Soil reports for:

ADU

New building

Pool

Retaining wall

Addition

Our firm provides comprehensive soil reports and geotechnical (soil) engineering services and prepares detailed geotechnical reports to support the design of foundations and structures. These soil reports are used by contractors, architects, civil engineers, and structural engineers during the planning and design phases of development projects.

Each soil report includes:

• A detailed description of site conditions encountered during the investigation.

• A compilation of geotechnical data obtained from field exploration, laboratory testing, and review of public records from local building departments.

• Engineering analyses and design recommendations for foundations, site grading, and drainage control.

• A discussion of seismicity and geotechnical hazards such as liquefaction, or slope instability, along with mitigation recommendations, if required.

Our soil field exploration services include:

• Mapping of surface geologic units and identification of adverse geotechnical or geologic conditions (e.g., faults, landslides).

We provide:

Geotechnical soil reports and liquefaction studies including:

• Foundation, drainage & grading recommendations

• Surface soil & groundwater evaluation

• Seismic hazard evaluation

• Soil bearing capacity analysis

• Borehole drilling & ASTM-standard laboratory analysis

• Compaction test for retaining wall, pool -backfill

• Percolation test

• Logging of Drilled Borings

  Logging drilled borings involves documenting subsurface conditions encountered during drilling. A geotechnical engineer prepares a boring log that typically includes:

  Information Recorded

  • Boring location, elevation, and drilling method

  • Sample intervals and types (SPT, Shelby tube, core)

  • Soil/rock classifications (USCS for soils/rock)

  • Moisture / Density conditions

  • Visual-manual classification (color, grain size, plasticity, structure)

  • Blow counts (SPT N-values) or other in-situ test results

  • Groundwater observations

We operate an in-house soil and rock testing laboratory, which allows us to provide timely and cost-effective testing to determine the properties of soil materials. This integrated approach ensures efficient coordination between field investigation, laboratory testing, and engineering analysis.

For Your Backfill Project

No matter the type of project — whether it’s pool backfill, retaining wall backfill, keyways, utility trenches — our team is here to help. We provide reliable backfilling test services to ensure your project is completed efficiently, and to the highest standard.

The Proctor Compaction Test, named in honor of Ralph Roscoe Proctor, is a laboratory method to determine maximum dry density of soil by determining the optimal moisture content at which a given soil will become most dense, accommodate 4in or 6in Soil Compaction Molds for native soil and imported materials as quarry fines or base rock. The test is commonly used for engineering applications in accordance to ASTM standards to determine how on-site measurements compare with the Proctor test results in the determination of soil density.

Soil Liquefaction

Soil liquefaction occurs when loose, water-saturated soils temporarily lose strength during strong cyclic loading such as earthquake shaking. When this happens, the ground can behave like a fluid rather than a solid, which may lead to foundation settlement, ground deformation, and structural damage.

Based on this analysis, we develop practical geotechnical recommendations to help mitigate these seismic hazards or design foundations that can safely accommodate potential ground movement.
