Thoroughly alleviating buyers' concerns and psychological barriers regarding underground contamination! An investigation that leads to a smooth price agreement with a sense of security based on scientific data.

This service transparently clarifies the most concerning uncertainty for buyers in land sale transactions, which is the presence or absence of underground soil contamination, through a scientific approach, providing absolute peace of mind regarding the transaction. By proactively disclosing historical investigation results and sampling analysis data from the seller's side, it completely eliminates the buyer's doubts about environmental risks, allowing for dramatically smoother price negotiations and condition settings. Because there is objective certification from a third-party organization, a clear agreement that satisfies both parties can be achieved, preventing the deal from falling through and leading to a secure acquisition of assets. This plan serves as an environmental countermeasure solution that reliably demonstrates the safety of underground areas during real estate sales, sincerely protecting the corporate social credibility and the asset value of important land. Please feel free to entrust this to us with confidence.

basic information

This is a specification standard for high-precision voluntary soil surveys that fully comply with Article 5, Paragraph 1 of the Soil Contamination Countermeasures Act and relevant technical standards of related laws. In the historical investigation, public notification documents, past aerial photographs, and administrative information such as local history are analyzed from multiple perspectives to accurately determine the risk of contamination. In the sample collection process, core cutters that can drill through paved surfaces and simple boring machines capable of dry excavation are used, ensuring strict procedures to completely prevent secondary contamination. Collected soil and groundwater samples are managed in dedicated containers in a cool, dark place at 0 to 4°C, and the leaching and content of specific hazardous substances are measured rigorously. We provide extremely precise data based on objective facts.

Applications/Examples of results

It is used as environmental risk adjustment data for the objective asset value (real estate appraisal) required when obtaining loans from financial institutions, as well as for evaluating environmental liabilities of owned real estate in corporate business revitalization and M&A, and for site risk management as part of obtaining and maintaining ISO 14001 certification. Additionally, it plays a decisive role as a seller-led defense measure before contracts to completely eliminate troubles such as being claimed for huge damages after soil contamination is discovered post-land transaction. Furthermore, it is widely utilized in construction practices for preventing the spread of contamination to surrounding groundwater due to excavation work, managing the quality of on-site remedial soil, and making pre-judgments for sorting and processing to dramatically reduce disposal costs for surplus soil.
