Aggregates

Our lab is CCIL certified for Types C and D and is fully equipped to carry out Low and High complexity testing

About the Service

Construction aggregates come in various sizes, shapes, and types, depending on their intended use. They can range from fine sand particles to large rocks, and different types of rocks, such as limestone, granite, or basalt, can be used as aggregates. The choice of aggregates depends on factors like project requirements, availability, and engineering specifications.

Aggregates used in construction projects must meet strict regulations and quality standards. As these standards are often compulsory, aggregate testing by an independent third-party laboratory is necessary to help assure compliance. Our in-house aggregate and soil testing laboratory has been proficient in providing precise and valid test results over the years.

PNJ Engineering also participates in the Ministry of Transportation’s annual aggregate and soil proficiency programs. Our participation in laboratory certifications and annual proficiency programs, provide a higher confidence in testing results for your construction projects.

Our lab is CCIL certified for Types C and D and is fully equipped to carry out Low and High complexity testing for granular, asphalt and concrete aggregates.
