RamTough KLB-100

SEBS Hot Rubberized Asphalt

RamTough KLB-100 is part of the RamTough KLB-100 Hot Applied SEBS Modified Asphalt Elastomeric BUR System

RamTough KLB-100 SEBS rubber material’s web-like molecular structure creates a microscopic, elastic network of strong, rubberized strands with tough, interlocking styrene end blocks. During the polymerization process, the polymer network absorbs the asphalt light ends, producing a rubberized waterproofing material with properties that are far superior to regular oxidized roofing grade asphalt.

RamTough KLB-100 when combined with appropriate modified bitumen membranes, polyester or fiberglass ply sheets or cap sheets, delivers a compatible composite roofing membrane with extraordinary toughness, puncture and impact resistance. RamTough KLB-100 is also recommended for buildings intolerant of water intrusion for high performance requirements. When the building design requirements are for a long-life cycle, RamTough KLB-100 is a cost-effective solution.

  • Built-up roofing
  • Plaza deck waterproofing systems
  • Protected membrane roofs (IRMA®)
  • Green Roof Roofscapes®
  • Vertical waterproofing applications
  • Parking decks, bridges, water treatment plants
  • Between slab waterproofing membrane systems
  • Superior Elastomeric Waterproofing
    SEBS-modified asphalt creates a flexible, fully adhered, monolithic membrane with performance far exceeding standard oxidized asphalt.
  • Exceptional Crack Bridging & Flexibility
    Its elastic polymer network allows the membrane to move with structural expansion and contraction without compromising waterproofing integrity.
  • High Puncture & Impact Resistance
    When reinforced with polyester, fiberglass plies, or cap sheets, RamTough KLB-100 delivers a composite membrane with outstanding toughness and durability.
  • Outstanding Adhesion & Compatibility
    Designed to integrate seamlessly with modified bitumen membranes and BUR systems for a fully bonded, watertight assembly.
  • Ideal for Critical Waterproofing Applications
    Recommended for buildings where even minor water intrusion cannot be tolerated—such as commercial roofs, plaza decks, foundations, and high-risk structures.
  • Long-Life System Performance
    Engineered for longevity, making it a cost-effective solution for projects requiring extended service life and reduced maintenance.
  • Enhanced Chemical Resistance
    The SEBS formulation resists deterioration from environmental exposure, oils, and industrial pollutants.
  • Part of a Complete System
    As a core component of the RamTough KLB-100 Hot Applied SEBS Modified Asphalt Elastomeric BUR System, it delivers proven performance backed by Barrett’s industry expertise.

Project Profiles

Belle Square is a dynamic complex integrating four main components: residential, office, retail and parking in the center.

Project Profiles

In 1992, a major renovation program was conceived by none other than Der Scutt, the architect responsible for a number of downtown New York’s most notable superstructures. Included in this renovation was the need for a new roof.
