Monolithic Slab With Multiple Levels
Hello, I am thinking about building a new house and the location (NE Wyoming) points best to a monolithic FPSF and slab. But, I have been struggling mightily to understand how to create different floor levels, such as the main floor, a covered patio and entry both 4-5 inches lower than the main floor, as well as the garage floor with no drop, but a 2% slope. I basically gave up and decided it would have to be done with two pours; the main floor followed by the garage, patio, and entry.
But, then I told myself to wait a minute. The house I am in right now, built in 2015, has a very complicated post-tension 7000-ft2 monolithic concrete slab foundation with 7 different levels. I was there as it was being poured and I never thought to watch what they did with the level changes. However, clearly it can be done, or does it require very specialized concrete people not commonly found outside of south Houston where this house is located?
