Materials Testing Services

Before you build, you need to have confidence in the site and the quality of the materials. PRI Engineering’s comprehensive materials testing and inspection services help our clients manage risk to meet project specifications, construction standards, timelines, and available budget.

Our certified technicians and engineers draw upon decades of on-site and technical experience in local areas to support the success of your project. PRI Engineering evaluates and determines the quality of the materials in the field or in our CCIL-certified laboratory through sampling and testing your soil, aggregate, rocks, asphalt, and concrete. You gain deeper insight into the composition and performance of your materials in accordance with published standards or site-specific requirements.

  • On-site material collection of soil, aggregate, and concrete for quality control/assurance purposes
  • On-site compaction testing
  • Laboratory material testing
  • Independent third-party inspection

Geotechnical Field Testing and Analysis

PRI Engineering applies the best practices in geotechnical field testing to design a program specific to your site and construction. Our local experience partnered with over 100 years of combined engineering experience allows us to identify the design and testing constraints to optimize your on-site testing program.

Soils Field Testing

  • In-situ compaction testing using nuclear densometer methods
  • Dynamic probe testing to determine relative density of non-cohesive materials and consistency of cohesive materials

Rock Field Testing

  • Review of bedrock materials per the ISRM classification system to determine engineering properties
  • Tests include: point load test, deformability testing, in-situ stress test, water content tests, density tests, porosity tests, and water pressure test for permeability

Concrete Field Testing

  • Air testing of concrete
  • Slump testing of fresh concrete
  • Temperature testing of fresh concrete
  • Casting cylindrical specimens for laboratory testing

Asphalt Field Testing

  • Nuclear field density determination
  • Asphalt coring and core sampling

Geotechnical Laboratory Testing

PRI Engineering’s comprehensive geotechnical laboratory testing evaluates the performance and composition of your materials to meet quality standards. Our CCIL-certified laboratory tests soils, concrete, and aggregate for particle size, moisture content, particle shape, and more. This geotechnical laboratory testing helps you determine the condition of your construction site and building materials so that you can build a safe and lasting structure based on PRI Engineering’s recommendations.

Soils Laboratory Testing

  • Natural Moisture Content of Soils
  • Particle Size Analysis utilizing Sieve and Hydrometer methods
  • Atterberg Limits Test for determining liquid limit and plasticity testing
  • Determination of the standard or modified Proctor maximum dry density (SPMDD or MPMDD)

Concrete Laboratory Testing

  • Compression testing

Soil and Asphalt Compaction Testing

Geotechnical compaction testing, including soil and asphalt compaction testing, helps ensure you build your roads, parking lots, and other construction projects on a solid foundation. PRI Engineering uses advanced equipment, such as nuclear densometers, to determine your material’s compaction on-site. We return core samples to our state-of-the-art laboratory for more comprehensive geotechnical compaction testing.

Soils Compaction Testing

  • In-situ compaction testing using nuclear densometer methods
  • Dynamic probe testing to determine relative density of non-cohesive materials and consistency of cohesive materials

Asphalt Compaction Testing

  • In-situ compaction testing using nuclear densometer methods
  • Asphalt core sampling for subsequent lab testing

Common Questions

Many companies have questions about material testing and its benefits. We answer some common material testing questions below, and if you have any more questions, contact us. We are happy to help you learn how material testing can help your next project.

What is material testing in engineering?

Material testing for civil engineering involves testing materials such as soil, concrete, and aggregate for public works projects such as roadways and other construction projects. This material testing helps civil engineers gain a better understanding of site materials and building materials. They can then make decisions based on this information, such as adjusting building materials to suit the project’s needs or adjusting the project to complement site properties. Without this material testing, civil engineers would be missing critical information they need to make their recommendations.

What is material testing in construction?

Companies request material testing before, during, and after construction. Testing materials such as soil, concrete, and aggregate helps ensure construction companies are aware of the properties of their raw materials. They can then adjust the materials, or their plans, accordingly. It also helps ensure construction companies build with appropriate materials, such as concrete with the desired strength, and it helps ensure the finished product is safe. When companies request material testing for construction, they become more aware of what they are building on and building with.

How long is a geotechnical report valid?

Often, a geotechnical report can remain valid for decades, assuming a trustworthy and reputable materials testing company, such as PRI Engineering, prepares the report. The geotechnical report may become invalid if the site experiences any significant changes, such as natural disturbances, the addition of fill, or major construction. The geotechnical report’s recommendations may also become invalid when code, building standards, or the project scope change. Of course, when in doubt, the safest choice is to prepare a new geotechnical report.
