A comprehensive support method for soil analysis that covers everything from preliminary surveys to meeting acceptance criteria.

In construction projects, the disposal of construction leftover soil involves complex procedures, and a single mistake can lead to serious risks such as work stoppages or legal penalties. This service provides a total solution that offers everything from planning the preliminary investigation necessary for soil disposal, on-site sampling, high-precision chemical analysis, selection of optimal disposal sites, to support for notifications to authorities, all in a one-stop service. We fully meet over 45 strict standards that vary by region and disposal site (including dioxins, oil content, fluorine, etc.) and comply with volume-based sampling specifications (such as mixed method at five locations). Through GeoTech's integrated management process, we eliminate waste in each step, significantly reducing analysis costs while ensuring strict compliance and smooth progress of construction.
