Services
Boring Log Software
LOGDRAFT creates detailed boring and monitoring well installation logs with 2D cross-sections and tabular reports. Designed for geotechnical engineers, it ensures compliance with ASTM and AASHTO standards. The software supports customizable forms and integrates with field data for accurate subsurface analysis.
Cement Testing Software
QC-Concrete reports compressive strength tests and flexural beam results for cement products. It aligns with ACI 301 standards and provides statistical analysis for mix performance. The tool streamlines quality control processes for construction material testing labs.
Soil Test Reporting
Our soil testing packages handle sieve analysis, triaxial shear, consolidation, and California bearing ratio tests. Software includes CLSuite, LabSuite, and Enterprise Suite for comprehensive geotechnical data reduction. Tools support ASTM D2435 and AASHTO T 99 standards for accurate soil classification.
Field Density Reporting
QC-Density calculates and reports field density test results for construction projects. The software ensures compliance with compaction standards and integrates with lab data for cohesive quality control. Ideal for infrastructure and earthwork applications.
Software Licensing
Our site licensing model allows unlimited installations within an organization, eliminating per-seat fees. Licenses cover network deployment, laptops, and temporary field offices. Updates and email support are included free for the first year, with optional maintenance contracts available.
