3.5 oz Non Woven Filter Fabric Applications
The 3.5 oz non woven filter fabric is a lightweight, high-flow material used for effective drainage, filtration, and soil stabilization. It provides reliable performance across various project types, making it a popular choice for erosion control and ground reinforcement.
- Bank stabilization: Supports embankments and prevents soil displacement
- Erosion and sediment control: Holds soil in place on slopes and drainage paths
- Construction underlayment: Reinforces soil beneath roads, driveways, and job sites
- Filtration and drainage: Filters out sediment while allowing water to flow through
- Soil stabilization: Improves structure in areas with weak or sloped soils
3.5 oz Non Woven Filter Fabric Installation Instructions
Follow these general guidelines to install 3.5 oz non woven filter fabric. Always refer to project-specific plans when available, as site conditions may require adjustments.
- Prepare the site: Clear the installation area of debris, rocks, stumps, and any sharp objects that may damage the fabric.
- Level the ground: Smooth and grade the surface to create an even base for fabric placement.
- Lay out the fabric: Position the rolls according to your project plan. Overlap fabric edges by 12 to 18 inches to ensure full coverage.
- Secure the fabric: Use landscape staples or pins to anchor the fabric in place, especially along overlaps and edges.
- Backfill: Cover the fabric with a minimum of 6 inches of backfill material to protect it and maintain performance.
