- Vegetated grid pavers consist of concrete bricks with gaps/funnels between the single bricks

- Use of concrete bricks or plastic grid - Gaps/grid is filled with soil, grass seeds, rocks

- After storm water event: water trickles/infiltrates through gaps/funnels between bricks into the underlying gravel and then into the soil or groundwater

- Infiltrated water is also taken up by plants

- Water is stored for a certain period in the soil and drainage layer

- Additional drainage conveys water into sewage system

- Used in parking areas and roadways

- Function:

o reduced surface runoff

o water filtering

o water storage delayed runoff

Role of Nature / Mode of Action: 
- Imitating natural soils  natural soils are permeable - Natural drainage effect of soils - different permeability of soils depending on the soil type and the saturation with water - different infiltration potential - soil with large pores absorbs larger amount of water than sealed surface - filling material between bricks enables water infiltration on high level
Technical & Design Parameters: 
- Concrete bricks or plastic grids are filled with soil, seeds or stones - Grass grows in concrete/plastic grid - Maintenance necessary
Benefits & Limitations: 
Benefits: - storm water management - reduced surface runoff - controlled infiltration - temporary water storage - water filtering Limitations /disservices - visual appearance
