Our Services

Drilling, engineering and testing from a single team — the full subsurface-to-structure picture for owners, contractors and design professionals.

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.

Our certified field technicians are on site when you need them, with calibrated equipment and same-day reporting that keeps the schedule moving and the inspector satisfied.

Every result is logged, reviewed by a licensed engineer and delivered digitally, so owners, contractors and design teams are all working from the same numbers.

Capabilities

  • Soil compaction & nuclear density testing
  • Proctor & moisture-density relationships
  • Concrete field testing — slump, air, temperature
  • Concrete cylinder casting, curing & breaks
  • Asphalt density, coring & plant QC
  • Masonry, grout & mortar testing
  • Proof-roll observation & subgrade evaluation
  • Footing & bearing-grade verification (DCP)
  • Aggregate gradation & quality testing
  • Fireproofing thickness & density

Geotechnical Engineering

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

We plan each exploration program around your structure and site, then translate boring logs and lab data into clear recommendations for foundations, earthwork, pavements and retaining structures.

Our engineers stay engaged through construction, so when field conditions differ from the report they get resolved quickly — not escalated.

Capabilities

  • Geotechnical investigations & reports
  • Shallow & deep foundation recommendations
  • Bearing capacity & settlement analysis
  • Slope stability & retaining wall design
  • Pavement design & evaluation
  • Seismic site classification
  • Ground improvement & soil stabilization
  • Groundwater & dewatering evaluation
  • Forensic & distress investigations
  • Construction-phase consulting

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.

Owning our drilling equipment means we control mobilization dates, sample quality and safety on every boring. Truck-, track- and ATV-mounted rigs let us reach sites other firms can't.

Every crew is OSHA-trained, calls in utility locates before mobilizing and leaves a clean, safe site behind.

Capabilities

  • Hollow-stem & solid-stem auger borings
  • Standard penetration testing (SPT), auto hammer
  • Shelby tube & undisturbed sampling
  • Rock coring (NQ / HQ)
  • Track & ATV rigs for limited-access sites
  • Monitoring well & piezometer installation
  • Direct-push environmental sampling
  • Pavement & concrete coring
  • Infiltration & percolation testing
  • Hand auger borings & test pits

Special Inspections

Code-required special inspections under IBC Chapter 17, performed by certified inspectors and reported directly to the building official.

We coordinate the statement of special inspections with the design team and jurisdiction, then deliver timely daily reports and a clean final letter at closeout.

Capabilities

  • Reinforcing steel & embedded items
  • Structural steel, bolting & welding
  • Post-tensioned concrete
  • Structural masonry
  • Deep foundations — piles, caissons & drilled shafts
  • Spray-applied fireproofing
  • Helical piles & anchors
  • Soils & controlled fill

Laboratory Testing

An in-house soils, concrete and aggregate laboratory delivering accurate, defensible results with fast turnaround.

Our lab follows ASTM and AASHTO procedures under a documented quality system, with equipment calibrated on a regular schedule and every result reviewed before release.

Capabilities

  • Moisture content & Atterberg limits
  • Grain-size & hydrometer analysis
  • Standard & modified Proctor
  • California Bearing Ratio (CBR)
  • Unconfined compression & triaxial
  • Consolidation testing
  • Concrete compressive strength
  • Grout, mortar & masonry prisms
  • Aggregate gradation & specific gravity
  • Organic content & pH
