Have you ever applied a 25mm screed on top of beam and block?

Have you ever applied a 25mm screed on top of beam and block? I'm talking directly to the slab. I notice that some systems allow it with bonder applied to substrate.  Were the results satisfactory?  Did you add fiber?

You would be ok with a self leveling compound Expensive Buy why?

Where is the insulation going?

When you have cambers in the beams the screed would be very thin at the high points. What is your reason for wanting to do this ?

The option is listed so I thought I'd ask, although the part about direct to slab is not indicated.  I admit it is a bad idea because grouting all of those members is what makes the floor a monolith.

Nowhere in particular, but I was thinking ground floor on a new build.

I don't know, I have to admit it was a wast of gray matter or is it grey 🙂

You would need insulation, or not comply with building regs.

This is for the Bahamas, we have no insullation requirements.

Wouldn't you want insulation to keep the cool inside, instead of the warm in?

When it's 85°F outside, the crawl space might be 65-70°F. Winter temperatures in crawl spaces are generally warmer than the outside air due to ground insulation. For us this  I guess it's a fringe benefit.
