Accurate measurements and reasonable planning should be carried out according to design requirements to determine the laying direction and cutting size of the geomembrane.

Provide professional training to construction personnel, enabling them to be familiar with the construction process and technical specifications. Equip complete construction equipment and testing instruments to lay a solid foundation for high-quality construction.

When laying the geomembrane, the principle of "first the slope, then the bottom" should be followed, and the laying should be carried out from top to bottom. Keep the membrane surface flat, with appropriate tension to avoid wrinkles and suspension. 

Sufficient lap width should be reserved between adjacent geomembranes, generally not less than 10 centimeters, to ensure firm splicing. During the laying process, the membrane surface should be inspected in a timely manner. If any damage is found, it should be marked and repaired immediately.

Welding is a crucial part of geomembrane construction. Professional welding equipment should be used, and appropriate parameters such as welding temperature, speed, and pressure should be set according to the material and thickness of the geomembrane. 

Trial welding is required before formal welding to detect the welding quality, ensuring that the welds are firm, uniform, and free of air holes. After welding, conduct inflation tests and peel tests on the welds to ensure that the welding strength meets the design requirements.

Establish a complete quality control system and strictly supervise the entire construction process. Every link, from the inspection of raw materials upon entry, quality sampling during construction, to acceptance inspection after completion, should be strictly controlled. 

Regularly evaluate and analyze the construction quality, identify and solve problems in a timely manner, ensuring that the geomembrane construction quality meets or exceeds national standards and design requirements.
