Proper installation begins with foundation preparation, including leveling and compaction of the subgrade. The composite drainage net must be laid smoothly and tightly against the prepared surface, avoiding twists, folds, or overlaps. Overlapping sections require secure fixation using U-shaped nails or specialized connectors, followed by thorough inspection and backfilling procedures to ensure optimal performance.
