THE PROBLEM

Sheet pile walls prior to Butyl 35 application
Sheet Pile Close Up

Ellis Dam required the installation of 215 meters of sheet piles to support a major infrastructure upgrade. A key challenge was ensuring corrosion protection for the sheet pile walls, which are exposed to harsh environmental conditions. At the outset, there were no established case studies to demonstrate the effectiveness of the Denso Butyl 35 system for sheet pile applications, leading to some skepticism regarding its performance.






CUSTOMER

Surespan Group, the supplier and installer, was tasked with ensuring the sheet piles received durable, long-lasting protection against corrosion and water intrusion. Collaborating with the leading general contractor in British Columbia, Surespan required a solution that could be applied efficiently while meeting the strict project deadlines.

THE SOLUTION: DENSO BUTYK 35 TAPE & PRIMER

Cross Country Canada supplied Denso Butyl 35 Tape and primer as the chosen corrosion prevention system.

  • Denso Butyl 35 Tape: A polyethylene-backed, cold-applied tape with a butyl rubber adhesive, providing excellent adhesion, water resistance, and UV stability.

  • Denso Butyl Primer: A fast-drying primer designed to maximize adhesion and ensure uniform application of the tape.

  • The product was applied to the sheet pile walls, offering a protective layer to prevent corrosion while ensuring water resistance. The system’s adaptability to flat sheet pile surfaces showcased its versatility beyond traditional pipe applications.



RESULTS

  • Seamless and efficient application: The project team, led by Wil Barnett, was extremely satisfied with how quickly and easily the Denso system was installed.

  • Durability: The system demonstrated exceptional performance, ensuring long-term protection for the sheet piles against corrosion and environmental factors.

  • Versatility: This project proved the effectiveness of Denso Butyl 35 Tape for non-pipe applications, opening doors for its use in various industries and infrastructure projects.

 BENEFITS:

  1. Enhanced Corrosion Protection: Prevents damage from harsh environments, extending the lifespan of the sheet piles.

  2. Efficiency: Cold-applied, with no need for specialized equipment, reducing installation time and labor costs.

  3. Proven Performance: Successfully applied to sheet piles, setting a new benchmark for versatility in corrosion prevention.

  4. Customer Confidence: The successful outcome alleviated initial skepticism and established Denso Butyl 35 as a reliable choice for infrastructure applications.



The Ellis Dam Upgrade project highlighted the adaptability and performance of Denso Butyl 35 Tape and primer, positioning Cross Country Canada as a key partner in delivering innovative, field-proven solutions for infrastructure challenges. This project not only met its goals but also demonstrated the potential for expanding the application of Denso products to new market sectors.
