PCTS carry out Electrical Resistivity Testing using the Wenner Four Point Probe to assess the quality / uniformity of concrete at various depths.

Introduction

PCTS electrical resistivity testing using proseq ResiElectrical current is passed through the outer probes and potential drop is measured by the inner probes. From the current and voltage drop measurements, the resistivity of the concrete is measured. PCTS are able to relate this resistivity to the quality of the concrete.
