Waterproof layer thickness is generally 5-10 cm.
The roof pitches processing into natural drainage.
2. Mark the spaces of the flower beds, the location of the flower, roads, drainage channels, irrigation and drainage facilities on the roof in accordance with the design requirements
3.Building Construction
Construction building planting beds and garden ornaments according to the design,
4.Installation of Irrigation and Drainage Systems
