SAFETY & PERFORMANCE CONDAT Emergency solutions to protect tunnel boring machines

At AFTES exhibition, CONDAT will showcase its solutions designed to manage critical situations involving tunnel boring machines. The goal: to help teams preserve the machine’s integrity, ensure the safety of operations, and minimize the operational and economic consequences of on-site incidents.

In underground construction, water infiltration and waterproofing failures can quickly jeopardize the continuity of tunneling operations, operator safety, and project timelines. CONDAT addresses these challenges with a range of emergency solutions designed to adapt to the various configurations encountered on-site.

Controlling water infiltration in both static and dynamic conditions

For interventions under static conditions, CONDAT BLOCK solution creates an effective waterproof barrier. It stops water infiltration and ensures the safety of intervention and maintenance operations before excavation restarts.

Under dynamic conditions, the WRS provides a complementary solution for emergency waterproofing needs. It allows excavation to continue under critical conditions while reducing downtime that could result in significant costs for the project.

These solutions are part of a practical approach to managing unforeseen events and optimizing your performance by safeguarding the tunnel boring machine and controlling costs associated with downtime. They provide teams with the means to respond quickly, limit the impact of incidents, and facilitate a controlled resumption of operations.

Protecting the main bearing, a strategic component of the tunnel boring machine

CONDAT will also highlight its expertise in ensuring watertightness at the tunnel boring machine’s head and protecting the main bearing. As an essential component of the machine, the main bearing must be protected from any intrusion of water or soil that could damage it. In the event of a problem, the consequences are critical: a prolonged stop in tunneling and significant repair or replacement costs.

With the Emergency Labyrinth Seal (ELS) and the GR 130 2500 EP3 and TG MAX 2800 greases, CONDAT offers an effective solution for a reinforced barrier against water and soil ingress. This is an optimal combination for protecting the main bearing even under critical or degraded conditions.

With this product offer, CONDAT reaffirms its commitment to supporting tunneling professionals throughout their operations, including during the most critical phases. Recognized for its on-site knowledge, formulation expertise, and understanding of the unique challenges of mechanized tunneling, the CONDAT team is more dedicated than ever to providing operational, reliable, and safety-focused solutions.
