Test Packages

A PTS Laboratories Test Package combines several basic analyses and/or index properties to provide an integrated data package. We can also create custom packages that satisfy all modeling and risk assessment parameters or meet regulatory agency requirements.

Geotechnical and Construction Related Soil Tests

Our geotechnical and construction related testing capabilities round out the Physical Properties and Index Parameters category. Many analyses require undisturbed samples of 2” or 2-1/2" diameter or greater. Bulk or grab samples may suffice for other tests. PTS can work with core diameters of 1” diameter or less in many instances. Contact your PTS Laboratories customer service representative for more information and a testing fee summary.
