　　1. Bentonite waterproofing blankets are relatively heavy; it is recommended to use a loader for handling and installation.
　　2. The bentonite waterproofing blanket shall be joined by lapping.
　　3. Any equipment used to lay bentonite waterproofing blankets must not be driven over already installed geosynthetic materials. During the installation of bentonite waterproofing blankets, the outdoor air temperature must remain between 0°C and 40°C.
　　4. When installing bentonite waterproofing blankets on slopes greater than 10%, the number of longitudinal overlaps should be minimized, and the blanket on the slope must extend at least 1,500 mm beyond the toe line. D. We will install the bentonite waterproofing blankets strictly in accordance with the installation design drawings submitted to the supervising engineer, unless otherwise directed by the owner or the supervisor.
　　5. All exposed edges of the bentonite waterproofing blanket must be immediately weighted down with sandbags or other heavy objects to prevent the blanket from being blown away or pulled out of the perimeter anchorage trench. The bentonite waterproofing blanket should not be unrolled in windy conditions to avoid being lifted by the wind.
　　6. The installation of the bentonite waterproof blanket must ensure direct contact with the underlying foundation, and any wrinkles must be eliminated. Any wrinkles, folds, or bulges may lead to similar issues in other geosynthetic materials within the soil layer. To prevent such problems, we will address them by re‑laying the bentonite waterproof blanket or by cutting and repairing it, in accordance with the technical specifications.
　　These are the primary construction methods for sodium‑based bentonite waterproofing blankets. It is essential to follow the instructions carefully and perform the work correctly.
