Field investigation tells us where to look. Our laboratory tells us exactly what we're dealing with. As a fully equipped geotechnical lab, Group Tesla Engineering runs the full range of soil mechanics testing in-house — turning raw samples into the verified data behind every foundation recommendation we issue

Core Tests We Perform

• Grain Size Distribution (Sieve & Hydrometer Analysis)

Determines the proportion of gravel, sand, silt, and clay in a soil sample — the foundation of soil classification

• Atterberg Limits (Liquid Limit, Plastic Limit, Plasticity Index)

Measures the moisture content thresholds at which fine-grained soil changes behavior — critical for assessing shrink-swell risk and soil classification

• Standard & Modified Proctor Compaction Test

Determines the optimum moisture content and maximum dry density a soil can achieve — the benchmark used to control fill and embankment compaction on site

• California Bearing Ratio (CBR)

Assesses soil strength for pavement and road subgrade design, indicating how well a soil will support traffic loading

• Direct Shear & Triaxial Shear Strength Tests

Measures the shear strength parameters — cohesion and internal friction angle — that determine bearing capacity and slope stability calculations

• Consolidation (Oedometer) Test

Predicts how much and how fast a soil will settle under sustained load — essential for long-term settlement forecasting on fine-grained soils

• Moisture Content & Specific Gravity

Fundamental index properties used across nearly every other geotechnical calculation

• Permeability (Hydraulic Conductivity) Test

Measures how easily water moves through soil — informing drainage design, seepage analysis, and groundwater-related risk

• Unconfined Compressive Strength (UCS) Test

Determines the compressive strength of cohesive soils and rock, used in foundation and slope design

• And More

Why It Matters

Field data tells us where the risk might be. Lab data tells us exactly how much risk there is, in numbers we can defend. We run these tests ourselves, in our own facility, precisely so nothing gets lost — or altered — between the sample and the report

What You Get

Every test result is compiled into your project's geotechnical report, interpreted by our engineers into clear, actionable design recommendations — and, as with all our official documentation, verified through our QR-coded authentication system
