Ground floor DPM nightmare... what to do?!

[aforbes]

hi @dazlight where you say "use a good vapour underlay" do you mean just do this without digging up the floor and doing the 2x10kg again (they basically didn't put enough down)?
And do you mean MVS/fball F78 / F77 over what's there atm OR dig up and start again? (knowing we can't go much higher with what's there atm...

 

[dazlight]

Fill any holes , f78 3 coats , then underlay, timbermate excel or similar

No need to dig it all up.

I think this will bring the level too high sadly....

@dazlight @crazydaze

have discussed with the company and we think a solution might be to bash out any bossed bit and fill.
Do another 20kg Ardex DPM1 over whole space and another layer of Ardex NA.
Around the external door we frame in a low lying doormat, and at the other 5 opening we will have to have some sort of profile to that there's not a 20mm step.....
Anyone see any issues with this?
Or are we definitely better to take it all up and start again??
