Green roof water retention.

System solutions with defined water retention. Such an extensive green roof will have a water retention capacity up to 44 l m and a surface weight in water saturated condition about 130 kg m.

Drainage and water retention elements with low medium or high retention capacity are components of the green roof system. However a purple roof retains more water than any other green roof concept.
