Optigrün international AG

Optigrün Drainage Gutters and Terrace Grids are used for draining surface water from roof outlets, draining water-bearing layers, draining driving rain from the façade, as collection channels for draining green roof areas and as branch canals between downpipes and roof outlets.

The principle behind the patented Meander system is as simple as it is effective – water flows along a winding route from one chamber to another, just like a naturally meandering river or stream. During heavy rainfall the chambers of the board are filled with water and it passes from one chamber to the next causing a long delay in the discharge of excess water. The Meander 60 board, for instance, extends the water flow length by a factor of 13. Each Meander 30 board covers two square metres yet the water flow route inside it measures up to 46 metres in length.

Observance of fixed restrictions on discharge

With the Optigrün System Solution Retention Roof Flow Control, which is suitable for green roofs (extensive, intensive) and even for public areas (accessible to vehicles and pedestrians), specified restrictions on discharge can be verifiably observed. The centrepiece of the newly developed system solution is the Optigrün Water Retention Box WRB with Flow Control System. The flow control solution regulates the maximum drainage rate and creates an additional storage area on the roof of max. 80 l/m²

Anchor points secured by superimposed load and used with personal protective equipment (PPE) for maintenance and care.
Optigrün international AG offers a variety of solutions through Optisafe which are all based on the same principle: fall protection system secured by superimposed load of the green roof; does not damage the roof membrane. There are four Optisafe variants which are used in different scenarios.
