Gain and maintain structural integrity for improved safety.Damage from hydrostatic pressure, corrosive chemicals in groundwater, years of extreme temperature fluctua-tions and inevitable tunnel accidents can compromise concrete and other tunnel construction materials. That puts the structural integrity of a tunnel at risk and can lead to unpredictable risks to public safety. The water-proofing materials must be designed and installed to mitigate these dangers. You can rely on CETCO to ensure your tunnel waterproofing is done right, the first time.

Comprehensive approach. Dependable products.CETCO provides integrated planning, design guidance and quality installation for tunnel waterproofing. Our 50-year track record speaks to the dependability of our products, commitment to quality and outstanding value. We serve the diverse needs of the tunneling industry in projects ranging from cut and cover applications to deep tunnel projects. Transportation and customized needs in a broad spectrum of environments and site-specific

Superior Technology. Composite Active Polymer Technology (APC)Removing and repairing failed waterproofing is not even possible in many circumstances without removing tons of overburden. That response is labor-intensive, noisy and expensive. Tunnels are often placed in highly sensitive locations where disruptions in their service can lead to major economic impacts to a region or city. That’s why a product with the ability to “heal itself” over time is crucial to tunnel waterproofing. COREFLEX® by CETCO has unique performance and installation characteristics to reduce the risk of water ingress in tunnels structures—saving time, cost and disruption.

Plan your tunnel waterproofing with assurance of superior performance.From deep tunnels bored through solid rock to cut-and-cover in frable gravel, tunnel waterproofing is one of the most de-manding and challenging sectors of the industry. Installing the right tunnel waterproofing material requires integrated plan-ning and a comprehensive understanding of the project structure and purpose. In addition to the wide range of products suited for these unique challenges, CETCO offers deep expertise in planning, consultation and installation to ensure a low-maintenance, watertight structures for generations.

High performance waterproofing products for tunnels

The Hydroshield Quality Assurance Program is a systematic approach to ensure optimum, long-term waterproofing performance necessary for tunneling projects. No other waterproofing manufacture can match the peace of mind that comes with expert consultation, strategically managed installation, contractual accountability and a no-dollar-limit warranty. Our reputation for long-term performance and superior customer service is based on more than 50 years of waterproofing success around the world.

IndependenT InSpeCTIonSEffective waterproofing inspections require a well- coordinated field effort. Compliance with project requirements during installation and subsequent work by other trades can be monitored by third-party independent inspection hired by the owner.
