Product Description
Bentonite waterproof blanket is a composite waterproof material made from natural bentonite through needle punching or weaving techniques. It has the following characteristics:
Bentonite waterproof blanket (GCL) is a new type of geosynthetic material. It is composed of graded natural sodium based bentonite particles and corresponding additives mixed evenly. Through special processes and equipment, the high expansion sodium based bentonite layer is uniformly and firmly fixed between two layers of geotextiles with the strength of thousands of fibers. The bentonite waterproof blanket (GCL) made from this not only has the sealing, isolation, and reinforcement effects of geotextiles, but also has excellent waterproof and anti-seepage performance, It is one of the indispensable and important materials in many modern civil engineering projects.

Installation Instructions
Bentonite waterproof blanket (also known as bentonite waterproof pad) is a composite waterproof material made from natural bentonite through needle punching or weaving technology. When laying bentonite waterproof blankets, the following steps should be followed:
Preparation work: Before laying, ensure that the foundation surface is flat, clean, and free of oil, dust, and other debris. Defects such as cracks and hollowing at the grassroots level should be repaired.
Setting out and positioning: According to the engineering design requirements, mark a reference line on the foundation to determine the laying position of the bentonite waterproof blanket.
Laying method: The laying of bentonite waterproof blanket should be carried out from low to high, first laying the drainage layer, and then laying the waterproof layer.
Laying sequence: Starting from one side, lay the bentonite waterproof blanket flat on the foundation and gradually unfold towards the other side. During the laying process, the flatness and smoothness of the bentonite waterproof blanket should be ensured.
Lapping treatment: The overlapping of bentonite waterproof blanket should be done using a stitching method, and the stitching thread should be made of the same material as the bentonite waterproof blanket. The overlap should be kept flat and firm to ensure waterproofing effect.
Anchor treatment: Install anchors on the edges and drainage layer of the bentonite waterproof blanket to fix it on the foundation. The number and spacing of anchor pieces should be set according to the engineering design requirements.
Inspection and acceptance: After the laying is completed, the laying quality of the bentonite waterproof blanket is checked to ensure that it is laid flat, firm, and free from damage, hollowing, and other phenomena.
Construction requirements: During the construction process, relevant regulatory requirements should be followed to ensure the construction quality of the waterproof layer.
In short, when laying bentonite waterproof blankets, strict adherence to construction process requirements should be followed to ensure waterproofing effectiveness. Meanwhile, during the construction process, attention should be paid to construction safety and quality control to ensure the smooth progress of the project.
