PROJECT DETAILS:
Project Name: Pipeline Slope Stability
Location: Versailles, Illinois
Date of Installation: June 2020
Contractor: Midwest Services Group
Salesperson: Ed Nelson
Application/Solutions: Propex's erosion control solutions combined with Profile Products' vegetative solutions for a streambank and slope stabilization solution.

THE CHALLENGE:
The contractor was faced with a steep slope along a natural streambank that failed. The slope was eroding and contaminating the stream with sediment. This slope was also in a pipeline’s right-of-way (ROW) area. To ensure the safety of the pipeline and surrounding property, the slope needed a long-term, high-performance stabilization solution to correct the failing slope and prevent any issues in the future.

THE SOLUTION:
Two of Solmax’s (formerly Propex) products were recommended for this project. SCOURLOK was utilized to stabilize the toe of the slope at the creek bottom. To create a stable slope, ARMORMAX Engineered Earth Armoring System™ was utilized by combining High Performance Turf Reinforcement Mats (HPTRMs) and Engineered Earth Anchors™ (EEA) that work together to lock soil in place and protect against hydraulic stresses.

Next, two of Profile Products’ products were recommended. To improve the likelihood of successful vegetation, ProGanics Biotic Soil Media was sprayed on top of the ARMORMAX and Flexterra flexible growth medium was the final “glue” to stabilize the slope surface, supply moisture support for the vegetation establishment, and ensure the seeding remained in place until root establishment is maintained.

PRODUCTS USED:

• PROPEX® Armormax® Engineered Earth Armoring System™
• PROPEX® Scourlok® Engineered Bank Stabilization System
• ProGanics® Biotic Soil Media™
• Flexterra® HP-FGM®

THE RESULTS:
After ProGanics & Flexterra installation.

One year later the slope is fully vegetated and looks great.
