HY
Key facts
Two-cloth-one-membrane composite (e.g. 300g/0.75mm) or membrane with geotextile layers for basin and slopes, with anchorage, ballast and special treatment of the water-level fluctuation zone.
Configuration must be confirmed by project design documentsMaterial Configuration by Layer
| Layer | Recommended material | Function / rationale |
|---|---|---|
| Primary liner | Composite geomembrane / membrane + geotextile | Containment |
| Cushion | Staple geotextile | Puncture protection |
| Anchorage & ballast | Anchor trench, toe ballast | Uplift and sliding control |
| Fluctuation zone | Thicker cover + anti-slide measures | Wave and drawdown action |
| Cover | Soil / masonry / concrete | UV and mechanical protection |
| Note: configurations are common practice; the final system and specifications must follow the project design documents and governing codes. | ||

Frequently Asked Questions
What is special about the fluctuation zone?
It suffers wave wash, drawdown uplift and freeze–thaw together, so cover thickness, ballast and anti-slide detailing are increased and slope friction is raised.
