• Base Layer Inspection:

Ensure that the base layer surface is smooth and free from stones, roots, sharp objects, or any debris that could damage the geomembrane. The geomembrane should have rounded bends rather than rigid right-angle structures.

• HDPE Geomembrane Slope and Connection Preparation:

Connections between the HDPE geomembrane on the tank slope and pipes or concrete structures may experience significant tension, potentially leading to detachment at the joints. Therefore, before welding, ensure an overlap width of at least 10 cm, with adequate allowance for movement, and avoid horizontal seams on slopes.

• Weld Quality Control:

Welds should be smooth, consistent in thickness, and free of debris or excess weld material. Ensure the surrounding base material remains undamaged. After welding, conduct a comprehensive inspection to ensure a 100% pass rate on weld quality.
