How is the GCL constructed?

1. The material of the GCL has a large dead weight, and it should be moved and laid with a shovel machine and a waterproof blanket lifting tool.

2. The connection of GCL material adopts the lap method.

3. When laying the GCL on a slope greater than 10%, the number of overlaps along the length of the slope should be minimized. The bentonite pad on the slope must exceed the slope foot line by more than 1500mm. We will lay strictly according to the design drawings of the GCL laying submitted to the supervision engineer, unless required by the owner or supervision.

4. Any equipment used for laying GCLs cannot be driven on the already-laid geosynthetics. When installing the GCL, the outdoor air temperature cannot be lower than 0 ℃ or higher than 40 ℃.

5. All exposed GCL edges must be immediately pressed with sandbags or other heavy objects to prevent the GCL from being blown by the wind or being pulled out of the surrounding anchor trench. GCLs cannot be deployed in windy weather to prevent them from being blown up by the wind.

6. The laying method of the GCL must ensure that the GCL is in direct contact with the ground below to eliminate wrinkles. Any folds, folds or arches may cause the same situation in other geotechnical materials in the soil layer. To avoid folds, folds and arches, we will re-lay or cut the GCL according to the technical instructions And patch to eliminate these problems.
