Borehole Drilling & SPT

Soil investigation with standard penetration test

To investigate subsurface soil and rock strata through borehole drilling and Standard Penetration Test (SPT) — providing critical input for foundation design, settlement analysis and bearing capacity computation.

What We Do

  • Rotary & percussion drilling rigs
  • Standard Penetration Test (SPT N-value)
  • Borehole logging by qualified geologist
  • Disturbed & undisturbed sampling
  • Ground water table identification
  • Permeability tests (in-situ)
  • Rock coring & RQD measurement
  • Variable depths: 6m to 60m

Methodology

Site reconnaissance → borehole layout per project → drilling using rotary/percussion rigs → SPT at 1.5m intervals → soil sampling (SPT spoon & UDS) → ground water observation → rock coring (if encountered) → field log preparation per IS 1892.

Deliverables & Outcomes

We deliver comprehensive reports and data that guide your project planning and decision-making.

  • Geotechnical Investigation Report
  • Bore log with stratigraphy
  • SPT N-value variation chart
  • Soil classification (IS 1498)
  • Ground water profile
  • Recommended foundation design
