Advanced Soil Testing Laboratory
Soiltechnics operates a premier commercial soil mechanics testing facility in Selangor, Malaysia. Equipped with multi-station automated load frames and high-precision electronic transducer sensors, we deliver rapid and precise soil characterization.
Classification & Index Tests
Fundamental properties determining soil behavior and USCS/AASHTO classification:
- ✓ Natural Moisture Content
- ✓ Liquid Limit, Plastic Limit & Plasticity Index
- ✓ Wet & Dry Sieve Grain Size Analysis
- ✓ Sedimentation by Hydrometer for silts/clays
- ✓ Specific Gravity (Pyknometer method)
Oedometer Consolidation
Automated motorized load regulation determining settlement parameters:
- ✓ Compression Index (Cc) & Recompression (Cr)
- ✓ Preconsolidation Pressure (Pc)
- ✓ Coefficient of Consolidation (Cv)
- ✓ Swelling Pressure & Swell Index
- ✓ Zero dead-weight disturbance
Triaxial Shear Compression
Full shear strength characterization under confining cell pressures:
- ✓ Unconsolidated Undrained (UU)
- ✓ Consolidated Undrained (CU + Pore Water)
- ✓ Consolidated Drained (CD) for slope stability
- ✓ Total & Effective Shear Parameters (c, φ, c', φ')
- ✓ Specimen sizes: 38mm, 50mm, 70mm, 100mm
Direct Shear Box Testing
Rapid drained shear strength determination:
- ✓ Standard 60mm & 100mm shear boxes
- ✓ Peak and residual angle of friction
- ✓ Granular fill, sand, and interface friction
- ✓ Motorized continuous shear displacement
Permeability & Seepage
Hydraulic conductivity testing under controlled heads:
- ✓ Constant Head Permeability for sands/gravels
- ✓ Falling Head Permeability for cohesive soils
- ✓ Triaxial cell flexible-wall low permeability
- ✓ Automated Flowtron back-pressure control
Compaction & CBR
Earthwork subgrade and pavement foundation parameters:
- ✓ Standard Proctor (2.5kg rammer)
- ✓ Modified Proctor (4.5kg heavy rammer)
- ✓ Unsoaked & 4-Day Soaked CBR with swell
- ✓ Optimum Moisture Content (OMC) & MDD
