In any civil engineering or major infrastructure project, understanding the subsurface condition is the absolute first step toward success and structural longevity. Soil and rock behaviors dictate how foundations must be designed, how risks are mitigated, and how budgets are optimized.

Our company provides comprehensive Geotechnical Investigation Services, utilizing advanced drilling technology and in-situ testing methods to deliver highly precise, actionable geological data for engineering teams worldwide.

Our Core Geotechnical Capabilities

We specialize in executing rigorous geological site campaigns across diverse and challenging environments, fully covering both onshore and water-bound locations:

1. Onshore & Surface Geotechnical Drilling

We mobilize specialized, high-capacity land rigs to handle variable soil matrices, mapping out complex geological strata for buildings, industrial treatment plants, and public utilities.

• Deep-hole borehole drilling through clay, sand, gravel, and dense alluvial layers.

• Continuous soil stratigraphic logging and profile mapping.

2. Offshore & Nearshore Marine Investigation

Navigating water boundaries requires unique technical expertise. We deploy drilling setups on marine platforms and jack-up barges to support coastal infrastructure, intake structures, and heavy pipeline alignments.

• Marine borehole drilling in shallow to deep water environments.

• Deep foundation sub-surface mapping under challenging tidal conditions.

3. High-Quality Soil & Rock Sampling

To preserve sample integrity for ultimate laboratory precision, our field engineers execute strict sampling standards:

• Undisturbed Sampling (UDS): Utilizing piston samplers and thin-walled tubes to retrieve high-quality cohesive soil samples without altering their natural shear strength or consolidation properties.

• Rock Core Drilling (Rock Coring): Advancing deep into underlying bedrock layers using diamond bits to recover solid cores for Total Core Recovery (TCR) and Rock Quality Designation (RQD) evaluation.

4. Advanced In-Situ Field Testing

We provide continuous, real-time ground parameters directly from the field through globally recognized testing methods:

• Standard Penetration Testing (SPT): Conducted at strict intervals in accordance with ASTM/JIS standards to evaluate soil density, consistency, and bearing capacity.

• Piezocone Penetration Testing (CPTu): Delivering continuous stratigraphic logging, pore pressure data, and soil behavior types.

• Field Vane Shear Testing (VST): Accurately measuring the undrained shear strength of sensitive, soft clay deposits.

5. Comprehensive Laboratory Testing & Engineering Reports

All recovered soil and rock samples are carefully preserved and transferred to our testing facility for rigorous physical and mechanical analysis (index and strength testing). Our licensed geotechnical experts then compile comprehensive engineering reports, providing clear foundation recommendations, settlement analysis, and soil parameters necessary for structural design.

Why Partner with Us?

• Proven Mobility: Fast mobilization of geotechnical teams, deep-drilling rigs, and specialized field equipment even across cross-border projects.

• Dual-Environment Expertise: Exceptional track record in managing both complex onshore land plots and demanding marine/nearshore environments simultaneously.

• Strict Compliance: Every step—from the initial field blow count to the final laboratory compression test—strictly adheres to international ASTM, BS, and Eurocode standards.
