EVA All-in-one Transparent Waterproof Sheet, VE All-in-one Transparent Waterproof Sheet, EVA All-in-one Embossed Waterproof Sheet, ECB Separate-type Waterproof Sheet, ECB All-in-one Waterproof Sheet
EVA, which stands for Ethylene Vinyl Acetate that is a kind of chemical resins, and ECB which stands for Ethylene Copolymer Bitumen have the following characteristics.
Both materials have excellent durability and make it possible to carry out thermal adhesion between junctures of each sheet. And it is possible to realize the perfect waterproof by testing the adhesion performance, based on the observation of high-pressure air inserted into the adhered parts.

Comprehensive review -Possible to carry out easy construction due to the good flexibility, sticking sheets into flexion of shotcrete in side the tunnel
-Economical construction works
-Curtailing work period
-Making up for the weak points like drooping of waterproof sheets at ceiling part or occurring damages, which are regarded as problems of the construction method
-Good condition for concrete placement
-Inevitable damage on waterproof sheet due to use of roundels, and poor workability due to complicated processes -Improvement of poor workability of the separate type
