Methods
A commitment to the earth’s environment through innovative materials and excellent technical support has earned BonTerra a world-class recognition for leadership. Not all potential erosion is the same.
Soil type, length of slope, moisture availability, fertility, and degree of the slope are only a few of the variables to consider when planning erosion prevention measures. BonTerra provides a variety of blanket types and application methods for different situations.


Slopes
- Grade and smooth slope. Apply fertilizer and seed prior to installing blankets.
- Anchor blankets at top of the slope. Use anchoring method „A“ for 4:1 slopes, „B“ for 3:1 slopes and „C“ for 2:1 and steeper slopes
- Unroll blankets in direction of water flow. Place blankets loosely and in full contact with the soil.
- Overlap blanket edges approximately 5 cm (2″) and staple. Note: install blankets so edge overlaps are shingled away from prevailing wind.
- Overlap blanket ends 15cm (6″), upper blanket over lower blanket, and staple using five staples (anchor „A“)
- Cut excess blanket with scissors and anchor at end of the slope. Use anchoring method „A“ for 4:1 slopes and „B“ for slopes 3:1 or steeper.

Shorelines
- Grade and smooth channel. Apply fertilizer and seed prior to installing blankets.
- Install blankets during the lowest possible water level.
- Install blankets horizontally along shoreline if one width is sufficient.
- Secure top edge of the blanket („B“).
- Overlap blanket ends and staple („A“).
- Anchor bottom edge of the blanket („B“).
- For shorelines steeper than 3:1 slope, install blankets vertically using slope instructions.

Process

Channels
- Grade and smooth channel. Apply fertilizer and seed prior to installing blankets.
- Anchor blankets at top of channel („B“). Backfill with check slot material. For culvert outfalls, place blanket at least 30 cm (12″) upstream from pipe opening.
- Install a blanket in the centre of the channel, in the direction of water flow.
- Additional blankets are installed at the edges of this center blanket.
- Construct check slots with soil, gravel, or stone, in the middle (15 m / 45 ft.) and end of each blanket.
- Overlap side channel blanket edges 10 cm (4″) over the center channel blanket and staple.
- Anchor the top edge of side channel blankets („B“).
- Anchor the terminal ends of blankets in a check slot
