Tunneling - Injection

Injection and chemical grouting in tunnel applications are key techniques for controlling water ingress and improving ground stability. Pre-injection is used ahead of excavation to seal water-bearing zones and strengthen weak ground, while post-injection addresses leaks and voids after excavation. Using a range of chemical grouts, these methods offer fast reaction times, strong adhesion, and long-term durability, ensuring safe and efficient tunneling in challenging conditions.
