High-precision analysis that accurately identifies specific hazardous substances by industry type.

This is a specialized soil investigation solution for the redevelopment of factory sites and business premises where the use of various harmful substances is a significant concern. It fully visualizes the unique legacy risks associated with each industry and ensures compliance with the acceptance standards for construction soil. Based on advanced knowledge as a Ministry of the Environment designated investigation agency, it conducts high-precision leaching and content analysis strictly in accordance with official methods, breaking down the manufacturing processes of each industry multilayered, and provides perfect official evidence that meets the legal requirements demanded by disposal sites and municipalities. Instead of blindly incurring high costs to inspect all items, it optimizes investigation costs by logically screening target substances through accurate historical research and designing optimal sampling plans, while thoroughly managing soil contamination risks. This approach eliminates serious business risks such as project delays due to sudden contamination discoveries during construction and soaring disposal costs due to rejection of soil acceptance. This service is the optimal choice for thoroughly reducing your business risks and maximizing cost performance, serving as a solid foundation to ensure safety in many construction projects.
