Cover meter for locating plate dowels?
Cover meter for locating plate dowels?
(OP)
Hi everyone. First time poster.
I've been looking for a cover meter or similar hand-held NDT device to locate dowels in concrete slabs on grade. The dowels are on saw-cut joints. The catch is that the dowels are usually plate dowels (as apposed to round dowels), and of the cover meters I have been able to try, they all do well on round dowels, but struggle to pick up plate dowels. They tend to pick up the small tie straps
Typically the dowels are around 75-100mm below the surface (ie mid way in a 150-200mm thick slab).
Does anyone have any experience with devices which can reliably locate plate dowels, or can anyone give any advice?
Cheers
Andrew

There is also the profoscope which is meant to be a good piece of equipment. http://www.profoscope.com/ A sales rep scanned the columns and slab in our building with good results (I had a set of structural drawings of the building).
I got a quote on the profoscope from a supplier of testing equipment (http://www.pcte.com.au/) for $4500AUD about a year ago now. I didn't purchase the product.

The zircon videoscanner is listed online for about $35 so I guess I have not much to loose by trying it out.
The concrete was quite young (2-3 days old i from memory). Can this affect the results? The rep had an x-ray scanning device with him which also didn't work. He seemed to think this was because of the high moisture content of the slab.
Ron, the Profometer is probably more expensive than we would like to pay. From memory it was 3-4 times more expensive than the profometer.
