Concrete Floor Slab Thickness

This is largely based on the types and the number of vehicles you plan to park on it.

Concrete floor slab thickness.

Design process includes proper assumption of structural element sizes and then check. It needs to be thicker if heavy equipment will rest on it. 4 inches 0 1 m. The thickness of concrete is an important factor in load bearing strength but to conserve resources and avoid over building other factors are also taken into consideration.

Minimum thickness of concrete structural elements based on aci 318 14 irc 2009 is 456 2000 and ubc 1997 is presented. For slabs drying from one side the depth is 40 of the thickness. Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes. 4 5 inches 0 1 0 125 m farm building floors home basement floors.

For that reason knowing the thickness of the concrete slab is critical. This test is called the relative humidity test using in situ probes and it s the basis for the astm f2170 standard. 6 8 inches 0 15 0 2 m side walks barn and granny floors. The standards are expressed in terms of compressive strength which boils down to the amount of water used in the mix.

Click the button to calculate the volume of concrete and man hours not including mixing needed for this job. Type of use how thick you pour your concrete floor can be determined by how the floor is going to be used.

The standard concrete garage floor is six inches thick and with use of proper control joints should be thick enough to withstand normal use. Structural concrete work is planned to bear loads or hold weight but transfer the weight to the soil base beneath the structure. 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. 5 6 inches 0 125 0 15 m porches home garage floors.

Thickness of garage floor slab. Common mistakes in concrete floor slab construction can be avoided with proper base preparation mix design placement finishing and curing.
