Water Retention Box Wrb 85

Infiltration trough made of recycled PP intended for surface drainage in combination with a Flow Control System; high water retention potential, used for extensive green roofs with 0° roof pitch.

Optigrun Water Retentionbox WRB 170 on roofs used as retention areas, under extensive and intensive vegetation as well as traffic areas such as terraces, fire brigade access roads, car parks, etc.With closed, load-distributing structure For temporary and/or permanent storage of rainwater with regulated water discharge through a Flow Control System With Capillary Bridges to transport stored rainwater from the drainage level into the substrate layer and to increase evaporation High compressive strength With freely flowable structure for quick distribution of rainwater within the retention room Suitable for inverted roofs (when used on inverted insulation, no permanent water storage is possible)

Infiltration trough made of recycled PP intended for surface drainage in combination with a Flow Control System; high water retention potential, used for intensive green roofs with 0° roof pitch and varying layer heights.Base plate with load-distributing structure For temporary and/or permanent storage of rainwater with regulated water discharge through a Flow Control System High compressive strength With freely flowable structure for quick distribution of rainwater within the retention room Suitable for inverted roofs (when used on inverted insulation, no permanent water storage is possible

Optigrun Pitched Roof Board FKD 58SD is used for pitched roofs with a pitch in between 15° and 35°. Made from expanded polystyrene. With precisely fitting Z-fold on top and bottom edge and lateral indentations for safe shear stress transfer in direction of the water flow; no possibility of substrate reaching the protective layer thanks to tight fit of horizontal and lateral edges. The integrated chambers provide excellent anti-slippage for the substrate, high water storage capacity and an integrated water distribution system. Lay out according to manufacturer informations with max. 80 mm overfill (incl. vegetation mat).
