Rising Building Material Prices Lead to More Buildings Abandoning Pipe Replacement; Patent Technology to Create 'Pipe-Within-Pipe' Without Damaging Existing Pipes to Be Exhibited

P.C.G. Technica Inc. (Headquarters: Nagoya City, Aichi Prefecture; President & CEO: Kaname Fujii), a company specializing in water and drainage pipe regeneration, will exhibit at the 'International Construction & Surveying Expo' held at Makuhari Messe from June 17 (Wed) to 20 (Sat), 2026, introducing its patented technology 'FRP Lining Method' that regenerates building pipes without damaging them.

Currently, in the construction industry, prices of steel and resin pipes continue to rise, leading to numerous cases where the budget for pipe replacement (full replacement) in condominiums and office buildings far exceeds initial plans. In response, PCG Technica offers a solution that dramatically reduces overall construction costs by regenerating existing pipes instead of replacing them, minimizing the need to purchase expensive new piping materials.

Increasing Number of Buildings Unable to Upgrade Due to Rising Material Prices

Construction material prices remain high due to historic yen depreciation, soaring raw material prices, rising labor costs from labor shortages, and increased logistics costs due to truck driver overtime regulations.

In condominiums and office buildings, the number of structures over 30 years old requiring pipe replacement is increasing. However, construction costs often exceed initial estimates, forcing delays in upgrades. Since pipes are located inside buildings, full replacement requires demolition of walls and floors. In addition to the cost of new piping materials, expenses for demolition, waste disposal, and interior restoration also arise, causing overall construction costs to balloon.

Under these circumstances, the option of 'regeneration instead of replacement' is gaining traction. The FRP Lining Method minimizes the use of new piping materials by utilizing existing pipes, thereby suppressing overall construction costs.

Three Reasons Why the FRP Lining Method Reduces 'Cost'

Dramatic Reduction in Material Usage

Instead of ordering thousands of meters of new pipes, a strong FRP membrane is formed inside the existing pipes. By minimizing raw material usage, the method avoids risks associated with price fluctuations in the construction materials market.

Reduction in Ancillary Construction Costs by 'Not Damaging'

FRP Lining can be implemented with minimal demolition of walls and floors. This allows combined reduction of labor and material costs associated with demolition, waste disposal, and interior restoration.

Durability 'Better Than New'

FRP excels in corrosion resistance and seismic performance and does not rust. A single application can extend pipe lifespan by over 20 years, also reducing future maintenance costs (life-cycle costs).

What is the 'FRP Lining Method' That Extends Building Life Without Demolition and Allows Construction While Occupied?

The solution that resolves these issues is the FRP Lining Method developed by our company. This patented technology internally forms a new pipe within existing pipes using special fabric and resin. Since construction does not require wall demolition, resident relocation is unnecessary, enabling shorter construction periods, cost reduction, and reduced waste. It is widely adopted in public facilities, housing complexes, hospitals, and more.

Six Features of the 'FRP Lining Method'

① Six patented methods that form a new pipe inside existing pipes without damaging walls

② Simultaneously achieves waste reduction, shortened construction periods, and cost reduction, minimizing resident burden

③ No need to enter intermediate floors; construction limited to top and bottom floors only, with short water shutdown times

④ Regenerates pipes with holes or cracks, enhancing the building's structural strength and seismic resistance, contributing to disaster prevention

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

⑥ Awarded the Aichi Environmental Prize and Nagoya Mayor's Prize in 2012

Highlights Include Deteriorated Pipe Examples and Construction Video Footage! Sample Pipes and Equipment Also Introduced

At the exhibition booth, we will display actual pipe samples that have undergone regeneration work. Additionally, demonstration videos conveying the atmosphere of real construction sites and introductions to equipment used will deepen your understanding of the method. Our staff will be stationed at the booth, ready to answer questions about the method and construction details, provide consultations tailored to your building or condominium, and offer detailed explanations of specific construction cases (including building age, scale, cost estimates, and work duration). Take this opportunity to directly experience how our groundbreaking technology addresses societal infrastructure aging issues, particularly drainage pipe problems that become apparent in summer, at our booth.
