Our Services

Geotechnical Drilling

Tri Star Drilling & Testing provides geotechnical drilling and sampling services to support subsurface exploration and geotechnical design. Our drilling operations focus on obtaining representative soil and rock samples for laboratory testing and engineering evaluation.

Our crews work closely with geotechnical engineers and project teams to ensure borings are completed efficiently, logged accurately, and performed in accordance with project requirements and applicable standards.

Typical Drilling Services Include:

  • Soil borings with standard penetration testing
  • Shelby tube sampling
  • Auger and rotary drilling methods
  • Manual drilling techniques for confined or limited access areas
  • Non-destructive dynamic cone penetrometer readings
  • Coring capabilities through asphalt and concrete pavements
  • Coordination with geotechnical engineers during field operations

Our experienced team focuses on accurate data collection and safe drilling practices on projects ranging from small residential developments to large scale infrastructure work.

Geotechnical and Materials Laboratory Testing

Tri Star Drilling & Testing provides laboratory testing services that support soil classification, material evaluation, and construction quality assurance/control for geotechnical and construction projects. Our laboratory testing focuses on index properties, material characterization, and verification testing used during design support and construction.

Testing is performed in accordance with applicable ASTM and TxDOT standards, with an emphasis on clear reporting and practical use of results.

Laboratory Testing Services Include:

  • Soil Classification and Index Properties
    1. Moisture content testing
    2. Atterberg limits testing
    3. Particle size analysis and gradation
    4. Soil classification for geotechnical evaluation
  • Soil classification and grain size analysis
  • Atterberg limits testing
  • Compaction and moisture content tests
  • Consolidation and permeability testing

Specialty testing beyond these services, including advanced strength or consolidation testing, may be coordinated through qualified specialty laboratories as needed.

Construction Materials Testing

Tri Star provides construction materials testing and observation services to support quality control and quality assurance during construction. Our services focus on verifying that materials and workmanship comply with project specifications, approved mix designs, and applicable ASTM and TxDOT requirements.

We work directly with contractors, engineers, and owners to provide timely field support, clear documentation, and reliable test results that keep projects moving and minimize delays.

Construction Materials Testing Services Include:

  • Earthwork and Subgrade
  • Concrete
  • Hot Mix Asphalt Concrete (HMAC)
  • Foundations and Structural Observations

Testing and observations are performed by certified technicians in accordance with project specifications and applicable standards, with an emphasis on clear reporting and practical use of results.
