Installing geomembrane lining systems is a complicated process that is generally carried out by trained engineers and technicians. Various specialized welding techniques, site preparation, and installation expertise are required to ensure that any geomembrane lining system is properly employed. The following is a general, yet illustrative, geomembrane installation process:
Quality Assurance Inspection: The following items are reviewed to ensure quality geomembrane installation:

• Surface conditions met all requirements before the lining was laid
• The geomembrane rolls were deployed and identified correctly
• The anchor system was done correctly
• The anchor trench and the placement of the lining were all done correctly
• The correct welding equipment was used
• The quality control devices were operating correctly
• Verified the fusion welding seaming and/or extrusion welding seaming
• All repairs were completed
• Correct pipe penetration
• The seam crossings were accurate
• The installation was done per the original design
• The documentation of the installation was completed
