Green Roof Drainage

Many flat roofs are already used as green roofs. The challenge in drainage is keeping soil and gravel away from the drain and ensuring water inflow.

LORO offers special attachments for flat roof drains and parapet drains.

Inspection Chamber for Flat Roof Drains in Green Roofs

The specially developed inspection chamber for LORO-X DRAINLET flat roof drains secures water inflow from the soil layer through its elongated openings on the sides. Access to the flat roof drain for maintenance and cleaning is ensured via the removable cover.

Parapet Drainage in Green Roofs with Screen Unit

The screen unit with special hole pattern for LORO-X RAINSTAR parapet drains with gravity flow is the space-saving option for drains directly at the parapet. The screen unit is mounted on the drain flange instead of the LORO-X hood. Note: The screen unit cannot be used for siphonic flow!
