Scenario: A company is building a new landfill and needs to choose a geomembrane liner for the waste containment area. They are considering XR-5 geomembrane due to its strength and chemical resistance.
Task:
**1. Chemicals XR-5 resists:** * **Methane:** A common landfill gas that can be hazardous. * **Heavy metals:** Metals such as lead, cadmium, and mercury can leach from waste and contaminate groundwater. * **Organic compounds:** Waste decomposition can release harmful organic compounds like volatile organic compounds (VOCs). **2. Seamless installation benefits:** Seamless installation with hot-air welding creates a continuous, leak-proof barrier, preventing leachate from escaping the landfill and contaminating the surrounding environment. It eliminates potential weak points or gaps that can occur with other types of installation methods.
