Reasons for Actual Damage to The Geomembrane of Construction Materials
What is the actual damage to the construction geomembrane film?
It is extremely fragile during transportation and construction, and the technique of laying a cover or gravel layer on a composite geomembrane is incorrect. Damaged holes will inevitably affect the seepage prevention of the project. Or lack of geotextile padding material protection.
There are special standards for material selection, construction, welding methods, and requirements. Unsuitable stone size, damage, and leakage still occur in actual engineering. The damage site usually occurs in the thermal expansion of the impervious HDPE low cost textured geomembrane.
The damage site typically occurs when the water-tight thermal expansion, the geosynthetic material is flattened and adhered tightly to the base and technical support layers, and the pleats caused by the incorrect layup and overlay.
When laying, the composite geomembrane is flattened with sandbags, and the operator must not wear hard bottom shoes and spike shoes. Until the protective layer is completed. Heavy objects and vehicles must not be placed directly on the membrane.
