depend on the specific project, used thickness, whether the geomembrane is produced by new material and whether the protective layer of geomembrane meets the construction requirements
Geomembrane damage ratio field bottom damage lay and cover drainage gravel / sand protection reach up to 97% geomembrane defect wasteyard construction cost conventional quality assurance (CQA) program are more concerned about the welding quality the whole area of seepage-proof geomembrane conduct necessary detection table data and quote and analysis geomembrane construction quality assurance should focus on key impervious barrier leakage locations prospection and electrical leakage locations detection to ensure the quality of anti-seepage engineering is more efficient and more economical means
When introduing geomembrane quality system, US experts said that statistical material show that the geomembrane breakage caused by construction accounted for over 60% of all geomembrane breakage quality assurance
