Geogrid’s BLOS System Offers Sustainable Water Solution for Aging Buildings
LAS VEGAS, NV – As cities grapple with aging infrastructure and increasing environmental concerns, a South Korean startup is offering a novel approach to water purification in older buildings. Geogrid, led by CEO Kim Ki-hyun, is pioneering “upcycling prop tech” with its Building Oasis System (BLOS), a smart IoT water control system designed to improve water quality without replacing existing pipes.
Upcycling Prop Tech: A New Trend
The concept of upcycling prop tech, which enhances the functionality and value of existing buildings through technology, is gaining traction amid climate concerns, rising construction costs, and urban density. This approach aligns with ESG (Environmental, Social, and Governance) principles by focusing on “space playback through technology” rather then traditional remodeling.
BLOS: Purifying Water at the Source
Geogrid’s BLOS system aims to address water quality issues common in buildings with aging plumbing. The system utilizes ionization technology to sterilize, remove rust, and eliminate scale, improving water quality to drinking water standards within 2-8 weeks, according to the company. testing in a 50-year-old Seoul apartment and a high school cafeteria reportedly confirmed the water’s potability.
The system also incorporates AI-based real-time water quality monitoring, enabling building managers to proactively identify and address potential problems.

CES 2025 and Global Interest
Geogrid showcased its BLOS system at CES 2025, drawing attention from European buyers focused on ESG initiatives. A representative from a European hotel chain reportedly expressed strong interest, stating that BLOS aligns with their company’s ESG goals.
Beyond Water Purification
“The United States has a serious PFAS detection issue in old building piping,” said Geogrid Chung Hyung-wook, head of Strategic Planning Team. He added that BLOS is unique in combining semi-permanent ionization technology with AI analysis. “The concept of ‘life integers’ has begun not only for drinking water but also to wash dishes, cleaning and meals.”
Geogrid has already secured a supply contract with PT Eastern Diabel Route in Indonesia and is establishing partnerships with companies in Thailand, Vietnam, and Taiwan.The company’s focus extends beyond water purification to creating sustainable spaces through technology that revitalizes aging buildings.

A Shift in Construction Strategy
The traditional approach of demolition and new construction faces limitations in terms of cost, environmental impact, and resident disruption. Upcycling prop tech offers a viable option. Geogrid’s BLOS, for example, can be installed in buildings awaiting reconstruction approval, providing access to clean tap water as a practical solution for both public and private sectors.
Experts predict that upcycling prop tech startups focused on areas such as idle space utilization, waste material-based materials progress, and AI energy management will contribute to this growing trend. This represents a new avenue for growth and a strategic imperative for the real estate and construction industries.
From the initial source to every point of use, technology is redefining the value of space.Upcycling prop tech, which revitalizes existing assets through technological innovation, is emerging as a key solution for aging buildings.

What is “Upcycling Prop Tech”?
“Upcycling prop tech” enhances the functionality and value of existing buildings through technology. It’s a lasting approach that aligns with ESG (Environmental, Social, and Governance) principles, focusing on “space playback through technology” rather than traditional remodeling or new construction. This is particularly relevant given climate concerns, rising construction costs, and urban density.
How Does geogrid’s BLOS System work?
The BLOS system uses ionization technology to purify water.Its main functions are:
Sterilizing water
Removing rust
Eliminating scale
According to the company, these processes can improve water quality to drinking water standards within 2-8 weeks. The system also features AI-based real-time water quality monitoring.
What Are the Benefits of the BLOS System?
The BLOS system offers several advantages:
Improved Water Quality: Addresses water quality issues common in aging buildings.
Cost-Effective: Avoids the expense of replacing existing pipes.
Sustainable: Aligns with ESG principles by extending the lifespan of existing infrastructure.
Proactive Monitoring: AI-based monitoring helps building managers identify and address potential problems.
Has the BLOS System Been Tested?
Yes, testing of the BLOS system in real-world scenarios has been conducted. The article mentions testing in a 50-year-old Seoul apartment and a high school cafeteria, with confirmed potability of the water.
What is the Significance of CES 2025 for Geogrid?
Geogrid showcased its BLOS system at CES 2025. This event provided a platform to gain global interest and attract potential buyers. They drew attention from European buyers, specifically those focused on ESG initiatives.
What is the United States’ PFAS problem?
The provided content states that “The United States has a serious PFAS detection issue in old building piping.” PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that can contaminate drinking water and, as stated in the article, are an issue in older buildings.
Beyond Water Purification, What else Does BLOS Offer?
Geogrid’s BLOS system aims to provide a comprehensive approach to water quality management. The system is designed to ensure clean water not only for drinking, but also for dishwashing, cleaning, and meals.
