Viking Roof Garden System
Description

The focus on improving the quality of life in our urban environments and reducing the impact on our buildings, can be assisted with the installation of a Viking Roof Garden System. A roof garden is a roof that is partially or completely covered with vegetation and soil; lined by a membrane that ensures the living space below remains watertight.

As compelling as the idea of a roof garden can be, there are several facets that must be executed correctly to ensure a successful roof garden installation. A dead roof garden, or worse-still, a leaking one is a hugely expensive issue to resolve.

Key factors include:

  • An appropriate waterproofing membrane layer
  • Only trained applicators installing that membrane system – (to the manufacturer’s specification)
  • Proven roof garden drainage components that have been sourced from the same reputable manufacturer
  • 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
