready for the tiler so I'm thinking a sh*t load of renovation mixed with aggregate to fill the 50mm drop back up but wondering if there is anything else (apart from Sand & cement due to the long drying time for moisture) I could use? Pretty sure Neily has done his fair share of this sort of thing and am I right that there is something Ardex do??
I have advised them to do this but they seem to be that cheesed off with everyone other than me that they only really have confidence in myself
You can use Ardex A35 in a sand and cement screed. It will be dry enough to lay on after a day or 2. When we built the bungalow at the end of my garden, I did a 50mm sand and cement screed. I ordered it, and got it tipped onto some visqueen on the drive. Barrowed it round, and away you go. Im no concrete screeder, but with some latex over the top it was fine.
Sand and cement with Murexin speedstar curing agent, be dry in 2 days. 1-1.5% agent to 1 tonne of cement, or we offer a deep fill product called st25 which goes to 50mm cheap as chips, great coverage rates, if you need my help drop me a text.
A bloody shed load, pump would be easier and faster, we deal with cemex, breedons, euromix etc that option would be better using the curing agent
So if ordered from Cemex, would that come in a mixer, then need to be fed into a separate pump hopper ?
