Soil Testing & Thermal Resistivity
Percolation Testing & Septic Design
Percolation tests measure how quickly water drains into soil at the tested location and depth. Results support septic-system and drainage planning, subject to local requirements. We provide percolation testing and septic design services in California and Nevada. Send your project location and jurisdiction requirements for a quote.
Our Services
Thermal Resistivity & Conductivity Testing
Our thermal testing laboratory measures soil, concrete and backfill for buried power cable and duct-bank projects. Thermal resistivity testing includes single-point measurements and dry-out curves, using ASTM D5334 methods and IEEE 442 guidance. Soil molding is included free of charge.
Explore concrete rho testing for ready-mix producers and flowable fill, CLSM and FTB testing. Contact us to confirm sample preparation and testing scope.
Soil Corrosivity Testing & Recommendation Reports
Detailed analysis and recommendations from our expert Corrosion Engineer. Soil samples can be collected by our collection team or your local geotechnical firm. Reports provide recommendations for material selection and corrosion rates in all forms of corrosive environments.
Wenner 4-pin Testing (In-Situ Resistivity Testing)
Our Engineers provide in-situ soil resistivity via Wenner 4 pin (4 electrode) method ASTM G57. All equipment is compliant with IEEE 81. Testing is performed by qualified engineers. Contact us directly for pricing.

Packages and Pricing
Percolation Testing
Perc testing includes a full report stamped by a registered Professional Engineer, ready for submittal to your local jurisdiction. The price varies depending upon the county requirements and site conditions. We guarantee the lowest price for a PE stamped report. If you found someone cheaper we will not only match the price but we will beat it.
Soil Corrosivity Evaluations
Caltrans Corrosivity Test Package - $125/sample (Tests for Resistivity, pH, Sulphates and Chlorides)
Full Corrosion Test Package - $150/sample (Tests for Resistivity, pH, Sulphates, Chlorides, Ammonia, Nitrates, Redox and Sulfides)
Corrosion Control Recommendation Report - $1000+$100/Sample (3 Sample Minimum)
Thermal Resistivity Dry Out Curves
$625/Sample
Thermal resistivity dry-out curves, as per ASTM D5334 & IEEE 442, illustrate how soil or concrete’s thermal resistivity changes as moisture content decreases. These curves are essential for understanding soil behavior under varying moisture conditions, aiding in the design of thermal management systems for underground installations..
