Experience the latest technology to prevent agingマンション drainage pipe troubles, with numerous construction samples and case studies on display

P&G Technica Co., Ltd. (Headquarters: Nagoya City, Aichi Prefecture, Representative Director: Kaname Fujii), which specializes in the renovation business for water supply and drainage pipes, will exhibit at the "Comprehensive Building Exhibition" held from July 2 (Thu) to 3 (Fri), 2026, at Wink Aichi, introducing its patented "FRP Lining Method" for renovating building pipes without demolition.

Currently, the construction industry is facing continuous price increases for pipe materials such as steel and resin pipes, leading to frequent cases where the budget for pipe replacement work (complete replacement) forマンション and buildings significantly exceeds the initial plan. In response, our company offers a solution that "renovates pipes instead of replacing them," minimizing the purchase of expensive new pipe materials and dramatically reducing the overall cost of the work.

Buildings that cannot be renovated" due to soaring material prices

In addition to historical yen depreciation and soaring raw material prices, rising labor costs due to labor shortages, and increased logistics costs due to restrictions on truck driver overtime hours, construction material prices remain high.

Inマンション and buildings, the number of structures requiring pipe replacement after 30 years of age is increasing. However, in some cases, replacement must be postponed because the construction costs far exceed the initial estimate. Since pipes are located inside the building, complete replacement involves demolition of walls and floors. In addition to the cost of new pipe materials, demolition costs, waste disposal costs, and interior restoration costs are incurred. As a result, construction costs escalate.

Amidst this situation, the option of "renovation instead of replacement" is beginning to expand. The "FRP Lining Method" is a construction method that minimizes the use of new pipe materials by utilizing existing pipes, thereby suppressing the overall cost of the work.

3 Reasons why the FRP Lining Method can suppress "prime costs"

1. Overwhelming reduction in material usage

Instead of ordering thousands of meters of new pipes, a strong FRP membrane is formed on the inside of existing pipes. By minimizing the amount of raw materials used, we avoid the risk of price fluctuations in the building materials market.

2. Cutting of ancillary construction costs by "not demolishing"

The FRP lining can be installed with minimal demolition of walls and floors. Labor and material costs for demolition, waste disposal, and interior restoration can be reduced collectively.

3. Durability is "better than new"

FRP excels in corrosion resistance and seismic resistance and does not rust. A single application can extend the life of the pipes by more than 20 years, also suppressing future maintenance costs (life cycle costs).

"FRP Lining Method" that extends the life of buildings without demolition and can be done while living in them?

Our company's developed FRP lining method resolves these issues. This method is a patented technology that forms a new pipe internally using special cloth and resin inside existing pipes. Since it can be installed without demolishing walls, residents do not need to move out, leading to shorter construction periods, cost reduction, and waste reduction. It is widely adopted in public facilities, housing complexes, and hospitals.

6 Features of the "FRP Lining Method"

1 A patented method that forms a new pipe inside existing pipes and can be installed without demolishing walls

2 Simultaneously achieves waste reduction, shorter construction periods, and cost reduction, minimizing the burden on residents

3 No need to enter intermediate floors; installation is only on the top and bottom floors, with short water outage times

4 Renews pipes with holes or cracks, improving the structural strength and seismic resistance of the building itself, thus contributing to disaster prevention

5 Applicable to public sewage systems, a highly reliable technology adopted by both public and private sectors

6 Received the Aichi Environmental Award and Nagoya Mayor's Award in 2012

Highlights include examples of deteriorated pipes and construction footage! Sample pipes and equipment will also be introduced

▲Sample display area during exhibition ▲2025 Exhibition booth at the successful Comprehensive Building Exhibition

At the exhibition booth, we will have samples of pipes that have undergone renovation work. You can deepen your understanding of the method through demonstration videos that convey the atmosphere of actual construction sites and introductions of the equipment used. Our staff will be stationed at the booth, so we can provide detailed guidance not only on questions about the method and construction details but also on consultations tailored to the condition of your building orマンション, and even specific construction examples (age of building, scale, cost estimates, number of workdays, etc.). On this occasion, please come and see for yourself at our booth how our groundbreaking technology solves the problem of aging social infrastructure, especially the drainage pipe issues that become apparent in the summer.
