Installation guidelines
- Prepare the site by clearing debris and grading the slope as needed.
- Dig a trench at the top of the slope to anchor the mat securely.
- Unroll the mat downslope, ensuring it aligns with the direction of water flow.
- Overlap adjacent mats by at least 6 inches to prevent gaps.
- Secure the mat using U-shaped staples or wooden stakes at regular intervals.
- Backfill the trench and compact the soil to anchor the mat firmly.
