PE Lining

① Development of a new waterproof installation using fixing members

• Perfect resolution to PE sheet drop-off for fixture installation
• Wet installation available
• PE sheet peeling issue resolved

② Improved structural stability, durability and economic feasibility

• Improved PE sheet attachment strength by increasing the fixing force of PE sheet

③ Improved constructability

• Significantly improved installability and economic efficiency compared to adhesive Installation

• It is a waterproof lining with improved durability, workability, and economic efficiency and perfect waterproof by using double panel members to fix the PE sheet joint.
• By using a double-panel fixing member to secure stability between the PE sheet and the concrete structure, the workability and durability are superior to the non-adhesive lining using fixtures, and the initial cost is reduced compared to the adhesive PE sheet waterproof lining.

Conventional adhesive and non-adhesive installation

• 

  Adhesive : Epoxy Installation

  Cracked concrete structure → Leachate inflow

  Reduced adhesion due to dew condensation and moisture

• 

  Non-adhesive : High-frequency fusion

  PE sheet of the fixture falls off during use after installation

  Limited fixing area

  Separation and Delamination

Separation and Delamination

• Enhanced durability
• Excellent installability and economy
• High airtightness secured

Features

• ① The joint fixing member composed of the reinforcing plate and the sealing plate is lined on the wall of the water tank through a fusion to provide excellent sealing power and improved durability regardless of fatigue accumulated due to repeated contraction and expansion depending on water level changes.
  [Patent No. 10-2178357]

• ② It is a a water tank lining with joint fixing members to further improve the watertightness of the inside of the water tank by fusing a polyethylene finishing sheet between sealing plates fused to the water tank and by sealing between the sealing plates with a finishing material.
  [Patent No. 10-2178357]

Features and Advantages

• ① Enhanced leak prevention through reinforced watertightness

• ② Enhanced durability (perfect resolution of peeling/falling of PE sheet)

• ③ Improved durability compared to the fixture installation

• ④ Reduced initial cost and improved installation process compared to adhesive installation

• ⑤ Reduced life cycle cost through improved durability

  - Reinstallation cost (One time or more)

  - Maintenance and management fee

• ⑥ Secured hygiene by using joint fixing members that are harmless to the human body

  - Secured reliability by using NSF61 and WRAS-certified materials
