Method of fabricating an unsupported plant mat, especially for roof turfing.

摘要

The invention relates to a process for producing a support-free vegetation mat (10), in particular for cultivating roofs with greenery. In the prior art, pre-cultivated, support-free pieces of vegetation in the form of sods or rolled turf are known, in the case of which they are held together by the intensive root network of the grasses. Impairments occur, however, during transportation and storage as a result of the pressure loading to which the vegetation is subjected and the exclusion of air in the rolled-up state. A further critical disadvantage lies in the fact that types of plants which do not take root in such an intensive manner, e.g. succulent types of plants (Sedum), cannot, without supports, be produced and laid in a state in which they are held together. In such cases, the prior art takes as precondition, for cultivation and transportation, a support insert for the vegetation mats, this resulting, inter alia, in considerable environmental problems, sometimes high costs, and defective points with no vegetation. The invention remedies this in that it provides a stackable, dimensionally stable backing (12) which has bent-up borders (14) and in which the vegetation mat can be transported in the cultivated state and, upon laying, can be separated from the same by pushing or drawing off.
