Slope/Embankment Stabilization and Revegetation with ProGanics DUAL and Presto GEOWEB

UPRR Big Spring Slope Protection


  Engineer: Profile Products/Presto

  Contractor: LRL Construction

   Date: April 2022


Project Goals and Specs:

Stabilize and revegetate the steep slope/embankment with poor soil conditions to achieve sustainable, long term results.


Problem:

The Project was located on the east side of train tracks. Prior to the GEOWEB installation, erosion and sheet flow were causing soil to be washed into ballast/train tracks. Once the natural hillside was stabilized, a soil test was completed to assess the organic conditions of the on-site material. Organic content in the soils were very low and an erosion control solution would be required to protect the slope during/post construction.


Slope in Big Spring, TX
Site Conditions:

In situ material consisted of hard clays with little to no organic matter. The 2:1 slope was not stabilized and showed significant signs of reeling and erosion.


Identified Issues and Constraints:

The project called for 6” of imported fill to be laid on the 2:1 slope. The exposed soil was subject to washing out upon the next rain fall event. The goal was to contain the imported fill, while mitigating soil loss until adequate vegetation was achieved.


ProGanics hydraulically applied to slope for erosion control
Solutions / Final Application / Results:

In an effort to confine the imported soil, 6” GEOWEB was stretched downslope, on top of a nonwoven fabric. The nonwoven fabric served to improve drainage and separation of materials. Next, ProGanics DUAL was hydraulicaly applied as a single step solution to optimize soil conditions, while providing high performance erosion control and protection from near storm events.

Optimization Highlights:

Minimal impact to local site conditions and cost savings for massive areal coverage.

No one can afford to have their revegetation projects fail. The most common reason revegetation projects fail is poor soils that lack the components necessary to adequately promote seed germination and sustainable plant growth.
