Solutions for Every Structure
Tunnel Grouting
Tunnel grouting is a critical geotechnical process used to stabilize ground, control water ingress, and strengthen surrounding soil or rock during tunnel construction. By injecting specialized grouts into voids, fissures, and weak zones, tunnel grouting improves load-bearing capacity and minimizes ground settlement. This process ensures safer excavation, enhances structural integrity, and supports long-term tunnel performance in challenging subsurface conditions.
Tunnel Lining - Mortar ( Geoconstech based) and Shotcreting
Tunnel lining using mortar and shotcreting provides immediate structural support and surface stabilization during tunnel excavation. Shotcrete is pneumatically applied to freshly excavated tunnel surfaces, forming a strong protective layer that bonds with rock and concrete. This method prevents loose material fall, enhances safety for workers, and creates a stable base for permanent lining systems in underground construction projects.
Tunnel Retrofitting And Rehabilitation
Tunnel retrofitting and rehabilitation involve restoring and upgrading existing tunnel structures to meet current safety, durability, and performance standards. Over time, tunnels may suffer from structural distress, leakage, corrosion, or material degradation. Retrofitting solutions strengthen weakened sections, repair damaged linings, and improve load-bearing capacity, ensuring tunnels continue to operate safely under increasing traffic and environmental demands.
Tunnel Water Ingress Control
Tunnel water ingress control focuses on preventing and managing groundwater seepage that can compromise tunnel safety and durability. Water entering through cracks, joints, or surrounding ground can cause structural damage, corrosion, and operational hazards. Effective ingress control systems seal leakage paths and protect tunnel interiors from continuous moisture exposure.
Tunnel Bolting
Tunnel bolting is a vital ground support technique used to stabilize rock and soil during tunnel excavation. Rock bolts are installed into surrounding ground to bind loose strata together, improving overall rock mass strength. This method prevents collapse, controls deformation, and ensures worker safety during construction, especially in weak, fractured, or jointed geological conditions commonly encountered in underground projects.
Preexcavation & Post excavation Grouting
Tunnel pre-excavation and post-excavation grouting are specialized techniques used to strengthen ground and control water ingress before and after tunnel excavation. Pre-excavation grouting improves ground conditions ahead of the tunnel face, reducing permeability and stabilizing weak zones. This proactive approach ensures safer excavation and minimizes risks associated with groundwater pressure and ground settlement.
