Hello; In the attached project, there is a landscape area in front of the villas. I determined the rib flooring thickness as 40cm due to the soil load (60cm). It saves 35 cm as well, but after the application, I was afraid that different loadings could be done and I made 40 cm. There will be a joint after the F axis and the 2nd part will be the same. I'm curious about your thoughts and suggestions in general. good work everyone.
