Silo 7 Retrofitting- Cement of Sibline

Client: Cement of Sibline s.a.l

Consultant: Nabil Hannawi

Contract: 500K

The existing silo exhibited advanced reinforcement corrosion, significant concrete degradation, and reduced load-bearing capacity due to prolonged exposure to aggressive environmental conditions. A

two-phase rehabilitation strategy was implemented to address these deficiencies while ensuring structural continuity and long-term performance.

A two-phase structural rehabilitation project aimed at halting active corrosion and restoring structural load-bearing capacity. The intervention ensures long-term durability and prevents critical structural failure through a full concrete jacketing system

.

• Hidden Structural Deficiencies - Previously undetected reinforcement deterioration revealed during demolition, resulting insignificant increase in repair scope
• Inadequate Reinforcement - Anchorage Existing steel exhibited insufficient bond and anchorage capacity, requiring redesign ofload transfer mechanism
• Complex Vertical Execution - Constraints Work executed on a 27 m high cylindrical structure requiring controlled sequencing,access management, and safety compliance
