2. When carrying out the next process or adjacent construction, the bentonite waterproof pad that has already completed the process should be properly protected and must not be damaged by anyone.

3. Try to avoid wearing spiked shoes or high heels to step on the bentonite waterproof pad as much as possible; Vehicles and other machinery are not allowed to crush the bentonite waterproof pad.

4. In the construction of waterproof blankets, the already laid waterproof blanket should be constructed with HDPE film or a 300mm thick clay protective layer on the same day. If the construction of HDPE film or clay protective layer cannot be completed on the same day, the waterproof blanket should be covered to prevent it from being hydrated and exposed to strong sunlight due to rain and snow.

5. After the completion and acceptance of the anti-seepage and waterproof construction project of the single-layer lining of the waterproof blanket, it should be quickly backfilled with soil, sand or stone particles with a specific gravity greater than 2.0. To prevent damage to the waterproof blanket during backfilling, the backfill soil should not contain crushed stones with a particle size greater than 10mm, and the thickness of the backfill soil should not be less than 30cm. The backfill soil should be backfilled and compacted in stages, with a compaction degree not less than 85%.
