Concrete

Our lab is CCIL certified for Concrete Types Q, R, and S, offering services in concrete materials.

About the Service

PNJ’s expertise on field and laboratory evaluation of concrete materialis vast. Our extensive experience in performing qualitative assessment andproviding an understanding with regards to the interpretation of the results,coincides with our in house laboratory to provide precise and valid testresults.

PNJ Engineering also participates in the Ministry of Transportation’sannual compressive strength, rapid chloride permeability (RCP),admixture andcuring compound proficiency programs. Our participation in laboratorycertifications and annual proficiency programs, provide a higher confidence intesting results for your construction project.
