Root penetration in construction materials can cause significant damage, from cracking roofing systems to weakening asphalt pathways.

Preventol B2, a biocide from Lanxess, offers a powerful solution to this problem by preventing root growth in bituminous materials such as roofing felts, sealants, insulation, and asphalt mixtures. This ensures long-lasting protection for your infrastructure, while not impacting or harming any surrounding plant life.

Roots can create a range of problems in construction materials, including:

• Structural Damage: Roots exert pressure on bituminous materials, causing cracks that weaken roads, pavements, and roofing systems.
• Water Infiltration: Cracks caused by roots allow water to penetrate, leading to further degradation and potential long-term damage.
• Increased Maintenance Costs: Ongoing repairs are required to address the damage caused by root penetration, raising overall maintenance expenses.
• Safety Hazards: Cracked surfaces present safety risks for pedestrians and vehicles, increasing the potential for accidents.

Preventol B2 prevents root growth upon contact with treated bituminous materials. When the roots come into direct contact with the material, they absorb a minimal amount of the active substance which in turn disrupts the root’s growth.  Eventually this causes the plant to stop growing in the direction of the treated bituminous material and the plant undergoes a process known as lignification, halting the root’s advancement at the contact zone. Due to the targeted action of Preventol B2 only the roots that come in direct contact with the treated material are affected, and this ensures that both the plant and the surrounding plant life remains unharmed, preserving the natural environment around your construction project.

Key Benefits of Preventol B2

• Long-Lasting Protection: Prevents root penetration for years, reducing the need for costly repairs and prolonging the lifespan of your infrastructure.
• Eco-Friendly: Safe for surrounding plants, making it an environmentally conscious choice.
• Versatile: Ideal for use in roofing systems, insulation, sealing compounds, asphalt, and rubber seals.
• Thermal Stability: Remains effective in varying climates and environmental conditions.
• High Compatibility: Easily integrates with bituminous materials and other construction substances.

Applications of Preventol B2

Preventol B2 is used in a variety of construction scenarios to safeguard infrastructure from root damage:

• Roofing Systems: Protects green roofs, garden roofs, and flat coverings from root penetration.
• Insulation: Prevents root intrusion in building insulation, pipelines, bridges, and hydraulic structures.
• Sealing Compounds: Ideal for drainage and sewer systems, where root intrusion can cause significant damage.
• Asphalt: Extends the life of farm tracks, cycle paths, park pathways, and other asphalt structures.
• Rubber Seals: Provides additional protection for rubber seals in various applications.

Proven Effectiveness: The Lupine Test Results

In the Lupine test, bituminous felt samples treated with Preventol B2 showed impressive results:

• 0.40% concentration: Minor root penetration observed, but no complete passage through the material.
• 0.50% & 0.60% concentrations: No root penetration.
• Blank Sample: Full root penetration.

These results demonstrate the remarkable efficiency of Preventol B2 in preventing root growth, even at low concentrations.

Preventol B2 is the ideal solution for preventing root penetration in construction materials and ensuring the longevity of your infrastructure. With its proven performance, eco-friendly formula, and cost-saving benefits, Preventol B2 offers unparalleled protection that helps you avoid expensive repairs and maintenance.

Safeguard your projects, reduce long-term costs, and ensure durable, root-free construction with Preventol B2.
