Hello
I am using limecrete to created an insulated, non combustible base for a constructional hearth.
The back of the fireplace is an external solid wall. It has an old ?rubber (1920s> DPM in it which is functioning.
However if I pour the screed where planned it will bridge the DPM.
What is the correct detail here?
Add a new DPM vertically behind the screed over the first row of bricks above the existing DPM?
Or something else?
Thanks!
