Streamlining the backfilling work for pipe penetration! Achieving further total cost reduction! A new construction method for backfilling pipe penetrations. Patent obtained!
The "Kantaro Construction Method" is a new method for backfilling piping penetrations that combines the aluminum foil composite pad material "Kantaro" with the water-stopping special grout mortar "Kan Grout." It streamlines the backfilling work for piping penetrations, achieving water-stopping effects and reducing total costs. Additionally, by using filling material (rock wool) for "Kan Grout," it effectively reduces vibrations transmitted to the structural concrete compared to conventional mortar filling methods (cushioning effect). 【Features】 ■ Exhibits excellent effectiveness in water-stopping at the backfilled area simultaneously with the backfilling of piping penetrations. *1 ■ Resolves deficiencies and defects in backfilling work, achieving stable quality. ■ Allows for the omission of waterproofing processes after backfilling work, reducing total costs. *1 ■ By using filling material (rock wool) for Kan Grout, it effectively reduces vibrations transmitted to the structural concrete compared to conventional mortar filling methods (cushioning effect). *1: It does not guarantee that water will not leak under any circumstances. *For more details, please refer to the PDF materials or feel free to contact us.
