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 vapour 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 Flexiprufe® adhesive onto the substrate at all horizontal areas.
- Unroll the Evalon® V waterproofing membrane onto the Flexiprufe® 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.
