Overview
Half cell potential measurement is used to evaluate the potential for corrosion, and subsequently, the durability of concrete reinforcement. It provides a standardised outcome and can deliver fast results.
Benefits
Applications of Half Cell Potential
The test is cost-effective and can be used in any concrete structure where a connection point to the rebar network is possible. The survey is described in the ASTM C876 standard and can be carried out alongside Xradar™ Corrosion Mapping to cross reference corrosion results.
HCP is most suitable for concrete structures such as parking lots, concrete piers, docks and tunnels.
Technology
Half cell potential works by measuring the potential difference between a reference electrode placed on the surface of the concrete and the rebar network within the structure beneath.
Measurements are done in a grid pattern, and subsequent data points are gridded to provide a contour map of the half cell potential gradient values throughout the survey area.

XRSounder geomaps delamination live to a CAD-exportable file. The device includes XRMapper post-processing software, allowing engineers and inspectors to digitally map large areas, overlay data, and historically track condition assessments over time.
-
It is built for large concrete structures, including parking garages (parkades), bridge decks, warehouse and industrial floors, and municipal infrastructure.
-
Yes. XRSounder effectively locates and maps areas where protective coatings or membranes have lost adhesion, helping to prevent costly water ingress and surface failure that traditional sounding might miss.
-
The system offers high-resolution, pinpoint detection capable of resolving concrete defects and delamination down to one square foot. This accuracy enables early intervention and helps prevent costly, widespread repairs.

The Importance of Hiring a Concrete Scanning Service
Concrete scanning technology has transformed the way contractors, engineers, and building owners understand what lies inside concrete structures. Whether you’re coring, cutting, drilling, renovating, or conducting structural investigations, Ground Penetrating Radar (GPR) scanning has become the preferred method for identifying embedded objects before work begins.

Introducing GRAD: Unlocking the Full Value of GPR Data
Ground Penetrating Radar technology has transformed the way we investigate concrete and subsurface conditions. Modern GPR systems can collect enormous amounts of high-resolution data, providing valuable insights into structural elements, embedded objects, and hidden conditions. However, the true value of that data depends on how effectively it can be processed, interpreted, and communicated.
