Detect Reinforcing & Utilities Embedded Within Concrete Structures

Our concrete imaging and scanning services can help you determine the location and depth of the following six objects commonly embedded within concrete structures:

Rebar

Mesh

Post-Tension Cables

Pre-Tension Cables

Conduits

Pipes

Detect Voids & Map Deteriorating Areas of Concrete

Our concrete imaging and scanning services can also help you inspect older concrete structures to obtain the following information:

The Location of Voids

Areas of Deteriorating Concrete

Inspect Newly Built Concrete Structures

Our more advanced inspection services can help you determine if newly built concrete structures conform to the information shown on their as-builts:

Location of Rebar According to the Asbuilt

Location of Rebar According to GPR Data

Plan Showing Location of Rebar After GPR Survey

Cross Section View of Vertical Rebar

Actual Location of Rebar in the Field

The Actual Location of Vertical Rebar in the Field After Chipping

Concrete Structures Capable of Being Scanned

We are capable of scanning the following six different types of concrete structures:

Suspended Slabs

Slabs-on-Grade

Columns

Beams

Tilt Walls

CMU Walls

Scanning Concrete With Ground Penetrating Radar (GPR) Technology

Our concrete imaging and scanning surveys are performed with ground penetrating radar (GPR) technology using a customized eight-step concrete imaging and scanning process. GPR technology enables our technicians to scan concrete structures in real-time using a small hand cart, providing immediate results right in the field. Unlike radiography (x-ray) the GPR signal is harmless, a permit is not required, and an exclusion zone is not necessary. Below is an example of some GPR data and the transcription of this data to the surface of a post-tension concrete slab.

Four Concrete Imaging & Scanning Survey Design Options

In order to handle a wide variety of different types of projects, we offer our clients four different survey design options. Feel free to choose the option that best fits your needs. If you are not sure which one that is, we can recommend one for you after learning more about your project.

Single Location

When drilling, coring, or cutting through the slab at a single location, such as for running a new conduit or pipe through the slab, we can scan a 3' x 3' area surrounding this one location.

Clustered Locations

Multiple Core Locations in One Survey Grid

When multiple drilling, coring, or cutting locations are situated close enough to one another within the same section of the slab, we can scan one large area encompassing all of these locations.

Partial Structure

Partial Section of Large Concrete Structure

When the exact drilling or coring locations or cutting areas are unknown and the structure is large, we can scan a specific section of it, enabling our clients to position their locations accordingly. This same design option is also useful when doing a concrete inspection of an extremely large concrete structure.

Full Structure

When an entire structure needs to be imaged because the exact drilling or coring locations or cutting areas are unknown, or the entire reinforcing layout needs to be determined for concrete inspection purposes, we can scan the entire structure. But this is usually very costly and time consuming, so we avoid it at all costs.

Two Levels of Concrete Imaging & Scanning Service

In addition to offering four different survey design options, we also offer two different levels of service. Feel free to choose the level of service that best fits your needs. If you are not sure which one that is, we can recommend one for you.

Level 1 - Field Markings

This is our least complex, quickest, and cheapest level of service. A concrete imaging survey is performed; the results of the survey are marked on the surface with chalk, paint, marker, tape, crayon, or wax pencil; and a consultation is then performed with an on-site representative to discuss the results of the survey.

Level 2 - Field Markings & Written Report

This is our most complex, time consuming, and expensive level of service. A concrete imaging survey is performed; the results of the survey are marked on the surface with chalk, paint, marker, tape, crayon, or wax pencil; a consultation is performed with an on-site representative to discuss the results of the survey; and a written concrete imaging report (PDF), explaining and documenting the results of the survey, is sent via email or a Google Drive shared link.
