Coir logs provide biodegradable soil erosion control on slopes, riverbanks, and shorelines, building up a compromised area and stabilizing it so new vegetation can regrow. Made from biodegradable coir twine netting that surrounds a mix of mattress coconut coir, erosion control logs typically have a lifespan of 2 to 5 years until they naturally degrade. Erosion control logs are safe for existing wildlife in the surrounding environment. Coconut coir fiber logs return nutrients to the soil, naturally break down, and don't require removal after installation. See our coir logs specifications for more information!
Stabilizing Soil with Erosion Control Coir Fiber Rolls
Coir Logs for Soil Erosion Control
What are Coir Logs?
Coir logs are an ecofriendly, biodegradable choice for Sediment Control and slope stabilization. Municipalities often face the challenge of protecting water resources, parklands, and public infrastructure from sediment damage. Coir logs provide a cost-effective method that aligns with environmental conservation goals.
Soil erosion control affects many different municipal departments. From road infrastructure to public parks to water management, controlling sediment means solving far-reaching problems. Soil erosion control can be a long process, but the fiber rolls ability to naturally degrade allows the project to have minimal maintenance.
Coir Log Features and Benefits:
- Naturally biodegradable coir fibers
- Have a diameter of 12, 16, or 20 inches
- Increased strength from dense construction
- Easy to install and can be joined together
- Lifespan of 2 to 5 years
- Builds into existing contours
Coir Logs Specifications
Standard Density Coir Logs
These are the industry standard for use in average conditions and at a price point that's budget friendly. 100% biodegradable, the Standard Density Coir Logs are made of 100% coir encased in a 2" x 2" coir netting. Coir Logs promote a natural solution to erosion control and slope stabilization, while creating an environment that supports vegetative growth for long term erosion control as the coir eventually biodegrades.
| Diameter | Length | Weight | Density | Wave Height |
|---|---|---|---|---|
| 12" | 10' | 5.0 lbs/ft | 7.0 lbs/ft³ | 12' |
| 16" | 10' | 9.0 lbs/ft | 7.0 lbs/ft³ | 20' |
| 20" | 10' | 15 lbs/ft | 7.0 lbs/ft³ | 30' |
High Density Coir Logs
High density coir logs are recommended for use on rigorous terrain, areas exposed to high flow or harsh environmental conditions. They are also a reliable erosion control solution for streambanks and lakeshores, as well as for slope stabilization. Manufactured with 100% coir fibers encased in a rhombic coir netting, these high-density coir logs are known for solid performance in the most demanding situations and for the longest duration in the field.
| Diameter | Length | Weight | Density | Wave Height |
|---|---|---|---|---|
| 12" | 10' | 7.0 lbs/ft | 9.0 lbs/ft³ | 12' |
| 16" | 10' | 12.5 lbs/ft | 9.0 lbs/ft³ | 20' |
| 20" | 10' | 19.5 lbs/ft | 9.0 lbs/ft³ | 30' |

Installing Coir Logs — Tools, Anchors, and Accessories
Proper installation ensures coir logs stay in place and perform as intended. With the right preparation and tools, these erosion control logs can be anchored securely for long-term effectiveness. Start by clearing the site of debris, rocks, and branches. Dig a shallow trench along the installation path, place the logs tightly inside, and backfill with soil to hold them firmly in position. Join adjacent logs end to end using coir twine or biodegradable ties to ensure continuous coverage. Anchor the logs using biodegradable stakes or heavy-duty staples, adjusting the spacing based on slope grade, soil conditions, and log diameter. Common tools used during installation include:
- Biodegradable landscape stakes
- Biodegradable net peg
- Line driver
- Staple driver
When installing erosion control rolls, it's recommended that vegetation be planted within the structure of the logs to increase soil and slope stabilization. Once the log has biodegraded, the plants will remain, creating a natural erosion control barrier.
| Stream | Flow | Diameter | Anchor Height | Anchor Spacing |
|---|---|---|---|---|
| Large | Heavy | 20" | 4 foot minimum | Every 2 feet |
| Large | Moderate | 16" | 3 foot minimum | Every 2.5 feet |
| Medium | Moderate | 12" | 30 inch minimum | Every 3 feet |
| Medium | Moderate | 12" | 30 inch minimum | Every 3 feet |

Coir Log Applications
Coir logs are used across a wide range of environmental and infrastructure projects, from slope stabilization and wetland restoration to shoreline protection and construction site compliance. Their biodegradable coconut fiber structure offers long-term erosion control while naturally breaking down into the soil, eliminating the need for removal and reducing labor costs. This hands-off maintenance approach makes coir logs a cost-effective choice for municipalities and environmental engineers seeking low-impact solutions.
Because of coconut coir’s slow decomposition rate and high permeability to air and water, these logs are ideal for projects requiring vegetation regrowth and soil stabilization. They’re frequently installed along dams, railway embankments, stormwater retention zones, and in habitat restoration projects where durability and environmental safety are critical. Actual product lifespan varies depending on environmental conditions but typically ranges from two to five years, during which the logs continue to support sediment control and plant development without harming native ecosystems.
Other coir log applications include:
- Dam construction
- Shoreline protection
- Railway embankments
- Wetland restoration
