How to solve the water leakage after the construction of GCL?Taian Hongyuan Geosynthetics Co., ltd., as a manufacturer of GCLs, takes everyone to learn together!
1. If there is accumulated water on the ground, the drainage operation must be carried out first. The compaction degree of the basic treatment plain soil is not less than 85 percent.
2. If there is moisture on the ground, drainage measures should be taken after laying to prevent early hydration of the GCL.
3. The GCL should be at least 15cm lower than the main part and 25cm side, and can be fixed with nails (also bamboo nails) and washers at 30cm intervals.
4. After the construction of the GCL, the construction personnel must pay attention to prevent the damage of the bentonite cushion.
5. In order to prevent the early hydration caused by rain, 3-5cm thick cement mortar should be laid after the construction of the cushion layer to prevent the early hydration of the waterproof layer in contact with water. In general, the total compacted volume of liming soil is not less than 10cm.
6. Before the next process, check whether the bentonite waterproof layer is lost. If there is any loss or damage, use sealant or bentonite powder to repair.
7. In order to increase the watertightness of the overlapping part of the bentonite pad, it can be reinforced with bentonite powder or bentonite sealant.
