Construction precautions
1. Foundation treatment: Clean the surface of the geotextile membrane, ensuring that the substrate is flat, the soil is solid, and there are no unevenness, cracks, sharp objects, stones, iron wires, wooden sticks, etc. Within the anti-seepage range, the grass and tree roots should be removed, and weed control agents should be sprayed.
On the contact surface with the membrane, a layer of sand or clay with small particle size should be laid as a protective layer, and the thickness of the protective layer should not be less than 30 cm.
Laying method:
1. Lay in a certain direction, but do not pull too tightly. Leave a certain amount of expansion and contraction to adapt to the deformation of the substrate.
2. A PE film with a certain width reserved on both sides of the geotextile and a non adhesive layer of PET fabric (i.e. edge throwing) should be laid. When laying, the direction of each unit of geotextile should be adjusted to facilitate the welding of the two unit geotextiles
3. After laying the geomembrane, it should be pressed with a sandbag to prevent wind and sand from affecting the welding of the edge of the geomembrane in the next step
4. Geomembrane welding. Joint treatment is a key construction procedure, usually using hot welding method. The surface of the PE film is heated to melt, and then fused into a whole through pressure
5. For the laid geomembrane, the edge joints must be free of oil, water, dust, etc
6. Before welding, adjust the two sides of the PE single film at the joint to overlap a certain width, which is generally 6-8 cm and flat without wrinkles
7. Use a dedicated welding machine for welding
