Charleston Concrete Scanning Projects that Penhall Worked On

Penhall locates all electrical conduits, so conduits are not hit during core drilling

concrete scanning to locate electrical conduits in slabRecently, a local construction company hired Penhall Technologies to scan the floor of a waste water treatment facility located in Charleston, SC. The construction company wanted to know the location of all the electrical conduit in the floor of four locations in question. The construction company needed to core drill a large number of holes into the floor and they wanted to avoid striking these conduits. We scanned the four areas around the facility and located several conduits. We used the GSSI Structure Scan Mini HR to scan the areas and followed up by performing sweeps with our radio detection device (RD 7100), which will pick up any live power or communication lines. Penhall Technologies was able to exceed the expectations of the client by not only locating the conduit and rebar, but marking them out on the surface in real time using a specific color code utilized by the company. The project was completed in a safe and non-destructive manner. Penhall Technologies of South Carolina has the capability and the man power to meet your needs in a timely manner, ultimately ensuring your projects get finished safely and on time.

Concrete scanning provides 2D profiles and 3D volumes to determine the integrity of walls

concrete scanning to determine the integrity of building wallsA local contracting company hired Penhall Technologies to scan and map a concrete wall inside a hospital in Charleston, SC. The hiring company was interested in knowing how much structural rebar was in the concrete wall and in what direction the rebar was going. The contracting company is interested in building an addition to the one story building and the project engineer wanted to know if the wall was originally engineered to support the added load of a second story. Penhall Technologies scanned the wall with the Structure Scan Mini HR from Geophysical Survey Systems Inc. (GSSI) collecting both 2D profiles as well as two 3D volumes. The 2D profiles were used to map the rebar at the surface while the 3D volumes were used to map out the rebar to deliver to the structural engineer. Penhall Technologies was able to exceed the expectations of the client by not only locating the rebar, but marking them out on the surface in real time and providing limited technical support viewing the delivered 3D volume. The project was completed in a safe and non-destructive manner.

Determine if there are any obstructions with concrete using GPR scanning

locating obstruction in concrete using GPR scanning This project called for Penhall to travel to Moncks Corner, SC. Once there, we were instructed to perform concrete scanning for obstructions in several areas before drilling for 12” cores on the 8” slab.

Locate and mark rebar and post tension cable to ensure safety when core drilling

locate and mark rebar and post tension cable in concrete slabPenhall was contacted to perform concrete scanning on 150 separate areas at a central location in Charleston, SC. We used ground penetrating radar to locate rebar in preparation for the core drilling on the 5” thick slab.
