Maintaining geomembranes involves regular inspections to detect any damage, punctures, or wear that could compromise their integrity. Areas of concern include seam quality, surface condition, and the geomembrane's anchorage system.
Minor damages can often be repaired on-site using patching techniques or welding, depending on the material. Preventative measures, such as ensuring the removal of sharp objects from the substrate before installation and using protective layers or geotextiles to guard against punctures and abrasions, are also important.
