JM Elite EVA Sheet

l Outline l

Being a product made of EVA resin contained with vinyl acetate, it is a product that can be produced by mixing VLDPE, LLDPE etc. if required, and it is widely used not only for water-proofing of tunnels but also for the water treatment facility of artificial lake, waterway etc. due to the excellent flexibility and coefficient of extension.


l Features l

• Durability
  The resistance for the pressure of concrete placing is excellent as the mechanical strength is excellent, and there is almost no change of prooperty even though buried for a long time.
• Chemical Resistance
  It is stabilized for the acid․alkali and other chemicals in concrete or earth and sand, and the underground leachate is not penetrated.
• Water resist
  It is almost not affected by the climate change with the workable temperature range of -30℃~120℃, and the responsiveness for the contraction, expansion, crack of structure is excellent with the coefficient of extension of over 600%.
• Construct ability
  Being a construction method which performs thermosetting with welding machine, the adhesion strength is excellent and it can be checked if it is completely welded or not by use of air tester.

l Use l

Road Tunnel, Railroad Tunnel, Utility Tunnel, Power Tunnel, Underground Structure, and other water-proofing construction to cut off waters etc.



l Size l

• Thickness : 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm
• Width : Over 2m

l Construction Method l

1. Shotcrete surface arrangement
2. Actual measuring of the internal diameter of tunnel and preparation of truck
3. Fix the water-proof sheet on the shotcrete surface
4. Bond the water-proof sheets with the thermosetter after making them overlapped by more than 80mm
5. Air test of sheet connecting area
