Denso North America benefits many infrastructure applications with the great anti-corrosion and sealing products that it makes, such as its petrolatum tape systems. The company has built on a long track record of helping Canadian municipal governments protect their remediation and redevelopment projects against corrosion and other forms of damage for many years. A few years ago, the City of Hamilton, Ont. put its trust in Denso petrolatum-tape solutions during a major redevelopment of Hamilton Harbour.
Remedy for uncontrolled water leaks
This project involves an environmental remediation and redevelopment of a section of the Hamilton Harbour, on the end of Lake Ontario. Two new piers were designed for construction, and the structures have been secured in place by thick sheet piling with two-inch tie rods and wale bolts. The City of Hamilton was concerned, understandably, about many potential threats to the piers’ integrity, like corrosion, weather-related expansion and contraction, and leaks through the tie-rod holes.
What was needed was a remedy for uncontrolled water leaks during construction of the piers. So the crew settled on Denso petrolatum tape systems, such as Denso Hi-Tack Primer, Hi-Tack Tape, and Densyl Mastic.
After they removed the failed caulking and foam, the workers filled the cavities with Densyl Mastic. This putty-like material was the perfect solution for the application, due to its density and sealing ability over a broad range of temperature fluctuations. It can also be contoured to fill irregular spaces and cover sharp edges. Workers then applied Hi-Tack Primer to the rods and the sheet piles’ vertical surfaces. Next, Denso Hi-Tack Tape was applied to cover the whole vertical surface around the interface, with a 50 per cent overlap going from horizontal coverage of the tie rods. Along with the Hi-Tack Primer, Hi-Tack Tape allows long-term adhesion in demanding environments.
Since the City completed the Hamilton Harbour redevelopment project, it has not had to worry about water egress and corrosion, and will not need to for more than 50 years. Denso will protect the new piers well before their expected lifespans. Trust Denso for the right solutions.
