Slab thickness testing
Slab thickness testing
(OP)
Does anyone know of a way to have slab thickness verified without coring through the slab? If so, are there any companies in particular who might specialize in this operation?
Thanks,
Nick

Many years ago a company I worked for tried to establish floor thickness using both GPR and ultrasonic tests with no particular success. I would expect that the technique has advanced since then.
Even if you do get a good result it may be necessary to drill the slab to calibrate the results.
Out of interest why can't you core the floor?

How accurate do you need to be? The more accurate your requirement, the more likely you are to result to coring or drilling.
http://www.iti.northwestern.edu/pubs/landis.html is one website explaining some possible techniques

Thickness will depend on how level was the slab base was prepared. It is my opinion that variations in slab thickness that range from 1/4 to 1/2 inch are normal for slabs on grade.
