Before laying, a comprehensive inspection of the laying base should be carried out in conjunction with relevant departments. Construction can only be carried out after the following conditions are met.

1. The laying base shall be solid and flat, and there shall be no tree roots, debris, stones, concrete particles, steel reinforcement heads, glass chips or other debris that may damage the geotextile within a vertical depth of 25mm. When laid on backfill soil, the compaction degree of backfill soil shall not be less than 95%. The previous process (civil engineering or geotextile membrane laying) has been completed and accepted.

2. The laying of geotextile film first involves transporting the cut and numbered geotextile film blocks according to the on-site measurement situation to the corresponding positions on site. Check if the laying area matches the numbering of each film, and once confirmed to be correct, transport the film into position and immediately use sandbags for temporary anchoring. Check the overlap width of the membrane, which should not be less than 10cm.

3. When laying construction in special areas such as the foot of the slope, turns, and intersections of the slope in the storage area, it is necessary to check the smoothness and smoothness of the soil foundation during turns, and avoid negative slopes. When laying the membrane, it should be relaxed as much as possible to avoid suspension or wrinkling of the geotextile due to tension.

4. During the laying process, the appearance of the membrane should be checked at any time to see if there are any defects such as water marks, pitting, holes, creases, etc. If any unqualified products are found, they should be replaced immediately.
