Ship samples
Local project teams collect traceable material and send it to Calicore’s laboratory after quantity, packaging, preservation, and preparation are confirmed.
260 regional and city project guides
Thermal resistivity testing across the United States
Ship representative soil, backfill, concrete, grout, or slurry samples from any U.S. project. Calicore also performs project-based in-situ thermal surveys when the route, schedule, and engineering need justify a field mobilization.
Test controlled conditions
Order an as-received point, a specimen molded to a target density and moisture, a concrete or FTB program, or a full thermal dry-out curve.
Request a field survey
For selected projects, Calicore visits the site, establishes test points, measures suitable in-place material, documents conditions, and can collect lab samples.
Why regional pages?
Climate and geology guide the questions—not the answer.
Major U.S. metros differ in precipitation patterns, seasonal drying, freezing, groundwater setting, surficial geology, urban fill history, construction practices, and infrastructure demand. Those differences help a project team decide where samples or field points may be needed.
They do not justify a published “typical rho” for an entire city. Thermal resistivity changes with the actual material, density, moisture, structure, temperature, and preparation. Every regional page therefore explains local planning context while directing the design team back to project-specific measurements.

Each guide explains likely project applications, the shipped-sample process, how an in-situ survey works, what to send before sampling, and why a citywide thermal value should not be assumed.

Questions before you ship
Can Calicore test samples from any U.S. state?+
Yes. Soil and suitable material specimens can be shipped from U.S. projects after Calicore confirms the required quantity, packaging, sample condition, preparation, and schedule.
Can Calicore visit a site outside California?+
Yes. In-situ thermal surveys are available nationwide for appropriately scoped projects. Mobilization, access, excavation, utility clearance, and sample collection responsibilities are established in the proposal.
Do the metro pages give a local design rho?+
No. Regional soil and climate descriptions are planning context. A defensible project value must be tied to the actual material, location, moisture, density, preparation, and design method.
Can field testing and laboratory curves be combined?+
Yes. A field program can document current in-place points and collect representative material for controlled laboratory preparation and moisture-dependent dry-out curves.
Start with the design question
Send us the specification before you collect the sample.
Calicore will confirm the material, quantity, labels, preservation, density and moisture condition, specimen form, requested outputs, and shipping plan.
