When concrete scanning CSI uses ground penetrating radar, which is an accepted and routinely used nondestructive method for imaging objects in concrete prior to cutting or coring. It is a safe application of radar regulated by the FCC and fieldwork typically requires only one operator. Imaging results are generated on-site for immediate mark out and analysis of targets in selected areas. The inspection, under normal circumstances, can be performed from one side of the wall or slab, which also permits slab-on-grade scanning.
Some applications of GPR include, but are not limited to:
· Locating reinforcing bars
· Locating post-tension cables
· Locating metallic and non-metallic conduits
· Detecting voids beneath slab-on-grade
· Determining slab thickness and cover depth to targets
Damaging structural elements such as conduit, rebar, and post tension cable can be dangerous and costly; let us keep your projects on time, reduce safety risks, and decrease potential structural issues.
Be Wise - Scan Before You Cut or Core
Private Utility Locating is the process of identifying and labeling underground utility mains. These mains may include:
· Electricity Distribution
· Natural Gas
· Cable Television
· Fiber Optics
· Traffic Lights
· Street Lights
· Storm Drains
· Water Mains
· Wastewater Pipes
· Oil/Gas Pipelines
· Mass Transit
When locating utilities Concrete Scanning and Imaging, Inc. uses a Electromagnetic Detection, Ground Penetrating Radar, or a combination of both. Mark outs can be don with flags and/or spray paint depending on the area, surface, and customer preference.
CSI does not replace 811. We supplement their search, identifying depth of target and utilities beyond the meter.
CSI's Methods for Locating Utilities Underground
· Electromagnetic Utility Locating: This is the most common technique used for utility locating. This process consists of a transmitter and a receiver. The transmitter applies a high frequency current to the utility line and the receiver detects it. This method is very accurate and is most commonly used to locate electric, gas, telephone, cable, sewer, water, storm, irrigation, and propane lines. Electromagnetic Utility Locating is an accurate method that does have some limitations including; unmarked plastic, asbestos, concrete, tera-cotta, and non-ductile pipes.
· Ground Penetrating Radar: GPR, like electromagnetic locating, uses high frequency pulses to locate buried objects. The frequency is projected into the ground and objects that are buried reflect the signal back to the operator for an instantaneous reading. This method is most commonly used when locating non-metallic objects buried beneath the surface. Using Ground Penetrating Radar requires extensive training and experience to read the results. CSI’s techs will walk you through the results to make sure you understand the results before you cut, core, or dig.
CCTV Pipe Inspection is a method of evaluating subsurface utility lines using HD cameras and sewer inspection systems to investigate the interior of buried drain and sewer lines. CCTV Pipe Inspection provides real time HD camera footage for pipes from 6" - 96" inches in diameter.
CCTV Pipe Inspection can determine:
CSI's antennas can penetrate up to 18″ thick concrete from one side and up to 36" if accessible from both sides.
Extremely accurate! On an average slab on grade inspection, targets were located +/- 1/4″ of their markings laterally and +/- 1/4″ of their depth estimations.
In most cases, CSI can have a technician on site in 24 hours or less.
