embedding. Highway anti-seepage treatment, take minimum seams of construction as principle: the central median when the lower part Impervious generally use a cloth membrane 200-300g / m. Based on the water pressure requirements of engineering design. When the base layer is concrete structure, the construction conditions, to determine the width and length of geomembrane:. // F, to determine the thickness of the geomembrane, climate conditions:. // F, construction capacity. According to the actual size, life and other application conditions of the project, and according to the project nature exposure, the application site.
