Pourable Sealant PB 556: Hot Applied Elastic Filling Solution for Asphalt and Concrete Joints

Filling joints and cracks is crucial in areas subject to heavy loads and temperature fluctuations, such as road pavements, industrial areas, and airport runways. The sealant used in such applications must do more than simply seal cracks: it must tolerate movement, prevent water penetration, and be long-lasting. Pourable Sealant PB 556 is a hot-applied, high-performance elastic sealant developed to address these needs.

Hot-pour mastics are known as one of the most effective solutions for joint and crack repair, especially on asphalt and concrete surfaces. PB 556, with its formula optimized for asphalt pavements, provides high elasticity, excellent adhesion, and durability. The hot-pour application method creates a strong bond to the surface, minimizing the risk of deformation for many years.

Why Should We Use Pouring Sealant PB 556?

Pourable Sealant PB 556 effectively fills joints and cracks in asphalt and concrete surfaces, preventing water and other harmful substances from seeping into the infrastructure. This prevents damage to infrastructure materials from freeze-thaw cycles and extends the life of the surface.

One of its greatest advantages is its elastic structure. It remains flexible and resistant to expansion and contraction caused by temperature changes. It performs particularly well in continental climates and in areas with high day-night temperature differences on asphalt surfaces.

PB 556 is also resistant to dynamic loads caused by traffic, making it suitable for use on roads with heavy traffic and in industrial areas. This makes it not only a repair solution but also a long-term investment.

Ease of Application and Workmanship Advantages

Hot-applied sealants are typically applied by specialized teams using professional equipment. PB 556's homogeneous formula flows smoothly when heated, completely filling the joint or crack. During application, air bubbles and voids are minimized, and it adheres perfectly to the surface.

Additionally, its rapid cooling and hardening properties allow for rapid opening to traffic. This feature saves time and money, especially in high-traffic areas. Joint and crack repairs performed with PB 556 do not require long-term maintenance, providing a significant advantage in planning maintenance budgets.

Where is it used?

PB 556 has many different applications. Here are the main examples:

• Asphalt Pavements: Joint and crack repairs on highways, urban roads, parking areas and service roads.

• Concrete Surfaces: Concrete roads, bridge superstructures, airport runways and aprons.

• Industrial Areas: Crack and joint filling operations on heavy load-bearing surfaces such as factory areas, port and pier areas.

• Infrastructure Projects: Crack repairs near sewer or drainage systems to protect infrastructure by preventing water passage.

Long-Lasting and Durable Solution

The most significant advantage of PB 556 is its formula, designed to withstand harsh climate conditions and heavy traffic loads. It chemically bonds to the surface during hot application, providing excellent waterproofing. It also prevents cracking and separation caused by freeze-thaw cycles.

Its long-lasting performance also extends maintenance intervals, reducing operating costs. It maintains its flexibility and integrity even in areas with intense temperature fluctuations.

With PB 556, your roads, bridges, runways and all surfaces will serve safely for many years.
