The Royal Condominium, Cambodia


To provide sub-surface drainage for the Intensive Green Roof on the rooftop of the condominium.


Elmich VersiCell® 3050 drainage modules (drain cells) were installed beneath the geotextile filter fabric layer and the planting soil above. The drainage cavity created enables rapid transport of excess water to drainage points on the roof, preventing waterlogging at the planter boxes and roof gardens. Laid directly on the waterproofing membrane, the modules also provide a protection layer that prolongs the serviceable life of the membrane.
