Concrete Slab Imaging (Structure Scan)

Concrete Slab Imaging (Structure Scan)

Safely locates embedments within concrete structures prior to drilling, cutting or coring up to a depth of 18 inches. With the high-resolution antennae, even small targets are located within minutes. Only single sided access is required to perform surveys, and a large area can be inspected in one day. The compact data acquisition system provides clear and reliable data, while remaining user-friendly at the same time.

Locates subsurface object and its depth on the job-site. The Structure Scan handcart is first rolled over the desired survey area (wall, floor or ceiling) and when an object is spotted on the data screen; we simply back up the hand cart and mark the target. Structure Scan provides immediate results when timing is crucial, with no need to close off work areas. Multiple antenna options (1.5 GHz and 900 MHz) also ensure that appropriate depth results are acquired.

 

Ground-penetrating radar as a three-dimensional mapping technique:

GPR produces three-dimensional images by creating pulses of radar energy at a surface antenna, transmitting those pulses into the ground and measuring the elapsed time between when they were sent, reflected off buried targets, and received back at a surface antenna. As the antenna is pulled over the ground surface, a two-dimensional vertical slice showing the significant reflections in the ground is obtained.   Approximate depth in the ground for each of the reflections can be determined when radar travel times are converted to depth.  When many transects are collected in a closely spaced grid, a three-dimensional cube of reflection data are available for processing and image production
