Soil investigation to prove safety through voluntary pre-transaction historical research to eliminate the risk of defects in sales that cause the cancellation or delay of land transactions.

In real estate transactions, the discovery of soil contamination after the contract is signed is the biggest concern that can lead to the cancellation of the deal or prolonged litigation. To clear the seller's contractual liability for non-conformity and the risk of defects in the sale in advance, and to achieve a safe and smooth land sale, conducting a voluntary soil investigation by the seller themselves is an extremely effective strategy. This technical explanation document introduces specific methods to accelerate real estate transactions while eliminating risks. First, through a voluntary land quality survey that thoroughly investigates the past usage history of the land, the potential for the underground infiltration of specific harmful substances can be diagnosed early. This objective assessment dispels the buyer's concerns about environmental risks, allowing negotiations to proceed overwhelmingly favorably and swiftly. The rapid sampling and high-precision official analysis provided by Geotech, a designated investigation agency of the Ministry of the Environment, maximizes the transparency of the transaction and perfectly prevents any legal troubles after the handover.

basic information

This is a specification for a highly efficient voluntary soil survey that responds to rapid real estate transactions. During the historical investigation phase, digitized past public data and high-resolution aerial photographs are utilized to assess risks in the shortest possible time. For on-site sampling, lightweight and compact equipment such as simple penetration testing machines and hand augers are used to minimize pavement damage while completing sample collection in a short time. Analysis is conducted based on standard public methods at registered measurement certification facilities (such as Ministry of the Environment Notifications No. 18 and No. 19), ensuring that data on leachate and content is confirmed in a short period, and reliable reports are issued quickly.

Applications/Examples of results

It is utilized for the early sale of commercial land and business real estate, as well as for clearing risks when transferring land to real estate developers. By presenting it as evidence of safety to buyers in the early stages of negotiation, it completely prevents contract cancellations and unjust depreciation demands. Additionally, it is ideal for pre-acquisition surveys of land for new construction projects with tight development schedules, as well as for pre-environmental risk assessments of auction and public sale properties. It is widely used as an important environmental tool to support the asset liquidity strategies of companies that want to facilitate smooth financing and land disposal according to plan.
