JMC Ltd. Completes CSWIP Geomembrane Welding Training

TWI Training and Examination Services recently delivered a CSWIP Level 1 Geomembrane Welding Training and Certification Course for candidates from JMC Ltd., held on 3–4 November 2026.

The two-day course focused on the heated wedge and extrusion welding of polyethylene (PE) membranes, providing candidates with practical training in techniques used for geomembrane installation and joining.

Delivered by TWI Plastic Welding Trainer Daniel Kearney, the training covered key aspects of geomembrane welding, helping candidates develop their understanding of the processes, equipment and practices involved in producing reliable, welded joints.

Practical knowledge is an important part of geomembrane welding, where factors such as joint preparation, equipment settings, process control and inspection all contribute to weld quality. Understanding potential defects, appropriate working practices and health and safety requirements is also essential when carrying out welding work on site.

TWI's geomembrane welding training is designed to support individuals looking to develop their skills in plastics welding, including those involved in membrane installation and maintenance, as well as experienced welders seeking to extend their knowledge and pursue recognised qualifications.
