climbinggeorge Posted August 12, 2021 Share Posted August 12, 2021 1 of my neighbours (there are a few of us building in this project) has just found this issue, I'm going to check my build after work to see if we have the same issue and will add a photo Our floor build up above insulation is 50mm screed and 20mm floor finish (engineered wood), this finished height is level with the concrete door threshold and would mean the wood within the door is higher. We have at least caught this before the screed, and presumably the best idea is to grind the door threshold down - note I'm not sure on the best term if this is the threshold/cill/etc Just thought I'd see if there are bright ideas that I'm missing?

PeterW Posted August 12, 2021 Share Posted August 12, 2021 What thickness is the insulation in that floor build up ..? Link to comment Share on other sites More sharing options...
climbinggeorge Posted August 12, 2021 Author Share Posted August 12, 2021 There's 130mm insulation underneath (membrane inbetween). The UFH was stapled into the insulation today so its ideally staying down now Link to comment Share on other sites More sharing options...
markc Posted August 12, 2021 Share Posted August 12, 2021 When you say wood within the door, I presume you mean the frame? And what door, sliders, bi fold etc? a sketch would help Link to comment Share on other sites More sharing options...
climbinggeorge Posted August 12, 2021 Author Share Posted August 12, 2021 Highly artist drawing as below. I think it will just have to be a high threshold (apologies as I wasn't clear the wood was regarding the engineered wood floor finish) or we grind it down so we can lay it flat Link to comment Share on other sites More sharing options...
ProDave Posted August 12, 2021 Share Posted August 12, 2021 At least one door will have to be level access, so lay a thicker screed to raise the entire floor a bit, or grind down the threshold of at least one door. Link to comment Share on other sites More sharing options...
Temp Posted August 12, 2021 Share Posted August 12, 2021 Example part m door threshold. Most people design out the internal ramp/"transition unit".. Link to comment Share on other sites More sharing options...

climbinggeorge Posted August 17, 2021 Author Share Posted August 17, 2021 Thanks all. The builder has put his hands up about it being the wrong height and will sort - cill grinding and at their own time/cost Which means I don't have to reach a decision or alternative and can concentrate on the other N+ items currently being juggled Link to comment Share on other sites More sharing options...
climbinggeorge Posted August 24, 2021 Author Share Posted August 24, 2021 As a final update for anyone that has a similar issue , it turns out that grinding it out has the potential to loosen blocks and cause new issues. Final plan is to just screed, then stick a solid wood or metal threshold on it (something like this https://www.weatherbar.co.uk/product/metal-coverplates/ ) Link to comment Share on other sites More sharing options...
