Combating Water Main Breaks with Carbon Fiber Solutions
As summer approaches, many cities in northern regions are dealing with the consequences of a brutal winter. Record low temperatures and heavy snowfall have left infrastructure under immense pressure, and now the thaw is causing new problems—like water main breaks. This period, often called "water main break season," is a recurring issue that affects communities worldwide. In Prince Albert, Saskatchewan, a persistent water main break has been flooding the streets for over a month, highlighting the urgent need for effective solutions.
The Causes Behind Water Main Breaks
One of the primary causes of water main breaks is the freeze-thaw cycle. As the ground thaws, it shifts, putting stress on underground pipes. Combined with aging infrastructure—some of which is nearly 100 years old—this creates a perfect storm for failures. In Prince Albert alone, there have been 19 water main breaks this season, with more expected. City officials are working to develop a long-term plan, acknowledging that the extreme cold last winter has significantly strained the underground system.
Corrosion: A Costly and Widespread Problem
Corrosion of pre-stressed concrete cylinder pipes (PCCP) is a major issue across North America. According to a 2002 study, corrosion costs U.S. water and wastewater systems over $50 billion annually. On average, 850 water main breaks occur each day, costing more than $3 billion in repairs. Leaking pipes also lead to massive water loss—around 2.5 trillion gallons per year, or about 17% of all water pumped in the U.S. Of that, 90% is due to corrosion in aging pipelines. A 2012 study from Utah State University found that 43% of U.S. water mains are between 20 and 50 years old, and 22% are over 50.
With almost half of the one million miles of pipelines beneath American streets nearing the end of their lifespan, replacement costs could exceed $1 trillion over the next 25 years. But with limited funding, we need innovative ways to extend the life of our critical infrastructure.
HJ3's CarbonSeal: A Game-Changing Repair Solution
HJ3’s CarbonSeal carbon fiber system offers a smart, durable, and cost-effective alternative to traditional repair methods. A real-world example is a cracked water pipe at a coal-fired power plant. The internal concrete lining of a 120-inch diameter pipe had developed cracks, allowing water to seep in and corrode the pre-stressed wires. Faced with the high cost of replacing the entire 750-foot section, the plant turned to HJ3’s CarbonSeal solution.
How the CarbonSeal Repair Works
The process began with cleaning the pipe using abrasive blasting, followed by sealing leaks with polyurethane foam. The surface was then primed, and saturated CarbonSeal fabric was carefully applied. A protective top coat was added to ensure a fully sealed, impermeable surface. Remarkably, the entire 750 feet of pipe was repaired in just 11 days, restoring its structural integrity. Compared to other repair methods, this approach saved 50%, and 65% compared to full replacement. It also prevented six tons of concrete from going to landfills.
After eight years of operation, the system continues to perform as expected. The client praised HJ3 for the support provided during design, engineering, and on-site execution.
