Technical Statement
Product Description
Neuchâtel Permatec is a hybrid high-performance monolithic membrane, designed to provide exceptional longevity, ensuring it lasts for the entire lifetime of the building. Neuchâtel Permatec is a polymer modified bitumen applied over insulation board or a timber or concrete structural substrate in two layers with a nominal thickness of 6mm, and protection membrane to give a total thickness of up to 10mm.
Scope of use
Neuchâtel’s Permatec is a monolithic hot-melt designed for use as the waterproofing layer in new-build flat roofing (when covered by suitable protection), inverted roofs, green roofs and podium deck specifications. Permatec is melted on site in a purpose-built machine and applied in two coats to provide a tough, flexible, self-sealing membrane with built-in root inhibitor.
Ideal for demanding site conditions: Excellent low temperature flexibility and adhesion, Can be readily applied in low temperatures on a clean, dry, frost-free surface. Work can proceed during winter months, minimising lost construction time. Permatec is not affected by rain, snow or frost immediately after its application. Can be walked on immediately after installation of the system.

Maintenance requirements
All maintenance surveys should be carried out yearly and in the Autumn.
• It is important to check that roof outlets are functioning and gratings are not blocked. Remove
debris from the roof but do not flush silt or dead leaves down outlets. In areas where taller
trees are adjacent to the roof, inspections may be required more frequently.
• Note the general condition of the waterproofing finishes and report any damaged areas
immediately.
• Check waterproofing to roof light kerbs.
• Check roof light domes for signs of damage or deflection.
• Check perimeter details and up stands, ensuring that the metal capping, flashing's, edge trims
and mortar pointing to chase details are secure.
• Check flashings to expansion joints and that the all components are secure.
• Check the up stand flashings to plant support legs/up stands.
• Check the up stands and flashing's to pipe penetrations.
• Examine all mastic seals and repair/replace as necessary.
• Check walkways and around access
