Las Vegas Concrete Scanning Projects that Penhall Worked On

Inspect concrete before redesigning

A construction company hired Penhall Technologies for digital concrete x-ray and concrete scanning. The location was at an 11-story building casino that needed major redesigning and was proposed to go up 68 stories. Our x-ray technicians used the Comet Evo-300D and Novo detector panel to inspect and image the concrete. This project was then followed by ground penetrating radar, using the GSSI Mini. We found PVC conduit, metal pipes, PT cables, and rebar in the concrete.

Locate post tension cable before construction

Recently, our analysts have been working at a resort in Las Vegas, Nevada. This project requires both digital concrete x-ray and concrete scanning. The main purpose of the scan is to locate post tension cables before construction. In highly congested areas digital x-ray has been used to confirm layers of PT cable or rebar. Our team of analyst have found metal pipes, PT cable, and rebar.

Core safely by performing concrete scanning and digital concrete x-ray

Penhall Technologies was hired to perform digital concrete x-ray and concrete scanning at a resort in Las Vegas, NV. The client wanted to scan before core drilling in a vertical wall, which will be used to anchor a crane for safe operation. He also wanted X-Ray images to know exactly what is in each slab. The analyst used the GSSI Mini HR and NOVO Digital Radiography machine to inspect the concrete. Then, he marked out areas for the crane anchors and to show exactly what was in each slab.

GPR scanning used to determine rebar patterns

determine rebar patterns with gpr concrete scanningPenhall Technologies was recently hired for a project in Las Vegas, NV. The job consisted of GPR concrete scanning services on 13 locations in preparation to core drilling. The client informed the analyst that the concrete slabs that were scanned were all 6″ thick and needed cores ranging in size between 1″ – 2 1/2″ in diameter. With this information in mind, the analyst completed the scanning. The objects found were marked accordingly. This gave the client an approximate location to safely drill the cores into the examined concrete slab.

Scanning concrete wall to find post tension cable and existing conduit

scanning concrete wall to find post tension cable and conduitPenhall Technologies was called to perform concrete scanning services at a location in Las Vegas, NV. Our analysts used ground penetrating radar (GPR) to inspect three locations on a 6″ thick pan decked tilt-up wall. The client wanted to confirm if any obstructions, such as post tension cables or rebar, were present in the slab prior to drilling 4″ diameter cores. The analyst marked any post tension cable and rebar found in the concrete slab, so the client had a safe area to perform his job and complete his project on time.

Analyst completes GPR scan in department store

Penhall Technologies was contracted so scan for a trench cut 2’x75’ inside a department store at a mall in Las Vegas. This job had to be completed after hours as the store was operating during normal business hours. Penhall Technologies scanned a 3’x80’ area for the trench. A 4’x79’ area would have been ideal but we were limited by a wall running the length of the trench. All rebar and subsurface hazards were located and marked in either black for rebar, or red for post tension cables or hazards. All finds were clearly marked and clear coated for customer.
