  1. Roof Garden Waterproofing System

  2. Roof Garden – Today’s Advantages • Reduces urban heat island effects • Storm water runoff management • Adds valuable/useable space providing economic benefits • Energy efficiency year-round • Could earn LEED points

  3. Roof Gardens Kaiser Resources Vancouver, BC After Before Create high value, usable space

  4. Roof Gardens • Rockefeller Center – 1933 Enhances view from neighboring buildings

  5. Roof Garden - Design Principles For Effective Waterproofing Systems: • Select highly puncture resistant membrane • Establishredundancy – Splice overlayment • Provide positive drainage at membrane level

  6. Roof Garden - Design Principles • Ensure proper system protection • Incorporate drainage layer/root barrier • UtilizeMoisture Retention Mat (where applicable)

  7. Roof Garden Assembly Types • Ultra-Extensive/Shallow– < 4” deep • Extensive/Medium– 4” - 8” deep • Intensive/Deep – > 8” deep

  8. Shallow Assembly •  Growth Media • Moisture Retention Mat • Drainage Board • Protection Fabric • Membrane ( Adhered )  Dens-Deck • Approved Insulation  Substrate

  9. Ultra-Extensive/Shallow Assembly Growth Media – “Sedum”

  10. Ultra-Extensive/Shallow Assembly

  11. Medium Assembly •  Growth Media • Moisture Retention Mat • Drainage Board • Root Barrier  Protection Fabric  Membrane ( Adhered )  Dens-Deck  Approved Insulation  Substrate

  12. Roof Garden – Medium Assembly

  13. Deep Assembly •  Growth Media  Protection Fabric  Drainage Gravel • Protection Fabric • Root Barrier • Extruded Polystyrene  Membrane ( Adhered )  Dens-Deck  Approved Insulation

  14. Intensive Assembly/Deep

  15. Protection/Drainage Components In addition to the waterproofing material, other components must be utilized to ensure proper function: • Protection Fabric • Drainage Boards • Moisture Retention Mat • Extruded Polystyrene Insulation • Root Barrier

  16. Planting Media • Planting media should meet the following criteria: • Not include silt that can clog drainage fabric • Provide permanent aeration • Provide adequate drainage • Supply or absorb water and nutrients • Retain its original volume

  17. Planting Media • Planting Media Mix: • A mix suitable for most roof garden applications should be similar in content and percentage or composed of • 45% graded sand ( with no fines ) • 45% expanded shale • 10% humus ( pine bark )

  18. Weights of Plant Media lbs/ft3
