Biloxi Concrete Scanning Projects that Penhall Worked On

Scan concrete flooring to locate rebar, tension cables, and conduit

concrete floor scanning to find rebar, cables, or conduitPenhall scanned for a sporting goods store in Biloxi.  Our analyst used ground penetrating radar to locate and mark any obstructions in the concrete flooring such as rebar, post-tension cable, or conduit.

Locate conduit in concrete using GPR

Find and mark conduit in concrete using GPRPenhall was asked to come out and perform GPR scanning at a shopping center in Gulfport, MS.  We were asked to scan one area of approximately 3’ x 10’ to locate and mark the conduit within the concrete in preparation to cutting and removing two slab openings.

Ground penetrating radar used on scaffolding before core drilling for installing electrical

Penhall was pleased when asked to scan for NASA’s Stennis Space Center. We used ground penetrating radar to scan 2 areas of 1′ x 3′ on scaffolding prior to core drilling eight 6″ holes. This was all done prior to installing some electrical conduit for the building.

Concrete scanning on post tension slab to locate cables and rebar

gpr scanning to locate rebar and post tension cableAt a hotel and casino in Biloxi, Penhall was asked to perform some concrete scanning and core drilling on four areas on two floors.  It was necessary to scan first to ensure that there were no obstructions when core drilling 9” holes at 9” deep.
