GSE HDH
Previously HLR/Goliath/High Temp
High-temperature resistant geomembranes for long-term barrier performance
Designed for durability in extreme environments
Containment systems operating under sustained high temperatures demand more than conventional geomembranes can offer.
GSE® HDH high-temperature resistant geomembranes are engineered to meet these challenges. Manufactured with advanced high-temperature resistant resins and Solmax’s proprietary stabilization package, GSE HDH maintains its strength and durability at continuous exposure up to 95 C (203 F). The material has been rigorously tested and complies with both US PPI TR4 and EN ISO 9080 standards for high-temperature liquid conveyance.
Laboratory results confirm that GSE HDH offers superior resistance to oxidation, puncture, and stress cracking. It retains mechanical performance and barrier integrity where standard liners fail, making it the ideal choice for high-heat temperature containment environments.
Built for long-term performance, tested in real-world conditions
GSE HDH combines chemical resistance, physical strength, and thermo-oxidative endurance in one solution. It is especially well-suited for use in demanding applications such as:
Thermal Energy storage systems, where hot water is stored for energy extraction
Bioreactor landfills, where microbial activity generates elevated internal temperatures
Mine leach pads, where heated process solutions are commonly used
Secondary containment systems for oil & gas infrastructure exposed to hot liquids
Food processing plants and industrial ponds managing thermally active waste streams
Hot liquid storage tanks, process water systems, and wastewater treatment applications
In all these environments, GSE HDH ensures continuous protection with minimal risk of degradation. It is compatible with standard welding equipment and QA/QC protocols, and remains weldable even near freezing temperatures, enabling year-round installation and tie-ins for future phases or repairs.
