Elves capping sheet

Three-layered sheet with reinforcement fabric on both sides of microporous film

Elbes capping sheet is a three-layered sheet consisting of microporous film with reinforcing fabric on both sides. Gas-permeable tarpaulins are sheets that are both impermeable and gas-permeable.

High Density Polyethylene Sheet “Gundel Sheet HD Series

Standard for final disposal High-density polyethylene sheet

It is a global standard impervious sheet that has been installed in 50 countries around the world for a variety of applications including final waste disposal sites, reservoirs, and detention ponds. It has excellent physical properties such as tensile strength and chemical resistance. It is classified as a high elasticity type by the Japan Waterproofing Engineering Association.

Thermoplastic Rubber Sheet “TPE Sheet”, “FPA Sheet

Rubber sheet blended with resin to provide thermoplasticity

By blending vulcanized rubber with a resin such as polyethylene, this product combines rubber elasticity and thermal bonding properties. There are two types of FPA sheets: TPO-PP sheets using polypropylene and TPO-PE sheets using polyethylene. It is classified as a medium elasticity type by the Japan Waterproofing Engineering Association.

Low Density Polyethylene Sheet “Gundel Sheet LD Series

Polyethylene sheet with both flexibility and strength

This is an impervious sheet made of low-density polyethylene material that combines the excellent physical properties and softness of polyethylene sheet. It falls under the medium elasticity type in the classification of the Japan Waterproof Engineering Association.

Stud Liner,” “YMS Lock,” and “Max Lock.”

Molds made of the same material as the impervious sheet are embedded in concrete to improve watertightness and save space.

Special components embedded in concrete greatly improve workability and imperviousness. Fixing to concrete structures and pipe penetration is where the most attention must be paid in impervious construction. We offer the best dedicated components for better quality.

Water barrier sheet protection mats “Gandel Mat” and “Appeal

Superior “penetration resistance” prevents damage to impervious sheets.

Protective mats are placed above and below the impervious sheet to prevent damage to the sheet. By employing protective mats with excellent “penetration resistance” (resistance to penetration by protrusions), it is possible to prevent damage and leakage of the impervious sheet due to direct contact with protrusions.
