Field Density Log

Turn field density readings into clear, traceable soil compaction records—right where the work happens. Field Density Log is built for construction materials testing technicians, inspectors, geotechnical field staff, and QA/QC teams. Enter project-specific reference values and acceptance criteria, capture a field reading, and immediately see dry density, required dry density, percent compaction, moisture difference from optimum, and whether the result meets the criteria you entered. CALCULATE THE WAY YOU WORK • Gauge or direct dry-density entry • Wet density plus moisture • Sand-cone inputs • Known wet mass and volume • U.S. customary and SI units KEEP A RELIABLE FIELD LOG • Organize tests by project and Proctor profile • Record test number, location, lift, time, technician, equipment ID, and notes • Preserve the exact reference values and criteria used for each saved test • Keep drafts on device so an interruption does not erase your entry • Move quickly from one test to the next REVIEW AND SHARE • Search and filter saved tests • Review the inputs, calculations, criteria, and warnings behind every result • Export project records as CSV, PDF, or a shareable field summary • Share an export only when you choose BUILT FOR FIELD CONDITIONS • Core calculations, records, and export generation work offline after download • No account or sign-in • No ads or subscription • No app-integrated analytics or tracking SDK • Project data is not automatically sent to the developer; sharing occurs only when you choose TRANSPARENT RESULTS Field Density Log shows how each result was calculated, identifies incomplete or invalid inputs, and calls attention to values that should be checked. Acceptance thresholds and moisture limits come from your project profile rather than a hidden universal default. IMPORTANT Field Density Log is a calculation and recordkeeping aid. It does not replace approved project specifications, applicable test standards, calibrated equipment, laboratory results, or professional judgment. Always follow project requirements and direction from the responsible engineer or laboratory.
