  Installation Guidelines (Summary)

  1. Prepare the subgrade: Level surface; remove ruts > 100 mm.

  2. Roll out geotextile: Place directly on the prepared area without tension.

  3. Overlap or weld: Minimum 300 mm overlap (500 mm for soft subgrades); welding recommended for grades ≥ 200 g/m².

  4. Repair damages: Patch with same grade geotextile overlapping ≥ 500 mm.

  5. Place fill: Back-dump aggregate onto the fabric; avoid direct truck traffic.

  6. Spread and compact: Use tracked equipment and vibratory rollers; target rut depth ≤ 30 mm.

  7. Re-grade if required: Fill ruts with fresh aggregate only.
