Black geomembranes are not approved by some consumers and professionals, because it is difficult to detect damage to geomembranes on a black surface to carry out remedial actions. The white layer on the black geomembrane makes it easy to detect damage. Also, due to the effect of the black body, black geomembranes tend to absorb sunlight, while the white surface reflects light, and in this case, the surface temperature will be 25˚C to 30˚C cooler than black geomembranes, and thus thermal expansion and distortion during installation. will be reduced and we will have an easier and better installation.
The temperature difference between day and night leads to the expansion and contraction of geomembranes, so the installer should use more geomembranes when installing during the day so that there is no problem in case of contraction. In geomembranes with a white layer, the installation is done with less and smaller wrinkling, because the expansion and contraction, according to what was described, happens less. Another advantage of low temperature in the white surface geomembrane is the reduction of moisture evaporation of the soil below the geomembrane.
