Locate conduit with concrete scanning

Recently, Penhall Technologies was hired to locate embedments in preparation of bollard placement on the top level of a parking structure. This was part of an ongoing project to update our client’s wireless communications. Our analyst used the Hilti PS1000 and performed sweeps with the RD7100 to confirm there was no live conduit present. She located conduit, PT cable, and rebar.

Scan for pan decking with GPR

A construction company contacted us to mark pan decking in highs and lows and also mark any rebar or conduit that was in the slab. Our client had contacted other companies that told him that they wouldn’t be able to scan the pan decking. Our expert analyst took on the challenge and found and marked out pan decking with ease, using the GSSI Mini. Additionally, he performed sweeps with the RD7100 to locate any live conduit. Our analyst also found wire mesh in the slab. The customer was thrilled that we were able to come through when other companies couldn’t.

Use concrete scanning to find obstructions, such as rebar, tension cables, or conduit

Scanning to find obstructions, such as rebar, post tension cable, or conduitIn Greenville, Penhall Technologies was requested for our concrete scanning services. Our analyst scanned three separate areas on 8″ thick concrete slab for any obstructions, such as rebar, post tension cable, or conduit. After scanning, Penhall’s operators were now safe to perform core drilling of 4″ diameter holes.

Avoid hitting post tension cables before drilling into a post tension slab

avoid hitting tension cables when drilling into post tension slabPenhall Technologies scanned a condo unit to locate post tension cables at multiple locations prior to drilling into the ceiling. The building engineer was concerned that the post tension cables would be damaged during renovation. The analyst was able to scan and mark out the location of the cables using ground penetrating radar. During the concrete scanning, the analyst also noted several conduits in the concrete slab. By marking out all the hazards, the customer could drill without damaging any post tension cables and incurring repair costs.
