Problem: Repair structural concrete during elevated track downtime

Solution: ChemCo injection resins that cure quickly

• Re-opened elevated track early am after midnight closure
• Grout, Standard reaches 5000 psi compressive in 3 hours
• ChemCo injection resins do not pass through crystalline gel stages
• Track vibration won’t affect final cure
• Grout, Standard for bearing pad restoration
• Grout, Large Void for segmental bonding (need long potlife)
