In the ever-evolving world of geomembrane welding, precision and reliability are not just goals; they are essential. The American Society for Testing and Materials (ASTM) has long been a cornerstone in establishing benchmarks for quality and performance in this field. With the recent introduction of ASTM standards D8580-24 and D8468-23, the industry is set to experience a significant transformation. In this article, we will explore how these new guidelines elevate the standards for geomembrane welding and how Global Source, a premier supplier of construction products, offers Leister’s innovative solutions to meet these advancements.
ASTM D8580-24: Standard Practice for Wedge Welding of Polymeric Geomembranes
ASTM D8468-23: Standard Practice for Data Recording Procedure for Welding Devices Used to Produce Thermal Fusion Welds in Geomembrane Systems
ASTM D8580-24: Elevating Wedge Welding Practices
The newly published ASTM D8580-24 provides a comprehensive framework for wedge welding of polymeric geomembranes. This standard is designed to enhance the quality and consistency of welds by setting clear parameters for the welding process and equipment. Key highlights of this standard include:
- Comprehensive Parameter Display: Welding devices must exhibit all three critical welding parameters – temperature, speed, and pressure – ensuring that operators can closely monitor and adjust settings in real time.
- Closed-Loop Control Systems: Heat and speed must be controlled by closed-loop systems, which enhances precision and consistency throughout the welding process.
- Pressure Accuracy: Accurate pressure readings are crucial for achieving high-quality welds, and this standard mandates that welding machines display pressure with precision.
- Equipment Design: Welding machines should be designed without sharp edges that could potentially damage the geomembrane, ensuring a smooth and effective welding process.
- Data Acquisition: The inclusion of a data acquisition system is recommended to support quality control and provide valuable insights during the welding operation.
Global Source proudly offers Leister’s welding equipment, which is engineered to align perfectly with these requirements. Our machines feature integrated displays for welding parameters, advanced closed-loop control systems, and precise pressure readings. Additionally, the design prioritises safety and efficiency, eliminating sharp edges and including robust data acquisition features.
ASTM D8468-23: Enhancing Data Recording for Quality Assurance
The ASTM D8468-23 standard introduces rigorous protocols for data recording during thermal fusion welding of geomembranes. This standard focuses on:
- Minimum Data Requirements: Establishing the essential data that must be recorded during welding to ensure thorough quality control and detect any anomalies.
- Post-Welding Analysis: Using recorded data for comprehensive post-welding analysis, allowing for the verification that welds meet the required quality levels.

Leister’s commitment to quality is reflected in our advanced data recording capabilities. Our equipment is designed to seamlessly integrate with data acquisition systems, providing detailed records of every welding operation. This feature is crucial for both quality control and post-welding analysis, ensuring that all projects adhere to the highest standards of performance.
