Completed projects

Green roof, Doha office complex

Intensive green roof drainage across 9,000 m² under a tight dead-load budget.

Green roof, Doha office complex
The existing structure had only 180 kg/m² of spare capacity; a gravel drainage course would have exceeded it once saturated.

A 100 mm layer of 8–16 mm expanded clay brought the saturated weight of the drainage course to about 65 kg/m², freeing load budget for a deeper growing medium.

Scope of supply

  • Supply of 3,200 m³ in 1 m³ big bags
  • CIF sea freight to Hamad Port
