Externet Posted January 25, 2013 Share Posted January 25, 2013 Hi. Did not pay enough attention when a 10,000 sq.ft. freezer was added at a facility I worked at many years ago. ...Remember a reinforced concrete slab poured on the ground, then a ~8" layer of styrofoam, and another reinforced concrete slab on top. Forklifts danced all over that floor with no problem. Am I missing details?; what is the building technique to avoid cracking/collapse with such styrofoam sandwich ? How is it done properly int the civil engineering world ? Link to comment Share on other sites More sharing options...
michel123456 Posted January 25, 2013 Share Posted January 25, 2013 (edited) After some googling for the translation of french "chape flottante" I found "floating screed" usually the concrete floor floating upon the styrofoam is reinforced (as you said) so that the loads are distributed over a large surface. ------------ Cracking/collapsing may happen near the expansion joints. Otherwise styrofoam works well. Moving loads are not that much. Edited January 25, 2013 by michel123456 2 Link to comment Share on other sites More sharing options...
