From small-scale fish farming to mega-landfill projects, geomembranes are the indispensable solution wherever waterproofing and seepage control are required. However, achieving optimal performance critically depends on the welding process.

Carbon black is a highly refined, nano-grade carbonaceous material used as the core functional additive in HDPE geomembrane (with its content precisely controlled at 2.0%-3.0%). Sichuan Zhonglong employs approximately 2.5% carbon black (combined with 97.5% High-Density Polyethylene virgin resin) for ensuring our products comply with GRI and ASTM standards.

As environmental protection increasingly becomes a nationwide topic, the existence of landfills is no longer just about burying waste properly. People's focus has shifted from "filling" to "prevention"— preventing seepage, leaks and pollution. Because once groundwater and soil are contaminated, the cost will not merely be only site cleaning needed, but a chain reaction in the ecosystem. To defend this barrier, the key is not on the surface, but the invisible underground geomembrane. In this “chain system”, Zhonglong has proven that air pressure testing is not a “formality”. In contrast, it’s the crucial final step in construction.
