Alexphd1 Posted June 11, 2016 Share Posted June 11, 2016 We are doing a KORE slab. How do we go about pouring the whole house slab and getting a run for a tiled wet room? Link to comment Share on other sites More sharing options...
PeterW Posted June 11, 2016 Share Posted June 11, 2016 usual way is to make a former - you can use scrap EPS - that creates a hole in the slab. When the main slab has gone off, break out the EPS and then regrade your falls into that with concrete as needed. You still need to be pretty accurate with the drains though as they need to be roughly correct as you won't have much by way of room to move Link to comment Share on other sites More sharing options...
Nickfromwales Posted June 11, 2016 Share Posted June 11, 2016 If it's a former, then the likes of Impey or Diamond only need around 25mm depth. Link to comment Share on other sites More sharing options...
Alexphd1 Posted June 11, 2016 Author Share Posted June 11, 2016 i have seen a form been done before. It was pretty deep full depth of the UFH screed (i think) but I didnt like this idea in a 150mm structural slab, but if only 25mm then i cant see it being a problem.

HerbJ Posted June 13, 2016 Share Posted June 13, 2016 I contributed to this subject on Ebuild and paste the relevant parts below: Members 78 posts Posted 15 September 2015 - 06:20 PM The foundation has recently been completed for our MBC house ( the timberframe installation starts on 21 September, Brendan leading the team) and we have a incorporated a wetroom in the ground floor cloakroom. I attach the details that we worked up and were approved by Hilliard (see the foundation layout), together with a photo which shows the formwork (a piece of EPS) and the soil pipe around which we formed a slot for the drain piping from the linear shower drain to the gulley for the wetform former recess - apologies that it is not great but you should get the idea. What we developed allows us some flexibility for installing the shower drain and the gully in the adjacnet Plant Room. We selected a ACO former with a liner drain, as it only required 25mm recess in the slab.

This approach is, however, quite dependant on the soil pipe being reasonably local to the shower tray. Did you still go with 50mm / 2" waste pipe from the shower waste ? Regards, nick. #50 HerbJ Member Members 78 posts Posted 15 September 2015 - 09:18 PM Hi Nick Yes, it should look good and it was done to future proof the cloakroom to provide a wetroom to meet LTH standards. We realised we had to do it properly whilst we were designing and installing the passive slab, as it could never be retrofiitted. The soil pipe is less than 800mm from the drain outlet and we will install a 50mm waste pipe. The formed slot should give us plenty of flexibility for achieving reasonable fall to the gulley. We looked at various former, shower traps and gullys but this seemed to be the best approach for a reasonably shallow installation without comprising the passive slab. It was realtively easy to achieve using EPS Insulation as the formwork before pouring the slab Regards, Herb #51 Nickfromwales Short cuts take three times longer.....Fact Moderators 8,182 posts LocationSouth Wales Posted 15 September 2015 - 10:19 PM For others info, Wedi do a side exit integrated waste which I'll post links to after I catch up on some kip.
