4.5 oz. Non Woven Geotextile Installation
These general guidelines apply to installing 4.5 oz non woven geotextile fabric for drainage. Always follow project-specific plans if available.
Before you begin, make sure you've selected the correct fabric weight and roll size. For help choosing the right non woven geotextile or other types of geotextile, contact our product specialists.
- 1. Prepare the area: Clear all debris, sharp objects, or obstructions. Level the ground to ensure the fabric lies flat.
- 2. Lay the fabric: Roll out the geotextile according to your project plan. Overlap edges by 12–18 inches.
- 3. Secure the fabric: Use landscape staples or stakes to pin the fabric in place, especially along overlaps.
- 4. Backfill: Cover the fabric with at least 6 inches of material. Use more if soil is loose or unstable.
