Structural Waterproofing System Engineering Guide
A procurement-oriented engineering guide for bituminous membrane systems used in underground structures, transportation tunnels, and concrete-integrated waterproofing projects.
Bituminous Geomembrane: A Structural Bonded Waterproofing System
Bituminous geomembrane is a structural waterproofing layer designed to bond permanently with concrete or substrate surfaces. Its performance is defined by adhesion behavior rather than free membrane strength.
It is commonly used in environments where water migration occurs along structural interfaces.
Key engineering functions:
✔ Interface sealing between concrete and soil structures
✔ Crack-bridging under structural movement
✔ Continuous waterproof barrier in confined systems
✔ Long-term adhesion stability under load cycles
