Hello, we have a guest cottage built in the 70s where they framed and insulated on an uninsulated concrete slab. We have torn out all the flooring down to the slab and now plan to lay aging-resistant plastic and pour EPS concrete. On the slab, they cast on top of lecablock on which the sill rests. How should you handle the plastic on the lecablock, how to seal so that moisture doesn't move into the wall? They have extended the wall about 10-12 cm over the lecablock. Peter
One idea could be to fill up half with lecakulor that you pack. On top of that, you then lay a fiber cloth so that the EPS cement doesn't fill in between the lecakulor. Then smooth the entire surface with flow screed.
