What we do

Three disciplines. One team.

From the drill rig to the lab to the jobsite, we collect the data, engineer the answers and verify the work gets built right.

Construction Materials Testing

Field and laboratory testing that verifies soils, concrete, asphalt, masonry and steel meet project specifications — from the first lift of fill to the final pour.

  • Soil compaction & nuclear density testing
  • Proctor & moisture-density relationships
  • Concrete field testing — slump, air, temperature
  • Concrete cylinder casting, curing & breaks

Geotechnical Engineering

Subsurface investigations and engineering analysis that turn soil and rock data into practical, buildable foundation recommendations.

  • Geotechnical investigations & reports
  • Shallow & deep foundation recommendations
  • Bearing capacity & settlement analysis
  • Slope stability & retaining wall design

Drilling & Subsurface Exploration

Our own crews and rigs collect high-quality soil and rock samples on your schedule — on open sites, tight urban lots and everywhere in between.

  • Hollow-stem & solid-stem auger borings
  • Standard penetration testing (SPT), auto hammer
  • Shelby tube & undisturbed sampling
  • Rock coring (NQ / HQ)

How we work

From first boring to final pour — no hand-offs.

When the drillers, lab, field technicians and engineer all work for the same company, information moves in hours instead of days.

Questions get answered by the people who collected the data. Changed conditions get resolved on site. And you have one accountable partner for every test, boring and report on the project.
