I need to pour over 2000 sf+ of  subfloor asap raising +/- 1.5″ and was planning on using levelrock. I thought I had the job setup but the sub never gets back to me and there are very few levelrock subs in my area and the others I talked to were either too busy or stupid pricing.

So, does anyone know an alternative product who I can search for qualified installers for? 

I don’t want gypcrete as I have heard a lot of dusting issues can occur.

Engineered wood flooring will be glued to the finished surface.
