Soil Bioengineering is an established method of stabilizing or protecting eroded soils. It is unique in plants, such as roots and stems, and is used as the main structural components to reinforce the soil and provide protection to water sources. These imbedded plant materials act as:

soil reinforcements

barriers to earth movement

hydraulic drains

moisture wicks

Structures are created to provide immediate mechanical stability while establishing a vigorous root zone structure within the eroded soil. These living structures have an inherent ability to become stronger with time and self-repair water edges, provide habitats for aquatic and terrestrial wildlife and filter runoff water.

Growth of the bioengineering materials forms a healthy, natural groundcover of native plants, while creating microclimatic conditions favorable to the establishment of other native plant species and wildlife habitat.

A variety of soil bioengineering methods can be applied for stabilizing areas of surface erosion or shallow landslides. Different methods, or combination of methods, can be used to/on:

cut and fill slopes along roadways

landfill covers

spoil banks

wildlife habitat

landscape restoration

stream banks

Our Coir fiber soil bioengineering products play a significant role in today’s soil bioengineering techniques. They strongly support the reinforcement of soil, as well as provide mulch and improve soil conditions.

Soil Bioengineering Products:

E-Coir Green Log

E-Coir Green Log is made from machine-spun coir twine stuffed under pressure with mattress grade coir fiber to specified density. High density E-Coir Green Log has excellent structural stability and it also resists the force of the water flow while establishing natural vegetation. These logs can be used in low gradient areas in stream, lake, shoreline protection and slope stabilizations. It helps to dissipate the impact of flowing water and stop sediment. E-Coir Green Log fosters plant growth among the coir fiber and eventually decays, while becoming a natural part of the bio-engineered site over 5 or more years. It also provides aesthetic value to the surrounding environment.

The root system created by the vegetation within the riparian buffer prevents future erosion in the wetland areas due to high water flows.

E-Coir Green Logs can be supplied as a circular coir log or square log. In addition, our E-Coir Green Logs are available in planting holes and impregnated with coconut shell activated carbon.

E-Coir Weed Mat

E-Coir Weed mat is a needle punched coir matrix that bonded with natural latex binder. It is 100% biodegradable mat which can be used to stop erosion and control weeds. The weed mat completely breaks down within 15-18 months and provides mulch to the soil. The porous structure of the mat helps water, fertilizer and air to penetrate through the coir fiber. It doesnot hold the heat and helps roots and soil to breath. E-Coir Weed mats are available in circular, square and roll forms. Each weed mat form has an appropriate cut, a middle hole and a split for easy installation.

E-Coir Sand Bag

Coastal Erosion is a natural process of the wearing away of land or the removal of beach or dune sediments by wave action, tidal currents, wave currents or drainage. It is a serious problem in many coastal areas across the globe. Strong waves have enough energy to carry sand away from the beach. After the waves break, this results in erosion of the recreational beach. Establishing a strategic and comprehensive framework to protect and conserve the coastal marine ecosystem is very important.

Our E-Coir Sandbag is made from 100% clean coir fiber with, internally, coir matrix bonded with natural latex binder and, externally, coir fiber encased in a coir mesh geotextile layer. E-Coir Sandbags can be placed on a level contour on severely eroded coastal lines to protect them from strong waves. Sandbags last over 5-6 years and they have natural UV resistant properties. When sand layers deposit on the bags, the bags become more stable and heavier which prevents sand erosion and helps to re-establish the coastal ecosystem.
