EVA Self-Adhesive Waterproof Sheet

Tired of geomembrane delamination, sharp puncture damage, low-temperature cracking and extra glue costs in tunnel construction? Our EVA self-adhesive waterproof sheet is integrated durable membranes made by one-step lamination of EVA polymer sheet, hot melt adhesive and protective release liner, cutting extra coating procedures for underground anti-seepage projects.   We supply flexible rolls with thickness of 1.0/1.2/1.5/2.0mm, width from 2 to 4m and minimum length of 20m to fit various tunnel and basement layouts. This waterproof membrane boasts 18MPa tensile strength, over 650% elongation and ≥400N puncture resistance, effectively preventing damage from sharp stones and steel nails. It remains crack-free at -35℃ and withstands 0.3MPa water pressure for 24 hours without leakage. Featuring strong self-adhesive property, it tightly adheres to cast-in-place concrete to form an integrated leak-proof layer, and maintains stable performance after long-term alkali, thermal and UV aging.
