• Matsalolin Anchor: As mentioned for slopes, trenches are the most secure method for terminating edges. After placing the geotextile edge in the trench, the backfill material must be compacted thoroughly to create a permanent lock.
• Securing Pins or Staples: For perimeter edges or along long overlaps, U-shaped steel pins or staples can be used. These should be spaced at 0.3–1 meter (1–3 foot) intervals. This method is common for erosion control applications but provides less long-term security than a trench.
