Retention under Accessible Roofs
Our Systems RE 80 - The Sustainable Solution and RE 150 - The Strong Solution
Our systems RE 80 and RE 150 are suitable for a sustainable retention of excess water under accessible roofs
Top layer: Concrete paving stones, thickness 8 to 10 cm
Bedding: Chippings 0/5, application height 3 to 5 cm
Base layer: Crushed stones 0/32 or 0/45, application height 10 to 15 cm
Filter layer: Quality fleece PP 350 g/m², GRK 5
Water storage: Retention-element RE 80* or RE 150 (*not shown)
Protection, separation and sliding layer: TGL 550, GRK 5
Sliding layer: Construction foil PE-LD 0.2 mm
The system RE 80 - The Sustainable Solution and RE 150 - The Strong Solution are in combination with a dam-up element suitable for a sustainable retention of excess water on vehicle accessible roofs. The big storage volumes of RE 80 and RE 150 care for an efficient relief of the public sewerage system.
No matter if RE 80 - The Sustainable Solution or RE 150 - The Strong Solution are applicated under a green roof or under accessible surfaces, both are strong systems - they bear high load-capacities, store big quantities of water and relieve effectively the public sewerage system.

Retention under Intensive Green Roofs
Our Systems RE 80 - The Sustainable Solution and RE 150 - The Strong Solution
Our systems RE 80 and RE 150 are also suitable for a sustainable retention of excess water under green roofs
Planting: Trees, bushes, perennials, grass
Growing medium: Intensive substrate Hydrotop-I, application height at least 20 cm
Filter layer: Quality fleece PP 150 g/m², GRK 3
Water storage: Retention element RE 80* or RE 150 (*not shown)
Protection layer: Geotextile Standard PES/PP 800 g/m²
The systems RE 80 - The Sustainable Solution and RE 150 - The Strong Solution are in combination with a dam-up element also suitable for a sustainable retention of excess water on green roofs. In case of heavy rainfall the big storage volumes of RE 80 and RE 150 care for an efficient relief of the sewerage system. The retained water can be stored for a long supply of trees, bushes, perennials and grass on intensive green roofs.
The high compression strength of RE 80 - The Sustainable Solution - and RE 150 - The Strong Solution makes them also applicable on walkable or car accessible roofs.
