Service overview

A thermal testing laboratory for your project materials

If a specification calls for a thermal test, rho value, or conductivity report, start with the material and the requirement. We help translate that request into a defined laboratory scope: what to send, which condition to test, and what data the project reviewer needs.

Our work focuses on heat transfer through soil and cementitious construction materials surrounding underground power systems. These thermal testing services support duct-bank concrete submittals, native-soil evaluation, imported backfill selection, and production material verification.

Calicore Engineering and Soil Tests Laboratory are part of the same business. Nolan Ferguson, PE, leads the practice, connecting the laboratory request with the engineering purpose of the test. Samples can be submitted from projects throughout the United States after intake instructions are confirmed.

Find the thermal testing service that fits

Electrical and geotechnical engineers commonly request thermal resistivity, also called thermal rho. Other specifications call for thermal conductivity. Ready-mix and precast producers may need a concrete rho test to support a mix submittal. Tell us how the result will be used so the report addresses the correct property, units, and specimen condition.

Why work with Calicore for thermal testing?

A useful laboratory report connects a result to the material that produced it. We establish the sample identification, preparation, requested moisture or density condition, and reporting requirements before testing. A dry-out program includes the measured points and curve so the receiving engineer can review the material’s response as it dries.

You can discuss the project with an engineer, submit samples nationwide, and coordinate related soil testing where it is part of the scope. Confirm specimen needs and turnaround in business days before shipping; concrete curing and specimen conditioning need to be included in the schedule.

Step by step

How the process works

The exact scope is matched to the project, but a typical assignment follows these steps.

  1. 01

    Share the requirement

    Send the specification, drawing note, or email requesting thermal testing, along with the material and project deadline.

  2. 02

    Confirm the scope and quote

    Agree on the property, units, specimen preparation, single-point or curve program, sample count, and schedule.

  3. 03

    Submit identified samples

    Follow the confirmed collection and packaging instructions and include a record of the source, mix, or sampling location.

  4. 04

    Receive the thermal report

    The results are issued with the specimen conditions and agreed deliverables for the receiving engineer or material reviewer.

Frequently asked

Thermal Testing Company for Soil, Concrete & Backfill questions

What does your thermal testing company test?+

Calicore and Soil Tests Laboratory test soil, sand, concrete, grout, flowable fill, and suitable backfill materials for thermal resistivity and conductivity. Send the material description and specification so we can confirm suitability and sample requirements.

Do I need a local thermal testing lab?+

For laboratory testing, samples can be shipped from across the United States. If the project requires in-place soil measurements, Calicore can separately scope an in-situ thermal survey and any associated sample collection.

Which standards should I request?+

ASTM D5334 and IEEE 442 are common references for this work. Send the specified edition, acceptance condition, units, and required deliverable so the laboratory can confirm the appropriate program.

Can you help if my request only says thermal testing?+

Yes. Send the drawing note, specification, or email that requested the test. We will clarify whether you need material conductivity, thermal rho, a dry-out curve, or a different service before samples are prepared.

Is this the same as thermal imaging or thermal shock testing?+

No. This service measures heat-transfer properties of soil and construction materials. Thermal imaging, environmental chamber testing, and thermal shock testing answer different questions and are not included in this offering.

How do I request pricing and turnaround?+

Provide the material, sample count, test requirement, specimen readiness, project location, and report deadline. The quote confirms the test scope and turnaround in business days, with curing, shipping, or additional preparation identified separately as applicable.
