What is EVALON®

EVALON® waterproofing membranes are superior quality EVA membranes for single-ply waterproofing of all types of flat roof constructions and application methods as well as for waterproofing of foundations.

  • Metal/soft roof
  • Green roof
  • Inverted roof
  • Decks and terraces
  • Soft and flexible material
  • Surface does not retain dirt
  • Excellent thermal and mechanical properties over time
  • Resistant to solar radiation wear
  • Resistant to general chemical environmental impact
  • Allows water vapor to escape through the surface
  • British Board of Agrément (“BBA”) certificate with durability lifespan of at least 30
  • years
  • Manufactured to ISO 9001 quality assurance
  • FLL certified
  • Made in Germany
  • Green label
  • Elimination of dirt build-up on roof surface
  • Cost-effective as it does not require a geotextile separation layer
  • No risk of membrane being compromised because of plasticizer migration
  • Compatible with bitumen and polystyrene products
  • Excellent durability reduces future maintenance costs
  • Easily handled even with unconventional roof shapes
  • Helps to keep buildings cool
  • Can be installed under wear layers
  • Can be directly installed under a “green layer”
  • Resistant to root penetration
  • Can be recycled

Ensure that all surfaces are smooth, free from dust or loose materials and dry.

Clean and dry all surfaces before application of the adhesive. Apply a thick coat of Synthaprufe adhesive onto the substrate at all horizontal areas.

Unroll the EVALON® V waterproofing membrane onto the Synthaprufe while it is still tacky. Apply pressure from the centre to minimise air being trapped under the EVALON® V membrane. All laps shall be minimum 50 mm.

The EVALON® V fleece backed membrane shall be bonded and installed until the extent/ base of the parapet walls/ upturn areas. A separate unbacked EVALON® membrane shall be used on all vertical surfaces. The unbacked EVALON® membrane shall be terminated at 300 mm above from the structural level and bonded with an approved contact adhesive (Dunlop GP).

Care shall be taken so as not to damage the membrane after installation.
