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.


  • 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.


  • 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.



  • 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

Coir Fibre (Fibrax) Blanket for Hydroseeding/ Hidrosemeadura/ Hidrossemeadura

Hydroseeding/ Hidrosemeadura is a process where you can get the 100% success ability with using Biomanta Fibra de coco. Bio Manta will help to protect the seeds while working as a supportive medium to grow. It Provides necessary needs such as, moisture, nutrients and etc. Moreover, this Fibrax/ Fiber Mat can be used with vetiver grass (capim vetiver) for faster vegetation generation process. Also, Plantula growing in Bio Manta will help to improve the soil stabilization and it will reduce the erosion and soil loss.

Coir Fibre (Fibrax) Blanket for Bioengineering / Bioengenharia

Biomantas Antierosivas, Capim vetiver, Water flow controlling mining mat (Erosoes em areas de mineracao), Supressao Vegetal techniques are the main options which is used to maintain the erosion recovery and control.

Soil Stabilization

Soil Stabilization technology is a common practice in Road and slope Stabilization to improve soil strength by modifying the engineering properties of the soil itself. Our coir blanket/Geotextile is a geo fabric material and our Soil Stabilization mat has been used to strengthen the soil in the respective area. It is effective, fast, and requires minimum skill during the installation process. Today, the role of Soil Stabilizer is essential in construction industry because it has helped many organizations in maintaining and improving their infrastructure and Road Stabilization.

This Nonwoven-Geotextile solution increases soil shear strength by providing strength to soil quality and structural stability. As Cushion or Protection, Non-Woven Fabric allows permanent protection during installation and after completion of construction compared to coir logs and coir geo textiles.
