Stability That Stays Put: Geopier SRT System for Slope Protection
by Bruce Bush, on March 19, 2026
When a slope fails—whether beside a highway, along a railway corridor, or at the edge of critical infrastructure—the consequences can be costly, disruptive, and even dangerous. While traditional fixes may require extensive earthwork and the use of retaining walls or soil nailing, the Geopier® SRT® system is an efficient, cost-effective, and minimally disruptive solution for a variety of complex slope stabilization challenges.
Construction on Sloped Sites
Geopier’s SRT® system is designed to stabilize slopes where soil conditions consist of an upper zone of weathered, loose, soft or disturbed soil over a stable zone of soil or soft rock. It’s ideal for:
- New slope reinforcement and shallow slide remediation up to 15 feet deep.
- Projects demanding minimal earthwork and fast installation.
- Projects driven by cost and timing.
- Constrained sites.
How Does the Geopier SRT® System Work?
Rather than relying on more traditional methods, the Geopier® SRT® system uses patented Plate Pile™ elements—long, narrow steel plates—that are driven deep into the slope. Here’s how it works:
- Plate Pile™ elements are driven through unstable soil into a competent layer beneath the slide zone.
- Because these plates are closely spaced and patterned, they act as a continuous line of resistance with the soil mass.
- The system leverages soil arching and internal force transfer to create a reinforcement grid that stabilizes the slope with far less earthwork and disruption than alternative methods.
How Does Geopier's SRT® System Offer Better Slope Protection?
For many clients, the Geopier® SRT® system is the preferred approach on sloped site construction projects where cost, speed, and ease of access matter most. Here’s how it can get you out of tight spots—literally and figuratively:
- Cost-efficient—providing significant savings compared to cut-and-replace, soil nail walls, or structural retaining walls.
- Minimal site disturbance—no need for extensive grading, spoil removal, or permanent drilling rigs; particularly valuable in locations with constrained rights-of-way, limited access, or sensitive operations nearby (e.g. highways, rail lines, utility corridors).
- Quick installation—small crews and compact equipment can install hundreds of elements quickly, keeping your construction project on schedule.
- Vegetation-friendly finish—finished slopes can be re-vegetated quickly and naturally.
Geopier SRT® System Case Studies
OH-30W to OH-23S Interchange
ODOT faced recurring slope failures along the OH‑30W to OH‑23S interchange embankments, with multiple slides and challenging clay‑over‑silt subsurface conditions. Geopier’s SRT® Plate Pile™ system provided a fast, low‑impact stabilization method—766 piles installed directly on the embankment without major grading, lane closures, or heavy equipment needs. The result was a rapid, efficient fix that minimized disruption at a busy transportation corridor.

New Madrid Power Plant
A levee surrounding the New Madrid Power Plant’s raw‑water pond had suffered repeated shallow slope failures driven by rapid drawdown and saturated clay soils. Traditional earthwork repairs weren’t holding—but the Geopier SRT® system offered a long‑term, economical stabilization method ideal for the soft, groundwater‑impacted conditions. The Plate Pile™ solution strengthened a 1,000‑ft levee stretch while keeping the embankment functional.
