Concrete Assessment

Thickness & Void Detection.

Gather non-destructive information about concrete thickness, subsurface interfaces and anomalous responses that may warrant further investigation.

Concrete Investigation

Understand More About What You're Working With.

Where conditions allow, GPR can help estimate concrete thickness and identify subsurface responses that differ from surrounding material. This information can support engineers, contractors and project teams during investigation, renovation and planning work without immediately resorting to destructive testing.

GPR provides interpreted subsurface information.

Thickness estimates and anomalous responses depend on concrete conditions, accessible scan surfaces and the presence of a distinguishable subsurface interface or material contrast.

What GPR Can Help Investigate

Estimated concrete slab thickness where a suitable back-surface response can be identified
Anomalous responses that may be consistent with voids or changes in subsurface conditions
Detectable changes between material layers or interfaces
Areas showing responses different from the surrounding concrete
Subsurface or base interfaces where scan conditions and material contrast permit interpretation

Common Applications

01

Slab Investigation

Gather thickness information about existing concrete where conditions allow.

02

Structural Assessment Support

Provide additional non-destructive information for engineering review.

03

Slab-on-Grade Review

Investigate thickness and detectable subsurface interfaces in accessible areas.

04

Anomaly Investigation

Identify areas showing responses different from surrounding material.

05

Renovation Planning

Gather more information about existing concrete before planned modifications.

06

Construction Investigation

Support review of selected concrete areas where additional information is needed.

Understanding Thickness & Void Results

Concrete thickness values obtained from GPR are estimates and may benefit from calibration against a known thickness or reference point. An anomalous GPR response is not, by itself, confirmation of a void, honeycombing or another specific defect. Confirmation may require additional investigation or engineering review.

The Process

From Investigation Area to Useful Concrete Information.

A practical workflow designed around the investigation objective, accessible surface and concrete conditions.

01

Review

We review the project objective, available information and accessible investigation area.

02

Scan

GPR data is collected systematically across the agreed concrete surface.

03

Interpret

Thickness responses, interfaces and anomalous areas are reviewed where distinguishable.

04

Deliver

Agreed scan information, identified areas and/or project documentation are provided.
