Densoband™ Setting a New Standard in Joint Sealing for Road and Pavement Construction

When it comes to building and maintaining roads, bridges, and runways, even the smallest details can make a significant difference in long-term durability. Joint sealing is one of those critical details-essential for protecting infrastructure from water ingress, erosion, and costly repairs. Densoband™ is a high-performance solution engineered to address these challenges and deliver lasting results.

Why Joint Sealing Matters

Roads and pavements are constantly exposed to heavy traffic, temperature fluctuations, and environmental stress. Without proper joint sealing, water and debris can penetrate vulnerable areas, leading to erosion, cracking, and structural damage. Densoband is designed to prevent these issues, offering a durable and effective barrier that safeguards your investment.

A real-world example of the importance of joint sealing can be seen in the Costco Wholesale case study. As the second largest retailer in the world, Costco faced concerns over heaving asphalt and potential customer injury and liability at their Orillia, Ontario location. To address these risks, Costco adopted Densoband to protect all asphalt-concrete joints around their buildings and gas stations throughout North America.

What Makes Densoband Different?

Densoband is a hot asphalt bituminous sealing strip developed for sealing joints between asphalt, concrete, and steel surfaces. Its unique polymer-modified bitumen composition provides outstanding flexibility and durability, allowing it to accommodate movement from heavy traffic and thermal changes. This ensures a uniform, watertight, and flexible seal that stands up to the harshest conditions.

In the Costco Orillia project, more than 500 linear meters of Densoband were installed around the apron of the building and the gas station. The product acted like a gasket, protecting joints from water infiltration and the damaging effects of freeze/thaw cycles, thereby prolonging the life of asphalt joints and preventing hazards to patrons.

Key Features

  • Excellent Flexibility: Accommodates expansion, contraction, and movement without cracking or propagating damage.
  • Uniform Watertight Seal: Prevents water ingress, reducing erosion and joint deterioration over time.
  • Excellent Adhesion: Bonds strongly to primed asphalt, concrete, or steel for long-lasting performance.
  • High Durability: Withstands heavy traffic loads and environmental stressors-ideal for high-traffic areas.
  • Easy, Safe Installation: Integrated adhesive system eliminates the need for flame application, improving safety and efficiency.
  • Versatile Application: Can be applied by hand or machine to suit a wide range of project requirements.
  • Minimal Maintenance: Reduces long-term maintenance costs and extends the lifespan of infrastructure.
  • Reliable in All Climates: Performs in temperatures from +41°F (+5°C) to +113°F (+45°C) and remains crack-free even at (32°F) 0°C.

Where Densoband Excels
