GSE HDH High-Temperature Liners
GSE HDH is a specialist HDPE geomembrane for containment duties with elevated operating temperatures. We supply and install this liner for projects that need a product selected for the actual temperature and chemical exposure.


What is GSE HDH?
GSE HDH is a specially formulated High-Density Polyethylene geomembrane engineered for high-temperature applications. It is manufactured with an advanced resin blend to provide superior thermal stability, stress crack resistance, and chemical durability.
Key Features of GSE HDH High Temp Liner
-
Operating Temperature: Up to 100°C
Perfect for solar ponds, brine containment, and high-altitude mining environments where surface temperatures spike beyond standard liner tolerances. -
Superior Oxidative Resistance
Formulated for long-term UV exposure in arid and equatorial climates-ideal for African sun. -
High Chemical Resistance
Resistant to acids, leachates, brines, and industrial effluents common in African mining and processing industries. -
GRI-GM13 Compliant with High Temp Additive Package
Manufactured to international standards, with additional heat-resistant additives for enhanced performance. -
Available in Textured or Smooth Finishes
Textured surfaces improve slope stability, friction angles, and liner-to-soil interface performance.

Installation and technical guidance
Design and procurement inputs
Confirm the complete time-temperature exposure, liquid chemistry and supporting-layer compatibility with the manufacturer for the exact supplied grade.
Provide the product grade or performance specification, drawings or BOQ, quantities, site location and required date. We will define supply, delivery and any agreed installation and QA/QC responsibilities in the quotation.
Request a product-specific quotation →Installation and QA/QC
Specify roll and batch traceability, material acceptance, joint inspections and appropriate tests for the selected liner system.
Use the current supplied-product procedure and the approved project inspection plan. Define responsibilities and acceptance criteria before installation.
SELECTION · SPECIFICATION · PROJECT SUPPLY
Choose the right specification
Containment is selected around the stored liquid, ground conditions, exposure and required barrier system.
- Confirm polymer, thickness, surface finish and the actual operating temperature and chemistry.
- Review the subgrade, protection layers, anchorage, penetrations and joining method.
- Use the current supplied-grade datasheet and project acceptance criteria, with material and installation records.
Define the quality records
Specify roll and batch traceability, material acceptance, joint inspections and appropriate tests for the selected liner system.
For a useful quotation: send the grade or performance specification, quantity, location, required date and scope. Availability, delivery and installation responsibilities are confirmed in the quotation.
