Soil Properties Testing
|Hydraulic conductivity vs. pressure head|
Understanding site soil condition—such as infiltration rates, seepage, leakage, and contaminant transport—is invaluable in optimizing design for recharge, irrigation, groundwater remediation, landfill, and dam projects and more.
The DBS&A Soil Testing and Research Laboratory provides analyses of consolidated and unconsolidated materials (rock, soil, fly ash, waste rock tailing, slag, concrete, etc.). DBS&A’s certified technicians have provided quality soil testing results for modeling, construction, and geotechnical projects for clients around the world. We are recognized for our ability to develop and implement innovative testing techniques and procedures to meet our clients’ specific challenges, and to provide consistent and reliable results following standard testing methods, including:
Hydrologic properties analyses
- Saturated hydraulic conductivity
- Moisture retention properties
- Soil-water characteristic curves
- van Genuchten modeling parameters
- Hysteresis effects
- As-received soil water potential
- Effective porosity
- Water holding capacity
Consolidation and strength testing
- 1-dimensional swell and consolidation
- Triaxial strength and consolidation
- California bearing ratio (CBR)
Standard geotechnical testing
- Particle size analysis
- Proctor compaction testing
- Plasticity index
- Specific gravity
Project-specific customized analyses
