In the Philippine construction landscape, a project’s stability is entirely dependent on the ground beneath it. Inch-On Materials Testing Laboratory provides comprehensive Geotechnical Soil Investigations, centered on the Standard Penetration Test (SPT), to evaluate soil density and consistency. Our laboratory ensures that your site’s subsurface conditions are thoroughly analyzed to guarantee foundational integrity and safety for every structure.
Our geotechnical investigations utilize specialized equipment to provide a detailed profile of the soil’s engineering properties, strictly adhering to ASTM D1586 and DPWH standards.
Measuring N-values by driving a split-spoon sampler with a 63.5 kg hammer to determine soil shear strength and density.
Recording resistance at specific intervals to map soil strata and consistency.
Assessing soil type, color, and moisture in the field.
Correlating field data with Atterberg Limits and Sieve Analysis to classify soil according to the Unified Soil Classification System (USCS).
Using N-values to derive internal friction angles and undrained shear strength.
Providing the data necessary to determine the appropriate depth and type of foundation (shallow vs. deep piles).
Building on unverified soil in the Philippines—where seismic activity and varying soil conditions are common—can lead to foundation settlement, structural tilt, and catastrophic failure. Our reports provide the technical clarity needed to:
Meet all DPWH-BRS and local government requirements for building permits and safety clearances.
Prevent over-engineering (saving costs) or under-engineering (preventing failure) by knowing the exact bearing capacity of the soil.
Identify soft clay pockets or liquefiable sand layers before construction begins.
Secure the safety of residential, commercial, and infrastructure projects against the unique environmental challenges of the region.
We provide transparent reporting and realistic timelines to keep your project on track. Whether you are a contractor, developer, or structural engineer, we ensure your ground is fit for purpose.
