Establish Location and Depth of Post Tension Cables

Determine post tension (P.T.) cable draping characteristics through accurate 2D depth imaging with the StructureScan Optical. Avoid costly repairs and potentially dangerous events by locating post tension cables prior to cutting or coring work.

Determine the Thickness of a Concrete Slab

Contractors and engineers alike use StructureScan Optical to determine the thickness of suspended or on-grade concrete slabs.


Simple to Use – Get 3D Results in Minutes

1. Set Optical Smart Pad on concrete surface
2. Collect data with the Optical antenna
3. View and interpret data results
StructureScan 1600 MHz – General Purpose
With a depth range up to 18 inches (0.5 m), the 1600 MHz system offers a great balance between data resolution and depth penetration in concrete.
StructureScan 2600 MHz – High Resolution
With a depth range up to 12 inches (0.4 m), the 2600 MHz system offers the highest frequency GPR antenna in the industry. The higher resolution provides clear, easy-to-interpret data images and makes complicated job sites less obscure.

Concrete Inspection Antenna Solutions

2600 MHz: High-Resolution Antenna
The 2600 MHz is an ultra-high resolution antenna used to inspect concrete structures to locate embedded rebar, post tension cables and conduits. Depth Range: to 12 in (0.4 m)
1600 MHz: General Purpose Antenna
The 1600 MHz is a high-resolution, all-purpose antenna used to inspect concrete structures to locate embedded rebar, post tension cables and conduits. It is used on bridge decks for condition assessment and to determine concrete cover. Depth Range: to 18 in (0.5 m)
1000 MHz: Deep Penetration Antenna
The 1000 MHz antenna represents the state-of-the-art in shallow earth or deeper concrete imaging. This antenna is appropriate in areas where higher frequencies do not provide adequate penetration and lower frequencies do not provide acceptable resolution. Depth Range: to 24 in (0.6 m)

2000 MHz: Palm Antenna

The new Palm Antenna offers users the ability to reach tightly spaced areas that were previously inaccessible such as corners, against walls and around obstructions.

The Palm Antenna is compatible with the SIR-3000 and SIR-20 control units. The antenna includes a dedicated survey wheel, a replaceable skid plate, and removable handle to reduce antenna height, if necessary. The Palm Antenna weighs in at approximately one pound. Depth Range: to 12 in (0.4 m)
