The Sika TBM App is a specialized set of tools designed for professionals working with Tunnel Boring Machines (TBMs). This suite combines three powerful applications that simplify complex calculations and optimize key processes in underground construction projects.

1. Backfill Grout Mix Design
Accurate mix design is critical for safe and efficient tunnel operations. This app enables engineers to calculate the optimal composition of backfill grout for annular gap filling behind the tunnel lining. It considers essential parameters such as cement, bentonite, water, and admixtures, ensuring precise ratios for performance and cost efficiency.

2. Tail Seal Grease Consumption
Tail seal grease plays a vital role in sealing the TBM shield and preventing water ingress. This app calculates grease consumption based on machine specifications and operating conditions. It helps maintenance teams plan usage, reduce waste, and maintain continuous protection during tunneling operations.

3. Soil Conditioning & Foam Agent Management
Effective soil conditioning is key to controlling excavation face pressure and improving TBM performance. This app assists in determining the correct dosage of foam agents and surfactants, evaluates soil conditioning parameters, and predicts consumption rates. It supports decision-making for various ground conditions, enhancing safety and productivity.
