ASBESTOS ENCAPSULATION

The Science of EPDM Encapsulation

Our system uses advanced EPDM technology that chemically bonds to the asbestos surface. This creates a permanent, airtight seal that effectively traps hazardous fibers, preventing them from becoming airborne while simultaneously providing a 100% waterproof barrier.

RPA Waterproofing utilises EPDM Rubber Membrane Systems to permanently encapsulate all asbestos roofings systems. Our system boasts a 20-Year product and workmanship guarantee that is FREE from maintenance making it the perfect encapsulating and waterproofing solution. Our consistently thick rubber membrane ensures uniform protection, zero manipulation to your current system and boasting quick and simple installation ensuring your no downtime to your operations.

Technical Specification (E-E-A-T Signal)

  • Material: 1.14mm Uniform EPDM Membrane.

  • Elongation: 465% (moves with your building to prevent cracks).

  • Resistance: Fully UV stable and hail resistant.

  • Eco-Friendly: Safe for rainwater harvesting (Inert material).

Key Benefits

  1. 20-Year Workmanship and Product Guarantee: Peace of mind for decades.

  2. FREE From Maintenance: No ongoing costs or labor required.

  3. No Protective Coatings Required (UV Stable): The membrane naturally resists UV damage without extra layers.

  4. Paintable: Can accept 2-4 coats of exterior acrylic paint (depending on colour) if aesthetic changes are desired.

  5. Inert Material: Doesn’t leach any chemicals into the environment making it perfect for rain water harvesting.

  6. Fire Retardant: Adds a layer of safety.

  7. 100 – Year Life Expectancy: A true long-term solution.

  8. Cold Installation: Our cold-bonded EPDM requires no heat, drilling, or mechanical fasteners. This ensures the asbestos substrate remains undisturbed, eliminating the risk of fiber release during installation.

  9. Cost Effective Alternative: (Depending on complexity and size) often cheaper than hazardous removal and replacement.

  10. Eliminate Hazardous Waste: Encapsulation avoids the high costs and environmental impact of disposing of asbestos at specialized landfills. It is the most eco-friendly way to manage and secure an aging roof.
