Extensive planting – more than a protective eco-layer

In line with the general trend towards eco-building, the extensive planting system has now been established for some time. However, it is much more than a simple protective eco-layer or a necessary balancing measure.

Extensive planting to suit individual requirements

The multi-layer construction, made up of a filter, drainage and vegetation layer, offers the best conditions for maintaining long-lasting, high quality extensive planting schemes.
