As a trusted supply partner, we delivered a comprehensive range of construction chemical solutions to ensure the structural durability and long-term performance of the Beijing Underpass project:

• Sealant – Joint sealing and waterproofing to prevent water ingress
• Admixture – Enhanced workability, strength, and durability of the concrete mix
• Curing Compound – Ensured proper hydration and crack-free curing of concrete surfaces
• Grout – High-strength, non-shrink grout for precision anchoring and load transfer at critical junctions
• Shotcrete – Rapid, high-strength sprayed concrete application for tunnel lining and slope/wall stabilization in the underpass structure
• Epoxy Adhesive – High-bond-strength adhesive for structural bonding of concrete-to-concrete and concrete-to-steel interfaces
• Epoxy Bonding (Bonding Agent) – Ensures monolithic bond between old and new concrete layers during repair or extension works
• Concrete Accelerator (for Shotcrete) – Speeds up initial and final setting time of shotcrete for faster tunnel support and reduced rebound loss

Together, these solutions contributed to a durable, watertight underpass built to withstand heavy traffic loads and long-term environmental exposure.
