This document discusses roof gardening systems. It describes a green roof system as involving waterproofing, a drainage system, Typar geotextile for root protection and drainage, a lightweight growing medium, and plants. Green roofs can provide benefits like stormwater management, improved air and water quality, and increased energy efficiency. The document presents examples of existing and proposed roof garden projects, and international roof garden projects using green roof systems with drainage layers and Typar geotextile. It also analyzes issues with non-standardized roof gardens that can experience punctures, soil migration, and water seepage without proper waterproofing and drainage layers.

3. About Roof Gardening System
 A green roof system is an extension of the existing roof which
involves a high quality water proofing and root repellant
system, a drainage system, Typar geotextile, a lightweight
growing medium and plants.
 Green roof systems may be modular, with drainage layers,
Typar geotextile, growing media and plants already prepared
in movable, interlocking grids, or, each component of the
system may be installed separately. Green roof development
involves the creation of "contained" green space on top of a
human-made structure. This green space could be below, at or
above grade, but in all cases the plants are not planted in the
"ground'. Green roofs can provide a wide range of public and
private benefits.

4. Concept
• Upper Typar® layer prevents downwash of humus into the drainage
layer.
• Bottom Typar® SF layer protects the waterproof membrane from
puncturing and acts as a root barrier.

6. Features
• Light weight handling is easier.
• Flexibility around pillars and columns.
• Typar has high puncture resistance & high tear strength.
• Drastic reduction in the weight on the roof.
• Controls the accumulation of water and prevents heat from building up.
• Saving in the labor cost.
• Protecting the roof slab from plant / tree roots.
• Storm water management (through retention/filtration),.
• Water and air quality improvement.
• Noise reduction.
• Increased energy efficiency and biodiversity preservation.
