Quality floor construction includes good subgrade compaction even thickness slabs low slump concrete straight bulkhead lines and control cuts spaced 24 to 30 times the slab thickness. For slabs drying from two sides the depth is 20 of the thickness. 4 inches 0 1 m.

This test is called the relative humidity test using in situ probes and it s the basis for the astm f2170 standard. Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes. The standard concrete garage floor is six inches thick and with use of proper control joints should be thick enough to withstand normal use. For slabs drying from one side the depth is 40 of the thickness.
