Roof Garden - bring your roof to life

BRANZ Appraised
Viking’s Roof Garden is New Zealand’s only BRANZ appraised roof garden system using a sheet waterproofing membrane.

System Approach
The Viking Roof Garden is a complete system - not a concoction of parts cobbled together. It’s an internationally tested and proven, proprietary system made up of specialised components.

MIRAdrain G4 Component

This drainage board composite is a multi-purpose 3-in-1 critical component that provides: an absorbent moisture retention layer to keep soil damp; a series of cups and holes that both retain and release water in controlled volumes, and a protection layer to ensure the root barrier below isn’t damaged. 

Aluminium Drainage Boxes
Specific to the Viking Roof Garden system, these boxes promote the drainage of stormwater while simultaneously protecting the drains from clogging with soil.

• Electronic leak detection system
• Waterproofing membrane (Enviroclad or Anti-root Torch-On)
• Root barrier (for Enviroclad only)
• Drainage board composite (including protection fabric, drainage board cups and moisture retention layer)
• Plants and soil
• Aluminium drain protection box
• Aluminium garden edging

Key factors to consider:

• An appropriate waterproofing membrane layer
• The soil (a.k.a ‘growth medium’) having been specifically formulated for roof gardens eg: high draining soil full of pumice, compost and perlite
• Plants and grasses that aren’t too thirsty and don’t possess aggressive root structures
• A maintenance programme employed, or better still, proprietary watering system
