Project Management Solutions for Sustainable and Durable Tunneling

Tunneling projects often require complex solutions to address persistent issues such as dust suppression, water ingress, and material stability. While conventional methods provide some relief, they can be costly, inefficient, and fall short of delivering long-term results. Challenges such as dust and contaminants jeopardize air quality and worker health, while water ingress weakens tunnel infrastructure by causing spalling and flaking. Stabilizing loose materials on slopes can add significant costs and delays, and often highlight the need for a more efficient and durable approach.

Addressing these issues with an AggreBind solution; a comprehensive approach to solving the specific demands of tunnel construction, can transform project outcomes and budgets. With its patented technology, AggreBind uses both topical treatments to ensure site safety and AggreCrete cement additive for enhancing the durability and flexibility of concrete structures within tunnel projects.

Topical Treatments for Safer and More Durable Tunnel Environments

AggreBind’s advanced solutions are specifically designed to enhance the safety and structural stability of tunneling projects:

• Dust Suppression in Tunnels: AggreBind locks in dust and contaminants, significantly improving air quality and protecting workers from respiratory risks during tunneling activities.
• Thermal and Structural Stability: AggreBind has been engineered to retain stability across extreme temperatures, from -57°C to 350°C and has proven long-term reliability in diverse environments. Its applications include ventilation shafts, tunnel linings, emergency access areas, entrance/exit portals and battery pad foundations for emergency systems and critical power infrastructure, ensuring safety and functionality of the installations.
• Water-Resistant Barrier: By forming a hydrophobic layer on tunnel surfaces, an AggreBind topical barrier effectively prevents moisture-related structural degradation and helps to mitigate the effects of hydrostatic pressure.
• Slope and Wall Stabilization for Tunnels: AggreBind is used to stabilise loose slopes and materials, and for reinforcing vertical tunnel walls, preventing erosion and dust generation caused by moisture and general operations.
• Improved Tunnel Walkways and Roadways: AggreBind enhances the durability and stability of the tunnel invert, ensuring safer walkways for workers and smoother roadways for machinery. Its application reduces dust, wear, and the need for frequent maintenance and watering in the high-traffic areas.
• Reduced Water Usage: Unlike conventional dust suppression that requires frequent application and heavy reliance on water trucks, AggreBind’s once-and-done approach eliminates the need for daily water-intensive treatments, reducing water waste, conserving resources, and supporting environmentally responsible tunnel construction.

AggreCrete: Enhancing Concrete Performance in Tunnel Projects

Concrete is integral to tunnel construction and AggreBind’s Polymer Modified Concrete (PMC) product, AggreCrete, is a cement additive which significantly enhances concrete performance in:

Flexibility and Strength in Tunnel Structures: The AggreCrete copolymer enhances the tensile strength and flexibility of concrete, minimizing cracking and improving its load-bearing capacity, critical to withstand the unique stresses, geological shifts, and dynamic loads common in tunnelling environments​.

Waterproof and Resilient Concrete for Harsh Tunnel Conditions: As a PMC, AggreCrete produces a fully hydrophobic concrete mass, preventing water ingress, leaching, and internal moisture build-up. Its resilience protects the concrete structure against deterioration caused by moisture and high-salinity environments, reduces risk of mold or algae growth, and maintains the structural integrity and longevity of tunnel walls and invert surfaces.

Corrosion Resistance and Structural Durability: By repelling water and sealing out moisture, AggreCrete PMC protects the concrete’s reinforcement steel from corrosion, maintaining the integrity of tunnel structures and ensuring greater durability and lifespan of the infrastructure, particularly in tunnels exposed to groundwater or corrosive substances.

Tunnel Maintenance and Operational Cost Savings: AggreCrete’s enhanced durability reduces the frequency of repairs such as crack filling or resealing, significantly lowering long-term maintenance costs, and the disruptions and downtime for tunnel operations.

Faster Curing and Environmental Benefits: AggreCrete accelerates curing times and reduces cement usage, enabling faster project completion while minimizing the environmental footprint of tunnel construction.
