GEOSPATIAL EXPERTISE

Geotechnical Investigation & Soil Testing Services

Geotechnical Investigation & Soil Testing is critical for evaluating subsurface load-bearing parameters before deciding on foundation design. Beena Enterprises operates mobile drilling rigs and soil testing laboratories to deliver comprehensive geotechnical profiling.

Subsurface Borehole Profiling & Strength Analysis

A structure is only as safe as the soil beneath its foundation. We perform borehole drilling, retrieve undisturbed core samples, and run Standard Penetration Tests (SPT) at standard depth intervals. Our in-house soil labs analyze plastic limits, shear properties, density indices, and swell ratios. These parameters determine whether a shallow raft or deep piling foundation is required, keeping structures safe from unequal settlement.

Critical Soil Parameters Documented

  • Safe Bearing Capacity (SBC): Maximum allowable contact pressure to prevent shear failure.
  • Silt Factor & Plasticity Index: Evaluation of moisture sensitivity and clay swelling coefficients.
  • Hydrological Water Table Depth: Identification of water levels to design excavation dewatering loops.

Key Benefits of Our Approach

Prevents catastrophic building tilt, settlement cracks, or structural failures.

Optimizes foundation steel and concrete requirements, saving material costs.

Satisfies municipal building code clearances and structural audit norms.

Indispensable Applications

Commercial towers, industrial plants, and chimney foundation design.

Bridge piers, flyovers, and elevated transit structural column piles.

Landslide zoning, retaining wall layouts, and slope stabilization studies.

Execution Phase & Survey Workflow

Service Specific FAQs

For standard residential structures, we bore 10-15 meters, while high-rises or bridges require 20-30 meters or until hard rock is struck.

Yes, we test soil and groundwater pH, sulphate, and chloride levels to check if sulphate-resistant cement is needed in foundations.
