Hello! I'm new to the forum and hope to get some help with a few questions.
I have removed an old floor drain from the concrete floor in my bathroom and have a new drain installed. I now need to cast the new drain in place.
1. What type of concrete should I use?
2. How long should I expect it to take for the concrete to cure/dry sufficiently so that I can proceed with laying tiles (and possibly underfloor heating)? The floor thickness is about 20 cm with a basement below.
there is quick-drying concrete that you can apply waterproofing to after a day or so and less expensive concrete that has a drying time of 3-4 weeks depending on how thick you lay it
I have personally used Ardex A35 mix with good and quick results.... it becomes expensive if you are casting large quantities though
