Slope Protection Works for the Design & Construction of Yiti Internal Roads at Al Husn
Stabilizing Urban Slopes to Support Safe and Sustainable Road Development
The development of internal roads at Al Husn, Yiti required extensive slope protection works due to the presence of cut slopes formed during excavation. These slopes exhibited a combination of loose surface material, fractured rock zones, and varying stability conditions across a relatively compact urban footprint.
TEICO delivered a comprehensive slope protection solution, combining surface preparation, containment systems, structural reinforcement, and rockfall interception to ensure long-term slope performance and road safety.
Project Overview
The project involved stabilizing multiple slope sections created during the construction of internal roads within the Al Husn development. Due to variable rock quality and slope geometry, a range of protection systems were applied to address site-specific stability requirements.
Project Details
- Project: Design & Construction of Yiti Internal Roads at Al Husn
- Location: Al Husn, Yiti, Muscat Governorate, Sultanate of Oman
- Client: Muscat Municipality – Sultanate of Oman
- Scope: Slope Protection Works
- Quantities Delivered:
- 18,184 m² Cleaning and Scaling
- 7,949 m² Simple Wire Mesh
- 8,714 m² Reinforced Wire Mesh (6 × 6 m)
- 783 m² Reinforced Wire Mesh (3 × 3 m)
- 162 m² Cable Netting
- 628 lin.m Rock Dowels
- 320 m² Rockfall Barrier – 1,500 kJ
- 576 m² Shotcrete
Challenges Identified
- Cut Slopes with Loose Surface MaterialExcavation exposed weathered rock and soil requiring extensive cleaning and scaling.
- Highly Variable Rock ConditionsStability requirements varied significantly across short distances, necessitating multiple protection systems.
- Localized Rockfall Risk Near Internal RoadsCertain sections posed a direct risk to road users and adjacent infrastructure.
- Limited Working Space in an Urban SettingWorks had to be executed safely and efficiently within a constrained development area.
Solution Implemented:
1. Cleaning and Scaling Operations
- •Executed 18,184 m² of cleaning and scaling to remove loose rock and unstable material prior to protection works.
2. Wire Mesh Surface Containment
- •Installed simple wire mesh in low-risk areas to control minor raveling.
- •Applied reinforced wire mesh (6 × 6 m and 3 × 3 m) in higher-risk zones to provide stronger surface confinement.
3. Cable Netting for Enhanced Containment
- •Installed 162 m² of cable netting where larger fractured blocks required higher load capacity.
4. Rock Dowels for Structural Reinforcement
- •Installed 628 linear meters of rock dowels to consolidate fractured zones and improve slope integrity.
5. Rockfall Barrier Installation
- •Installed 320 m² of 1,500 kJ rockfall barrier to intercept falling rocks in critical hazard zones.
6. Shotcrete Application
- •Applied 576 m² of shotcrete to stabilize highly weathered surfaces and protect against erosion.
Project Outcomes: Slope Protection Works for the Design & Construction of Yiti Internal Roads at Al Husn
Comprehensive Stabilization Across Variable Slopes
The combined use of scaling, mesh systems, dowels, shotcrete, and rockfall barriers delivered consistent stability across diverse slope conditions.
Improved Safety for Internal Road Users
Rockfall and surface instability risks were significantly reduced, ensuring safe daily use of the internal road network.
Tailored Engineering Solutions for Urban Terrain
Each slope section received protection aligned with its specific geotechnical requirements, optimizing performance and material use.
Durable, Low-Maintenance Slope Systems
The installed systems provide long-term resilience with minimal intervention, supporting sustainable urban infrastructure.
Enhanced Reliability of the Al Husn Road Network
Stabilized slopes contribute to uninterrupted access and long-term serviceability of the internal roads.
