Slope Protection Works for the Upgradation of Birkat Al Mouz - Sayq Road

Stabilizing High-Elevation Slopes Along a Critical Mountain Route

The upgradation of the Birkat Al Mouz - Sayq Road required specialized slope protection works across steep, high-altitude terrain. The route passes through rugged mountain sections where cut slopes are exposed to weathering, rockfall risk, and long-term instability.

TEICO was engaged to deliver slope protection solutions using advanced access methods and controlled installation techniques to ensure safety, durability, and uninterrupted road functionality.

Project Overview

The project focused on protecting steep cut slopes along the Birkat Al Mouz - Sayq corridor, where conventional access methods were not feasible. Slope protection works were executed using basket-supported drilling, saddle systems, and specialized climbers to safely stabilize exposed rock faces.

Project Details

Project: Upgradation of Birkat Al Mouz - Sayq Road
Location: Birkat Al Mouz - Sayq Road, Sultanate of Oman
Client: Sultanate of Oman - Ministry of Transport & Communications
Scope: Slope Protection
Quantities Executed:
- 61,000 sqm of Reinforced Mesh
- 2,600 m of Rock Dowels
- 2,500 m of Rock Anchors

Challenges Identified

Extensive Weathered and Fractured Rock FacesLarge sections of the slope consisted of highly weathered rock with open joints and loosened surface blocks, increasing the likelihood of progressive raveling and rockfall.
Deep-Seated Instability ZonesCertain slope sections showed signs of deeper instability, requiring reinforcement beyond surface protection to ensure long-term performance.
High and Continuous Cut SlopesThe road alignment created long, uninterrupted rock faces where instability could propagate across wide areas if left untreated.
Exposure to Harsh Environmental ConditionsTemperature variation, wind exposure, and rainfall events accelerated surface degradation and erosion along the slope faces.

Solution Implemented:

1. Surface Containment with Reinforced Mesh

•Installed 61,000 m² of reinforced wire mesh to provide continuous surface confinement.
•The mesh system restrained loose rock fragments, prevented raveling, and maintained close contact with the slope profile.

2. Rock Dowel Installation for Local Consolidation

•Installed 2,600 m of rock dowels to stabilize fractured and weathered zones.
•Dowels tied unstable surface layers back into more competent rock, reducing localized movement.

3. Rock Anchors for Global Stability

•Installed 2,500 m of rock anchors to address deeper instability and improve overall slope integrity.
•Anchors transferred loads into stable rock mass, enhancing long-term slope performance.

4. Integrated Stabilization Approach

•The combined use of mesh, dowels, and anchors created a unified system where surface containment and structural reinforcement work together to control both shallow and deep-seated instability mechanisms.
