Revitalizing Old Apartments with P.C.G Technica's Innovative Pipe Restoration Method

In the contemporary landscape of aging apartments, the need to address deteriorating plumbing systems becomes increasingly critical. P.C.G Technica, headquartered in Nagoya, Aichi, presents a groundbreaking approach at the upcoming R&R Architecture Regeneration Exhibition, held from December 9 to 11, 2025, at Tokyo Big Sight. Their patented technology, known as the FRP Lining Method, allows for the rejuvenation of pipes without the need to demolish walls or floors, thereby minimizing construction time, costs, and the impact on residents.

Understanding the Pipe Restoration Challenge

The aging infrastructure of condominiums poses significant challenges for management associations. As older apartments proliferate, the probability of leaks caused by corroded water and drainage pipes is rising alarmingly. Three primary issues arise for these management bodies:

1. Increased Leak Risks: Steel pipes coated with zinc, predominant until the mid-1960s, suffer from internal corrosion over time. Particularly, shared drainage systems experience heightened leak risks due to heavy usage.

2. Ambiguity in Responsibility: Determining whether leaks occur in shared areas (management responsibility) or private sections (owner responsibility) can often be complex. Costs for investigating the leak, compensating for damages, and repair can significantly strain the financial resources of management associations.

3. Heavy Construction Burdens: Traditional pipe replacement requires invasive modifications, resulting in noise, dust, prolonged periods without water, and additional stress on elderly residents who might need temporary relocation. The lack of consensus on such disruptive measures often leads to necessary renovations being indefinitely postponed. Additionally, many insurance plans do not cover damages due to aging pipes, placing further financial strain on management associations.

The Solution: FRP Lining Method

The FRP Lining Method, developed by P.C.G Technica, effectively addresses these challenges. This patented technology involves forming new pipes within existing ones using special resin and textiles, streamlining the restoration process by eliminating the need to break walls. The advantages of this technique abound:

• - Minimal Disruption: Residents can remain in their homes during the restoration process, substantially reducing construction timelines and costs, while minimizing waste.
• - Strength and Durability: This method enhances the structural integrity and seismic resilience of the entire building, contributing to disaster prevention measures.
• - Versatility: It is applicable not only in residential structures but also in public facilities and hospitals, underscoring its reliability.
• - Recognition: The method was awarded the Aichi Environmental Prize in 2012, reflecting its commitment to sustainable practices.

Key Features of the FRP Lining Method

1. Six patented methods for creating new pipes within existing ones without wall demolition.
2. Joint achievement of waste reduction, shortened construction time, and cost-effectiveness while lessening resident burden.
3. Reduces the need for access to intermediate floors, allowing for a quicker restoration process on upper and lower levels only, thus shortening water outage periods.
4. Repairs and revitalizes damaged pipes, ultimately boosting the building's structural robustness and earthquake resistance.
5. High reliability leads to adoption in both public and private sectors, including applications in municipal sewer systems.

Booth Highlights at the R&R Exhibition

The P.C.G Technica booth will display samples of pipes that have undergone restoration, alongside demonstration videos capturing the real-time application of their innovative techniques. Attendees are encouraged to engage with company representatives present to discuss specific building circumstances, potential case studies, and to ask detailed questions regarding the restoration process.

Message from CEO Kaname Fujii

“Japan's aging condominiums are confronting a significant challenge. The aging of plumbing systems, referred to as the 'blood vessels' of the building, leads to apprehensions regarding potential leak incidents, especially among management associations. Traditional methods require tremendous time and financial resources, alongside the burden this places on residents.

The FRP Lining Method's unique characteristics support long-term value retention of these properties by enhancing their durability and safety. Moreover, we take pride in our contribution to reducing environmental impact through waste minimization, highlighting our commitment to sustainability in the current era. We invite management associations and construction professionals to visit our booth for insights into how our technology can address the challenges of aging infrastructure effectively.”
