APPLICATION:
Overwinter Protection and Vegetation Establishment on Constructed Streambanks
SITE DESCRIPTION:
- Standard cool season annual/perennial grass and legume mix
- Silty Clay Loam soil
- Approximate 6ft wide stream channel bottom (left unprotected for natural substrate)
- Stream channel bottom gradient <1%
- Variable gradient sideslopes (protected with ShearForce10 ECTRM)
- Drainage from 120 acres of reclaimed mineland
- Over 30 inches of rainfall from Oct 25, 2018 through April 30, 2019

Objective
Test application for the InstaTurf® ShearForce™ 10 ECTRM at protecting the highly erodible banks of a constructed stream channel through reclaimed mineland over the winter months, while establishing permanently reinforced vegetation
Extreme Conditions
Unusually heavy rains throughout the fall, winter, and spring months flooded the stream channel on numerous occasions.
The two inch rainfall that occurred one week after installation severely damaged coconut erosion control blankets installed on other sections of the stream channel and initiated significant bank erosion.
Many banks along the stream channel where coconut blankets had been installed were on the verge of collapsing by early spring due to severe undercutting.
Results
ShearForce10 effectively armored the streambanks through all flood events, sustaining a good stand of vegetation by April 30.
The ShearForce10’s simulated turf structure captured sediment in stream flow which further enhanced the mats’ erosion control capabilities by locking down material between anchor points.
InstaTurf ShearForce10 successfully stabilized the banks of the stream through the fall, winter and spring months, with vegetation now permanently reinforced against future flood events.

Relevant Case Studies
Chesterfield Residential Pondbank Stabilization
Discover how the Chesterfield Residential Pondbank Stabilization project transformed a struggling dam into a resilient, eco-friendly solution. Faced with the challenge of transporting heavy rock riprap, DJM Ecological proposed the innovative InstaTurf® ShearForce™10 hybrid turf instant armor mat. This alternative not only saved costs by 50% but also ensured quick installation with minimal disruption to the surrounding environment. With native vegetation thriving and long-term erosion resistance achieved, this project exemplifies sustainable landscaping.
