Envirolok
Key Benefits
The Envirolok System is a patent pending erosion control and slope
stabilization system that creates vegetated walls in combination with
deep-rooted native plants. The Envirolok vegetated retaining walls by Agrecol®
are strong, environmentally-friendly alternatives to conventional erosion
control systems.
Use Envirolok Retaining
Walls For:
 | Erosion Control |
| Shoreline Stabilization |
| Stormwater Management |
| Stream Restorations |
| Residential lakeshore preservation and remediation |
| Landscaping enhancements |
| Creating naturalized buffers along tributaries |
The Science of Erosion Control
Agrecol defines temporary erosion control as the ability to hold soil in
place long enough to establish vegetation with an extensive root system, which
then provides long-term erosion control.
| Environmentally-friendly bags; native plant roots grow
into and through them |
| Soil bags are vegetated for a long-term ecological
solution |

How The Envirolok Vegetated Retaining
Wall System Works:
The ecologically-advanced Envirolok System provides
long-term erosion control in three important steps:
- Envirolok sand/soil bags are woven into a wall unit with a unique weaving
component and technique and a locking spike to create immediate soil
confinement. Weaving the wall makes it into one strong unit instead of
individual components. Patent pending.
- The face of the sand/soil bags are planted with Agrecol native seed,
plants and sod, which develop extensive root systems, growing through the
bags. The woven wall and growing natives hold the structure in place while
the native plant roots grow deeper and stronger, up to 20 feet or more.
Depending on local conditions, natives may take from six months to two years
to develop the root system necessary to insure long-term erosion control
success.
- Mature natives, with their powerful root structure going 20 or more feet
into the earth, lock the wall into place, even growing into the soil below and
adjacent to the wall. This provides an ecologically sound and beautiful
vegetated erosion control system with permanent structural strength.
System Benefits
| Deep-rooted perennial vegetation locks, renews and
improves the structure year after year |
| Does not interfere with hydrological processes |
| Provides habitat, safe for amphibious species |
| Retains oxygen and moisture |
| Absorbs sound |
| Moves with freeze / thaw cycles |
| Weeping/hydraulic piping is minimal in comparison to
block or stone wall erosion control systems |
NOTE: Advice from an engineer is recommended when building walls more than 4’
in height, or when site conditions include unusual erosion or weak soil
conditions.
NOTE: Do not burn native vegetation growing on the Envirolok system.
