Geotechnical (Soil) Engineering & Testing for Smarter, Safer Projects
Calgeotech Engineering Consultants, Inc. provides dependable reporting, field testing, and engineering support for
residential and commercial construction—so you can reduce uncertainty and move forward with confidence.
We support projects throughout the entire Bay Area—including San Francisco, the Peninsula, the South Bay, the East Bay, and the North Bay. Call (925) 551-0774 to request a consultation.
Geotechnical Engineering & Soil Reports
Get clear, build-ready documentation for new construction, additions, and site development. We evaluate subsurface conditions and provide practical recommendations that support foundation design, grading, and long-term performance.
Our reports can address soils, settlement concerns, expansive soil, and project-specific risks—so engineers and builders have actionable guidance, not guesswork.
Need a soil or geotechnical report? Call (925) 551-0774 to get started.
Compaction Testing
Verify proper compaction for pads, trenches, and backfill with reliable on-site testing. We document density results and help confirm that site prep meets project requirements before the next phase of work.
Good compaction reduces the risk of future settlement and helps keep schedules on track by catching issues early.
Schedule compaction testing: (925) 551-0774.
Materials Testing
Materials testing services that support quality control and straightforward inspections. We help verify field conditions and document results so specs are met and project records are clear.
From verification testing to documentation support, we keep the process efficient and easy to understand for teams in the field.
Need materials testing? Call (925) 551-0774.
Slope Stability Evaluations
Assess slope conditions and stability risks before they become expensive problems. We evaluate site factors that may affect performance and provide practical guidance for safe development and long-term protection.
If you’re seeing movement, cracking, or drainage-related slope issues, we can help identify causes and recommend next steps.
Request an evaluation: (925) 551-0774.
Liquefaction Evaluations / Assessment
Understand liquefaction risk and how it may impact your project. We review site conditions and provide assessment-focused reporting to support safer foundation planning and informed decision-making.
If you’re planning in higher-risk areas, early evaluation can reduce surprises and help keep designs aligned with requirements.
Discuss your site: (925) 551-0774.
Retaining Wall Evaluations
Evaluate existing or planned retaining walls with a focus on performance, site conditions, and risk reduction. We help identify contributing factors and provide guidance that supports safer, more durable results.
Whether it’s a design review, movement concern, or site constraint, we deliver clear recommendations your team can act on.
Need a retaining wall evaluation? Call (925) 551-0774.
Drainage Issues / Drainage Review
Drainage problems can drive settlement, slope movement, and long-term property damage. We review site drainage conditions and provide practical recommendations to help manage runoff and protect structures.
From single-property concerns to broader site planning, we support homeowners and project teams across our Bay Area service area with responsive guidance and documentation that’s easy to follow.
Have a drainage concern? Call (925) 551-0774.
Limited Access Drilling
Now we can provide geotechnical drilling in a timely manner and at a competitive price. Our limited access rig can drill borings in the limited access areas using big beaver or trailer mounted rig. Below are the tasks we can do: • Call for underground utility clearance (USA) for free • Apply for drilling permit for the cost of permit plus 5% • Sampling every 5 ft using Modcal (MC) or Standard Penetration Test (SPT) samplers • Soil testing of the samples per ASTM standard • Log and profile soil using gINT program
