Expansion Joint Sealing

Expansion joints are critical components in concrete infrastructure, allowing structures to accommodate thermal expansion, settling, and seismic movement while maintaining structural integrity. Our expansion joint sealing service provides specialized solutions for dams, bridges, buildings, and other critical infrastructure.

Critical Infrastructure Applications

Our expansion joint sealing expertise covers:

• Hydroelectric Dams: Sealing expansion joints in dam structures and penstock galleries
• Bridge Infrastructure: Waterproofing bridge deck and structural expansion joints
• Industrial Facilities: Sealing joints in manufacturing and processing plants
• Commercial Buildings: Protecting building expansion joints from water infiltration

Proven Track Record

Our team has successfully sealed critical expansion joints in major infrastructure projects, including the S2-S3 expansion joint at HE Đerdap 1 hydroelectric plant. This project demonstrated our ability to seal leaking joints without shutting down operations, maintaining power generation while providing permanent waterproofing.

Advanced Sealing Technology

We use flexible, high-performance sealants that maintain elasticity under extreme conditions:

• Temperature variations from -40°C to +100°C
• Continuous underwater exposure
• High hydrostatic pressure
• Structural movement and vibration

No-Shutdown Solutions

Our injection techniques allow expansion joint repairs to be performed without shutting down critical operations, minimizing economic impact while ensuring structural protection.
