At Moment Engineering, we bring deep field experience to every geotechnical drilling project. Our team performs efficient, code-compliant subsurface investigations using both truck-mounted and hand auger drilling methods. From residential lots to commercial and hillside sites, we deliver accurate soil data for liquefaction analysis, percolation testing, slope stability, and foundation design.

We routinely perform deep borings and subsurface investigations to support:

• Liquefaction analysis in seismic zones, including detailed profiling to depths exceeding 50 feet where required by local agencies and CBC guidelines.

• Percolation testing for seepage pit design and stormwater management, meeting county health department requirements and providing critical data for stormwater infiltration systems.

• Commercial developments such as solar carports, EV charging stations, and large-scale utility projects, where soil bearing capacity and settlement risk are critical to design and permitting.

• Hillside construction and slope stability analysis, including exploratory drilling near descending slopes for shear strength and creep potential.

• New subdivisions and infrastructure projects, where comprehensive boring logs, soil classification, and laboratory testing are necessary for grading and foundation design.

Our field crews are trained in both hollow-stem auger and solid-stem drilling methods, using mobile equipment capable of accessing tight urban lots, commercial sites, and undeveloped terrains. All borings are logged by trained professionals or geologists in accordance with ASTM and local jurisdiction standards.

Whether you’re working on a custom home, commercial plaza, or a public improvement project, Moment Engineering brings reliable field support and expert interpretation to every drilling program — ensuring your design starts with the right data.
