High polymer self adhesive EVA /HDPE (non-asphalten-based) waterproof membrane is a kind of waterproof material widely used in underground project, it can bond with concrete layer tightly. After Membrane bonding with concrete, water can be blocked between membrane and concrete, which can improve the reliability, which is specially pre-laid membrane for underground engineering.

After the waterproof layer construction is completed, the steel bars can be tied and concrete can be poured immidiately.
 

Adhesive+Sand membrane structure:
Self-adhesive HDPE different types:
1). Color sand: Color sand+ Non-asphalt base adhesive + High polymer sheet
2). White sand:  White sand+ Non-asphalt base adhesive + High polymer sheet
3). Smooth surface:  PE release film+ Non-asphalt base adhesive + High polymer sheet
