Geotechnical Investigation Services
Borings · Lab Testing · Foundation Design

Subsurface investigation and PE-signed foundation recommendations for developers, contractors, and architects across NJ, NY, and PA. Drilling, in-situ testing, laboratory analysis, and construction-phase support — delivered on the schedules lenders and permit desks actually need.

Full-Scope Geotechnical Engineering

Soil Borings & Sampling

Standard Penetration Test (SPT) borings, undisturbed Shelby-tube samples, and rock coring across the site footprint, coordinated with utility mark-outs and access constraints.

Geotechnical Lab Testing

AASHTO- and ASTM-compliant lab suite: gradation, Atterberg limits, moisture/density, consolidation, direct shear, triaxial, and CBR testing as scope demands.

Foundation & Retaining Wall Recommendations

Shallow-foundation bearing capacity, deep-foundation options (driven piles, drilled piers, micropiles), lateral earth pressures, and settlement analysis in a signed & sealed report.

Construction-Phase Support

Pre-bid geotechnical clarifications, RFI response during construction, and field observation of subgrade preparation, deep-foundation installation, and compaction.

  • Building additions, vertical expansions, and reroofs
  • Retaining walls, excavations, and SOE design
  • Bridge, culvert, and pavement subgrade evaluations
  • Deep-foundation and pile-driving programs
